很簡單，以下：javascript

父頁面:（彈出提示框）css

function newwindow(obj)html

{java

var rtn = window.showModalDialog('NewPage.htm','','status=no,scrollbars=no,top=20,left=110,width=420,height=165');node

var div = document.getElementById("div1");mysql

div.innerHTML=rtn;jquery

}web

子頁面：ajax

function pageinit()正則表達式

{

var lab = document.getElementById("infoimage");

window.returnValue=lab.value;

window.close();

}

---------------------------父窗體

function Show()

{

var bb=2;

var a=window.showModalDialog("彈出2.aspx","","dialogwidth=500px;dialogheight=500px;");

document.getElementById("Text1").value=a;

}

-----------------------------子窗體

function Button1_onclick() {

var a=document.getElementById("TextBox1");

window.returnValue=a.value;

window.close();

------------------window.dialogArguments

}

-------------------------------------------------後臺調用前臺js函數；

ClientScript.RegisterStartupScript(ClientScript.GetType(), null, "<script>guo('fffff');</script>");

--------------------------sd可使name,或者是Id；

document.all("sd").style["height"]=h;//設置樣式,js控制樣式

-------------------------調節透明度

#guo {

filter:alpha(opacity=50);

}

</style>

--------------------------------調用客戶端事件：

ScriptManager.RegisterStartupScript(UltraWebGrid1, typeof(UltraWebGrid), "null", "<script>window.parent.gb('T');</script>", false);

---------------調用frame框架外的函數：

------------------iframe獲取父頁面的元素

window.parent.document.getElementById("Text1").value="hahhahhaha";

父親獲取兒子

JS版：document.getElementById("IframeID").contentWindow.document.getElementById("divID")

--------------------------------js星期：

var day=["日","一","二","三","四","五","六",];

document.write("星期"+day[new Date().getDay()]);

-----------------------------------

Infragistics.WebUI.UltraWebListbar.UltraWebListbar bar = new Infragistics.WebUI.UltraWebListbar.UltraWebListbar();

bar.ID = "menu";

bar.SkinID = "MenuBar";

bar.ApplyStyleSheetSkin(Page);

//bar.Width=

//bar.Height = "100%";

bar.Groups.Clear();

YongHuModel userModel= Session["LoginUser"] as YongHuModel;

int roleId = userModel.RoleId.Id;

IList<RoleLines> roleLines = RoleLinesManager.GetSYSMenu(roleId);

foreach (RoleLines roleItem in roleLines)

{

if (roleItem.LinkId.ParentId == 0)

{

//Infragistics.WebUI.UltraWebNavigator.Node root = new Node();

//root.Text = roleItem.LinkId.Name;

//root.DataKey = roleItem.LinkId.Id;

//root.Expanded = true;

//root.ImageUrl = "~/XtGlMk/images/base.gif";

TreeNode root = new TreeNode();

root.Text = roleItem.LinkId.Name;

root.Value = roleItem.LinkId.Id.ToString();

root.Expanded = true;

root.NavigateUrl = "";

Infragistics.WebUI.UltraWebListbar.Group group = new Infragistics.WebUI.UltraWebListbar.Group(root.Text);

MyTemplate tem = new MyTemplate();

tem.Lines = roleLines;

tem.Root = root;

group.Template = tem;

bar.Groups.Add(group);

}

bar.DataBind();

Panel1.Controls.Add(bar);

---------------------------------------listbar:

Infragistics.WebUI.UltraWebListbar.Group group = new Infragistics.WebUI.UltraWebListbar.Group("aa");

Infragistics.WebUI.UltraWebListbar.Item ite1 = new Infragistics.WebUI.UltraWebListbar.Item();

ite1.Text = "aaaa";

group.Items.Add(ite1);

this.UltraWebListbar1.Groups.Add(group);

----------------------------------------

ScriptManager.RegisterStartupScript(UpdatePanel1, typeof(UpdatePanel), "Button2",

"<script>alert('請選擇要刪除的行！');</script>", false);

------------------------------------------scriptmanage中使用控件netadvantage可以使用；webconfig文件

</httpHandlers>

---------------------------

<p style="padding-top:5px;">歡迎您</p> 若換成<span>就很差用了；

------------------------viewstate相似於static

-------------------------分頁：

string sql2 = "select top " + page.PageSize + " * from GongSi where BH not in(select top " + page.Start + " BH from GongSi)";

---------------------------gridview中添加控件

<igtbl:TemplatedColumn Width="200px">

操做

</HeaderTemplate>

<asp:LinkButton ID="LinkButton1" runat="server" OnClick="LinkButton1_Click" Width="80px">下屬用戶</asp:LinkButton>

</CellTemplate>

</Header>

</Footer>

</igtbl:TemplatedColumn>

---------------------------------------------------------------------------------獲取gridview的表格值，cell值：

Session["Id"] = UltraWebGrid1.DisplayLayout.SelectedCells[0].Row.Cells[0];

Session["Id"] = UltraWebGrid1.DisplayLayout.SelectedRows[0].Cells[0].ToString();

案例：

if (UltraWebGrid2.DisplayLayout.SelectedCells[0] != null)

{

if (UltraWebGrid2.DisplayLayout.SelectedCells[0].Row != null)

{

int id = Convert.ToInt32(UltraWebGrid2.DisplayLayout.SelectedCells[0].Row.Cells[0].Text);

Session["XgGsID"] = id;

Response.Redirect("XgGongSi.aspx");

}

else

{

ScriptManager.RegisterStartupScript(UpdatePanel1, typeof(UpdatePanel), "Button2",

"<script>alert('請選擇要修改的行！');</script>", false);

}

else

{

if (UltraWebGrid2.DisplayLayout.SelectedRows[0] != null)

{

int id = Convert.ToInt32(UltraWebGrid2.DisplayLayout.SelectedRows[0].Cells[0].Text);

Session["XgGsID"] = id;

Response.Redirect("XgGongSi.aspx");

}

else

{

ScriptManager.RegisterStartupScript(UpdatePanel1, typeof(UpdatePanel), "Button2",

"<script>alert('請選擇要修改的行！');</script>", false);

}

-------------------------------------------------------------------------------------------

----------------listbox添加項：

foreach (YongHuModel model in yhgl_models)

{

ListItem li = new ListItem();

li.Text = model.MC.ToString();

li.Value = model.BH.ToString();

cblJZXM.Items.Add(li);

}

------------------------------------------------listbox:添加移除列；

cblJZXM.Items.Add(li);

//移除

cblXM.Items.RemoveAt(i);

------------------------------------------------彈出框案例：

父頁面案例：彈出提示框

function Button1_onclick() {

window.showModalDialog("子.aspx",this,"dialogHeight:450px;dialogWidth:800px;status=no");

}

function show(str)

{

document.getElementById("Text1").value=str;

}

</script>

//子頁面案例：後臺---

ScriptManager.RegisterStartupScript(UpdatePanel1, typeof(UpdatePanel), "null",

"<script>window.dialogArguments.addgs('" + GYSBH + "','" + MC + "');window.close();</script>", false);

必須在head內添加：

-----------------------------------後臺獲取前臺session值：

string dataBaseName=System.Web.HttpContext.Current.Session["XmName"].ToString();

//--------------------------------------查詢某數據庫某個表：

SELECT * FROM CC ..AA

------------------------------------------

cmd.Parameters.AddRange(values);//循環添加sqlparameters

-----------------------------------------------------------------

using(SqlDataReader sdr=DBHelper.GetReader(sql1))，使用using的前提是對象類必須是實現：Idispose接口；

{

if (sdr.Read())

{

return 0;

}

--------------------------------------------------------------------------------------------------前臺：

function IfGoDel(bh)

{

if(confirm("是否同時刪除合格供應商名冊與供應商複覈裏的數據？"))

{

document.getElementById("hidCommond").value="allDel";

document.getElementById("hidXtBH").value=bh;

}else

{

document.getElementById("hidCommond").value="Only";

document.getElementById("hidXtBH").value=bh;

}

// __doPostBack("UpdatePanel1","");

document.form1.submit();

}

--------後臺:

string commond = Request.Form["hidCommon"];

if (commond == "Search")

{

Bind(1);

}

string commd = Request.Form["hidCommond"];

string xtbh = Request.Form["hidXtBH"];

if (commd == "allDel")

{

int key = Convert.ToInt32(xtbh);

bool bb = GysFpManager.dropGysFPByBH(key);

if (bb)

{

ScriptManager.RegisterStartupScript(UpdatePanel1, typeof(UpdatePanel), "Button2",

"<script>alert('刪除成功！');</script>", false);

Bind(1);

}

else

{

ScriptManager.RegisterStartupScript(UpdatePanel1, typeof(UpdatePanel), "Button2",

"<script>alert('刪除失敗！');</script>", false);

}

if (commd == "Only")

{

return;

}

-----------------------------------數據庫分頁；

List<GysModel> GysS = new List<GysModel>();

List<SqlParameter> pars = new List<SqlParameter>();

string searchSql = CreatSql(searchModel, pars);

string selectCount = "select count(*) from Gys where (FHJG=1 or FHJG is null ) " + searchSql;

page.TotalRow = Convert.ToInt32(DBHelper.GetScalar(selectCount, pars.ToArray()));

StringBuilder sql = new StringBuilder("select * from (select row_number() OVER (ORDER BY BH desc) AS rowId,* from Gys where (FHJG=1 or FHJG is null )");

sql.Append(searchSql).Append(")as Temp where rowId between ").Append(page.Begin).Append(" and ").Append(page.End);

using (SqlDataReader dr = DBHelper.GetReader(sql.ToString(), pars.ToArray()))

{

while (dr.Read())

----------------------------------------添加事務：

begin transaction

insert into A(c1,c2) values(v1,v2);

insert into B(c3,c4) values(v3,v4);

insert into C(c5,c6) values(v5,v6);

if @@ERROR = 0

begin

commit transaction;

end

else

begin

rollback transaction;

end

---------------------------這條語句是正確的

cn = new SqlConnection("data source=DELL-PC\\AA;uid=sa;pwd=sa");

cn.Open();

StringBuilder sb = new StringBuilder(" use CC update [User] set UName='666' where UId="+i+"");

-----------------------------這條語句也是正確的；

cn = new SqlConnection("data source=DELL-PC\\AA;initial catalog=CC; uid=sa;pwd=sa");

cn.Open();

StringBuilder sb = new StringBuilder(" use CD update [User] set UName='666' where UId="+i+"");

---------------------------------同時對兩個數據庫進行操做

try

{

int i = 1;

cn = new SqlConnection("data source=DELL-PC\\AA;initial catalog=CC; uid=sa;pwd=sa");

cn.Open();

StringBuilder sb = new StringBuilder("begin transaction ");

sb.Append("use CC update [User] set UName='xiao' where UId=1");

sb.Append("use CD update [User] set UName='xiao' where UId=1");

sb.Append("if @@ERROR = 0 begin commit transaction end else begin rollback transaction end");

SqlCommand cmd = new SqlCommand(sb.ToString(), cn);

cmd.ExecuteNonQuery();

}

------------------------------

cmd.Parameters.AddRange(values);

--------------------------------------

List<GysFhModel> GysFhS = new List<GysFhModel>();

List<SqlParameter> pars = new List<SqlParameter>();

string searchSql = CreatSql(searchModel, pars);

string selectCount = "select count(*) from GYSFH left join GYS on GYSFH.GYSBH=GYS.BH where 1=1 " + searchSql;

page.TotalRow = Convert.ToInt32(DBHelper.GetScalar(selectCount, pars.ToArray()));

StringBuilder sql = new StringBuilder("select * from (select row_number() OVER (ORDER BY GYSFH.BH desc) AS rowId,GYSFH.* ,GYS.MC from GYSFH left join GYS on GYSFH.GYSBH=GYS.BH where 1=1 ");

sql.Append(searchSql).Append(")as Temp where rowId between ").Append(page.Begin).Append(" and ").Append(page.End);

------------------------javascript:後臺提交

document.getElementById("HiddenField1").value="1233434";

var b=document.getElementById("HiddenField2");

window.form1.submit();

接收 if (IsPostBack)

{

TextBox1.Text = HiddenField1.Value.ToString();

}

------------------------將數據庫備份到指定位置；

backup database cc to disk='D:\d3.bak'

-----------------------將備份還原到某個位置並附加數據庫：格式不能變化；

restore database SJCL33 from disk='D:\Company\通用版\JC.Web\File\BakSource\TSSJCL.bak' with FILE = 1, move 'SJCL' to 'C:\Users\dell\Desktop\s\SJCL33.mdf',move 'SJCL_Log' to 'C:\Users\dell\Desktop\s\SJCL33.LDF',NOUNLOAD, REPLACE, STATS = 10

---------------------------

document.write("瀏覽器名稱: " + navigator.appName + "<br>");

document.write("版本號: " + navigator.appVersion + "<br>");

document.write("代碼名字: " + navigator.appCodeName + "<br>");

document.write("用戶代理標識: " + navigator.userAgent);

---------------------------bit類型數據存儲

插入時能夠存：

INSERT INTO Users(Sex) VALUES('TRUE');

0爲false,1爲true;

或者直接插入0或1；插入時除了整形不帶單引號其他都帶；

顯示時也爲True或false;

-----------------------------存儲過程整形做爲條件

ALTER PROCEDURE dbo.selectuser

(

@UId int,

@result nvarchar(20) output

)

declare @s nvarchar(100)

set @s=@UId

declare @str nvarchar(1000)

set @str='select @result=UName from [User] where UId='''+@s+''''//一個或是三個單引號都行；如果整形，先賦值給字符型就好了

EXEC sp_executesql @str, N'@result nvarchar(20) OUTPUT', @result OUTPUT

--------------------------------數據庫分頁存儲過程

"select UName from [User] where UName like '%"+ss+"%'"

ALTER PROCEDURE dbo.SelectPages

(

@name int,

@pageSize INT, --每頁顯示的索引號

@pageIndex INT, --每頁顯示的記錄數

@count INT OUTPUT --總記錄數

)

begin

declare @na nvarchar(20)

set @na=@name

declare @sqlstrc nvarchar(2000)

declare @sqlstrd nvarchar(2000)

set @sqlstrc='select @count=count(*) from Fen where Name>'''+@na+''''

exec sp_executesql @sqlstrc, N'@count int output',@count output

set @sqlstrd='select Name from (select Name,ROW_NUMBER() OVER (ORDER BY Id) AS SerialNumber from Fen where Name>'''+@na+''') as t'

set @sqlstrd=@sqlstrd+' WHERE t.SerialNumber > ' + CONVERT(NVARCHAR(100), (@pageIndex - 1) * @pageSize) +

' AND t.SerialNumber <= ' + CONVERT(NVARCHAR(100), @pageIndex * @PageSize)

exec (@sqlstrd)

end

,sum(Score) as 總成績

from Score

GROUP BY name,Sex WITH CUBE

--當出現with rollup 根據by後面第一個字段分組進行彙總，聚合性別；

--若group by sex,Name WITH rollup則根據性別分組，聚合姓名；(男的有多少，女的有多少)

---若with cube,則以group by 後面的多列進行分組，多個維度分組；by後的第一個字段；(順序爲:根據性別聚合,總聚合,根據名稱聚合)

------------count(1)和count（*）是等效的，都會返回本列的行數；

-------------------------------------------------------------------統計報表（合計、小計：cube rollup grouping的用法）

create table #t(a int,b int,c int,d int,e int)

insert into #t values(1,2,3,4,5)

insert into #t values(1,2,3,4,6)

insert into #t values(1,2,3,4,7)

insert into #t values(1,2,3,4,8)

insert into #t values(1,3,3,4,5)

insert into #t values(1,3,3,4,6)

狀況一：只有一個分類彙總列時，只須要一個合計。只須要增長with rollup便可。（一個維度的）

select case when grouping(a)=1 then '合計' else cast(a as varchar) end a,

sum(b),sum(c),sum(d),sum(e) from #t group by a with rollup

狀況二:有多個分類彙總列，只須要一個合計.增長rollup以後，須要增長判斷。

select case when grouping(a)=1 then '合計' else cast(a as varchar) end a,

sum(c),sum(d),sum(e) from #t

group by a,b with rollup

having grouping(b)=0 or grouping(a)=1

select case when grouping(a)=1 then '合計' else cast(a as varchar) end a,

sum(d),sum(e) from #t

group by a,b,c with rollup

having grouping(c)=0 or grouping(a)=1

狀況三：有多個分類彙總列，須要所有的小計和合計

select case when grouping(a)=1 then '合計' else cast(a as varchar) end a,

case when grouping(b)=1 and grouping(a)=0 then '小計' else cast(b as varchar) end b,

case when grouping(c)=1 and grouping(b)=0 then '小計' else cast(c as varchar) end c,

sum(d),sum(e) from #t

group by a,b,c with rollup

另一種顯示小計的方式

select case when grouping(a)=1 then '合計'

when grouping(b)=1 then cast(a as varchar)+'小計'

else cast(a as varchar) end a,

case when grouping(b)=0 and grouping(c)=1

then cast(b as varchar)+'小計' else cast(b as varchar) end b,

case when grouping(c)=1 and grouping(b)=0

then '' else cast(c as varchar) end c,

sum(d),sum(e) from #t

group by a,b,c with rollup

狀況四：有多個分類彙總列，須要部分的小計和合計

select case when grouping(a)=1 then '合計' else cast(a as varchar) end a,

case when grouping(c)=1 and grouping(b)=0 then '小計' else cast(c as varchar) end c,

sum(d),sum(e) from #t

group by a,b,c with rollup

having grouping(a)=1 or grouping(b)=0

---

select case when grouping(a)=1 then '合計' else cast(a as varchar) end a,

case when grouping(b)=1 and grouping(a)=0 then '小計' else cast(b as varchar) end b,

sum(d),sum(e) from #t

group by a,b,c with rollup

having grouping(a)=1 or grouping(b)=1 or grouping(c)=0

select case when grouping(a)=1 then '合計' else cast(a as varchar) end a,

case when grouping(c)=1 and grouping(b)=0 then '小計' else cast(c as varchar) end c,

sum(d),sum(e) from #t

group by a,b,c with rollup

----------------------------------數據庫時間函數的調用

1. 當前系統日期、時間

select getdate()

2. dateadd 在向指定日期加上一段時間的基礎上，返回新的 datetime 值

例如：向日期加上2天

select dateadd(day,2,'2004-10-15') --返回：2004-10-17 00:00:00.000

3. datediff 返回跨兩個指定日期的日期和時間邊界數。

select datediff(day,'2004-09-01','2004-09-18') --返回：17

4. datepart 返回表明指定日期的指定日期部分的整數。

SELECT DATEPART(month, '2004-10-15') --返回 10

5. datename 返回表明指定日期的指定日期部分的字符串

SELECT datename(weekday, '2004-10-15') --返回：星期五

6. day(), month(),year() --能夠與datepart對照一下

select 當前日期=convert(varchar(10),getdate(),120)

,當前時間=convert(varchar(8),getdate(),114)

select datename(dw,'2004-10-15')

select 本年第多少周=datename(week,'2004-10-15')

,今天是周幾=datename(weekday,'2004-10-15')

函數參數/功能

GetDate( ) 返回系統目前的日期與時間

DateDiff (interval,date1,date2) 以interval 指定的方式，返回date2 與date1兩個日期之間的差值 date2-date1

DateAdd (interval,number,date) 以interval指定的方式，加上number以後的日期

DatePart (interval,date) 返回日期date中，interval指定部分所對應的整數值

DateName (interval,date) 返回日期date中，interval指定部分所對應的字符串名稱

參數 interval的設定值以下：

值縮寫（Sql Server） Access 和 ASP 說明

Year Yy yyyy 年 1753 ~ 9999

Quarter Qq q 季 1 ~ 4

Month Mm m 月1 ~ 12

Day of year Dy y 一年的日數,一年中的第幾日 1-366

Day Dd d 日，1-31

Weekday Dw w 一週的日數，一週中的第幾日 1-7

Week Wk ww 周，一年中的第幾周 0 ~ 51

Hour Hh h 時0 ~ 23

Minute Mi n 分鐘0 ~ 59

Second Ss s 秒 0 ~ 59

Millisecond Ms - 毫秒 0 ~ 999

access 和 asp 中用date()和now()取得系統日期時間；其中DateDiff,DateAdd,DatePart也同是能用於Access和asp中，這些函數的用法也相似

舉例：

1.GetDate() 用於sql server :select GetDate()

2.DateDiff('s','2005-07-20','2005-7-25 22:56:32')返回值爲 514592 秒

DateDiff('d','2005-07-20','2005-7-25 22:56:32')返回值爲 5 天

3.DatePart('w','2005-7-25 22:56:32')返回值爲 2 即星期一(週日爲1，週六爲7)

DatePart('d','2005-7-25 22:56:32')返回值爲 25即25號

DatePart('y','2005-7-25 22:56:32')返回值爲 206即這一年中第206天

DatePart('yyyy','2005-7-25 22:56:32')返回值爲 2005即2005年

SQL Server DATEPART() 函數返回 SQLServer datetime 字段的一部分。

SQL Server DATEPART() 函數的語法是：

DATEPART(portion, datetime)

其中 datetime 是 SQLServer datetime 字段和部分的名稱是下列之一： Ms for Milliseconds

Yy for Year

Qq for Quarter of the Year

Mm for Month

Dy for the Day of the Year

Dd for Day of the Month

Wk for Week

Dw for the Day of the Week

Hh for Hour

Mi for Minute

Ss for Second

詳細的說明:

一般，你須要得到當前日期和計算一些其餘的日期，例如，你的程序可能須要判斷一個月的第一天或者最後一天。大家大部分人大概都知道怎樣把日期進行分割（年、月、日等），而後僅僅用分割出來的年、月、日等放在幾個函數中計算出本身所須要的日期！在這篇文章裏，我將告訴你如何使用DATEADD和DATEDIFF函數來計算出在你的程序中可能你要用到的一些不一樣日期。

在使用本文中的例子以前，你必須注意如下的問題。大部分可能不是全部例子在不一樣的機器上執行的結果可能不同，這徹底由哪一天是一個星期的第一天這個設置決定。第一天（DATEFIRST）設定決定了你的系統使用哪一天做爲一週的第一天。全部如下的例子都是以星期天做爲一週的第一天來創建，也就是第一天設置爲7。假如你的第一天設置不同，你可能須要調整這些例子，使它和不一樣的第一天設置相符合。你能夠經過@@DATEFIRST函數來檢查第一天設置。

爲了理解這些例子，咱們先複習一下DATEDIFF和DATEADD函數。DATEDIFF函數計算兩個日期之間的小時、天、周、月、年等時間間隔總數。DATEADD函數計算一個日期經過給時間間隔加減來得到一個新的日期。要了解更多的DATEDIFF和DATEADD函數以及時間間隔能夠閱讀微軟聯機幫助。

使用DATEDIFF和DATEADD函數來計算日期，和原本從當前日期轉換到你須要的日期的考慮方法有點不一樣。你必須從時間間隔這個方面來考慮。好比，從當前日期到你要獲得的日期之間有多少時間間隔，或者，從今天到某一天（好比1900-1-1）之間有多少時間間隔，等等。理解怎樣着眼於時間間隔有助於你輕鬆的理解個人不一樣的日期計算例子。

一個月的第一天

第一個例子，我將告訴你如何從當前日期去這個月的最後一天。請注意：這個例子以及這篇文章中的其餘例子都將只使用DATEDIFF和DATEADD函數來計算咱們想要的日期。每個例子都將經過計算但前的時間間隔，而後進行加減來獲得想要計算的日期。

這是計算一個月第一天的SQL 腳本：

SELECT DATEADD(mm, DATEDIFF(mm,0,getdate()), 0)

咱們把這個語句分開來看看它是如何工做的。最核心的函數是getdate()，大部分人都知道這個是返回當前的日期和時間的函數。下一個執行的函數DATEDIFF(mm,0,getdate())是計算當前日期和「1900-01-01 00:00:00.000」這個日期之間的月數。記住：時期和時間變量和毫秒同樣是從「1900-01-01 00:00:00.000」開始計算的。這就是爲何你能夠在DATEDIFF函數中指定第一個時間表達式爲「0」。下一個函數是DATEADD，增長當前日期到「1900-01-01」的月數。經過增長預約義的日期「1900-01-01」和當前日期的月數，咱們能夠得到這個月的第一天。另外，計算出來的日期的時間部分將會是「00:00:00.000」。

這個計算的技巧是先計算當前日期到「1900-01-01」的時間間隔數，而後把它加到「1900-01-01」上來得到特殊的日期，這個技巧能夠用來計算不少不一樣的日期。下一個例子也是用這個技巧從當前日期來產生不一樣的日期。

本週的星期一

這裏我是用周(wk)的時間間隔來計算哪一天是本週的星期一。

SELECT DATEADD(wk, DATEDIFF(wk,0,getdate()), 0)

一年的第一天

如今用年(yy)的時間間隔來顯示這一年的第一天。

SELECT DATEADD(yy, DATEDIFF(yy,0,getdate()), 0)

季度的第一天

假如你要計算這個季度的第一天，這個例子告訴你該如何作。

SELECT DATEADD(qq, DATEDIFF(qq,0,getdate()), 0)

當天的半夜

曾經須要經過getdate()函數爲了返回時間值截掉時間部分，就會考慮到當前日期是否是在半夜。假如這樣，這個例子使用DATEDIFF和DATEADD函數來得到半夜的時間點。

SELECT DATEADD(dd, DATEDIFF(dd,0,getdate()), 0)

深刻DATEDIFF和DATEADD函數計算

你能夠明白，經過使用簡單的DATEDIFF和DATEADD函數計算，你能夠發現不少不一樣的可能有意義的日期。

目前爲止的全部例子只是僅僅計算當前的時間和「1900-01-01」之間的時間間隔數量，而後把它加到「1900-01-01」的時間間隔上來計算出日期。假定你修改時間間隔的數量，或者使用不一樣的時間間隔來調用DATEADD函數，或者減去時間間隔而不是增長，那麼經過這些小的調整你能夠發現和多不一樣的日期。

這裏有四個例子使用另一個DATEADD函數來計算最後一天來分別替換DATEADD函數先後兩個時間間隔。

上個月的最後一天

這是一個計算上個月最後一天的例子。它經過從一個月的最後一天這個例子上減去3毫秒來得到。有一點要記住，在Sql Server中時間是精確到3毫秒。這就是爲何我須要減去3毫秒來得到我要的日期和時間。

SELECT dateadd(ms,-3,DATEADD(mm, DATEDIFF(mm,0,getdate()), 0))

計算出來的日期的時間部分包含了一個Sql Server能夠記錄的一天的最後時刻(「23:59:59:997」)的時間。

去年的最後一天

鏈接上面的例子，爲了要獲得去年的最後一天，你須要在今年的第一天上減去3毫秒。

SELECT dateadd(ms,-3,DATEADD(yy, DATEDIFF(yy,0,getdate()), 0))

本月的最後一天

如今，爲了得到本月的最後一天，我須要稍微修改一下得到上個月的最後一天的語句。修改須要給用DATEDIFF比較當前日期和「1900-01-01」返回的時間間隔上加1。經過加1個月，我計算出下個月的第一天，而後減去3毫秒，這樣就計算出了這個月的最後一天。這是計算本月最後一天的SQL腳本。

SELECT dateadd(ms,-3,DATEADD(mm, DATEDIFF(m,0,getdate())+1, 0))

本年的最後一天

你如今應該掌握這個的作法，這是計算本年最後一天腳本

SELECT dateadd(ms,-3,DATEADD(yy, DATEDIFF(yy,0,getdate())+1, 0))

本月的第一個星期一

好了，如今是最後一個例子。這裏我要計算這個月的第一個星期一。這是計算的腳本。

select DATEADD(wk, DATEDIFF(wk,0,

dateadd(dd,6-datepart(day,getdate()),getdate())), 0)

}同時使用纔有效果；

------------------------------frame去掉邊框：

---------------------------------------------------------:

decimal(18,6);

-----------------------------虛擬表：#表名；

---timestamp:時間戳，二進制數據；

----WAITFOR delay '00:00:005'：數據庫時間延遲

---SELECT @@rowcount;返回上一操做所影響的行數，若是大於0，可判斷操做是否成功；

處理併發：悲觀：（事務+鎖）；樂觀（時間戳）

悲觀處理方式是採用SQLSERVER數據庫中「事務+鎖」！（隔離級別總共四種默認level1）會產生髒讀；

　　先上僞代碼再解釋：

　　1.先解釋2個要用到的鎖

　　SELECT * FROM table WITH (HOLDLOCK) 其餘事務能夠讀取表，但不能更新刪除（避免不可重複讀），避免統一事務屢次讀取結果一致防止他人修改；

　　SELECT * FROM table WITH (TABLOCKX) 其餘事務不能讀取表,更新和刪除

　 SELECT * FROM table WITH (updLOCK) 其餘事務能讀取表,但不能更新

　　PS：這2個是表級鎖，要鎖行加上SQL過濾條件便可。數據庫的默認隔離級別是readcommit,(更改的事務未完成，其它不能讀取)

也就是level1;，可讀：能夠查詢+with(holdlock),若想不可讀，with(tablockx)

2.樂觀：事務+時間戳；

------------------如何避免死鎖 1 使用事務時，儘可能縮短事務的邏輯處理過程，及早提交或回滾事務；

2 設置死鎖超時參數爲合理範圍，如：3分鐘-10分種；超過期間，自動放棄本次操做，避免進程懸掛；

3 優化程序，檢查並避免死鎖現象出現； 4 .對全部的腳本和SP都要仔細測試，在正是版本以前。

5 全部的SP都要有錯誤處理（經過@error） 6 通常不要修改SQL SERVER事務的默認級別。

不推薦強行加鎖

------------------------------------時間戳：（微軟建議用rowversion）

convert(bigint,time)，對應c#int64進行比較便可；

--------------------別面內存泄露的方法，在一個類中建立另外一個類的實例時，當不用了，賦值null,這樣就告訴系統，能夠回收了；

------恢復數據庫:

restore database guo from disk='路徑備份' with recovery

------------------經典的dispose();垃圾回收gc（回收時將對象賦值爲null）,告訴回收器，我已經不被引用了，隨時清理；

class A:IDisposable

{

private bool isDisposed = false;

public void Dispose()

{

Dispose(true);

GC.SuppressFinalize(this);//告訴回收器清理已完成，無需調用析構函數；

}

protected virtual void Dispose(bool disposing)

{

if (!isDisposed)

{

if (disposing)

{

//釋放託管資源

}

//釋放非託管資源

}

isDisposed = true;

}

~A()//有回收期調用，不固定；

{

Dispose(false);

//主要清理非託管；

}

-------------------------------------文件流，數據庫的鏈接，系統的窗口句柄，打印機資源等等網絡鏈接，這些是非託管資源；

-----產生內存泄露的緣由：

文件流，數據庫的鏈接，系統的窗口句柄，打印機資源等等

------------

1.內存泄露的緣由：

！使用靜態引用；

！爲退訂的事件；

！爲調用的Dispose方法；

！使用不完全的Dispose方法；

等等；

內存泄露：Fabrice稱，內存泄漏發生在一塊內存不再被使用，但卻依然被程序所引用時

使用靜態引用

未退訂的事件－做者認爲這是最多見的內存泄漏緣由

未退訂的靜態事件

未調用Dispose方法

使用不完全的Dispose方法

在Windows Forms中對BindingSource的誤用

未在WorkItem/CAB上調用Remove

------------

對象的建立者或擁有者負責銷燬對象，而不是使用者

當再也不須要一個事件訂閱者時退訂此事件，爲確保安全能夠在Dispose方法中退訂

當對象再也不觸發事件時，應該將對象設爲null來移除全部的事件訂閱者

當模型和視圖引用同一個對象時，推薦給視圖傳遞一個此對象的克隆，以防止沒法追蹤誰在使用哪一個對象

對系統資源的訪問應該包裝在using塊中，這將在代碼執行後強制執行Dispose

---------------------------

用上面的SQL語句還原備份數據庫時，數據庫的狀態老是「正在還原」，使得不能對它進行其餘操做。

解決方案：「RESTORE DATABASE " + dbName + " From disk='" + filePath + "' WITH REPLACE,RECOVERY ";

-----------通常還原數據庫的話是 with replace;

----------------備份知識

一、SQL數據庫恢復模型

----------------------------------------------------------------------

1）徹底恢復模型

-----------------

（1）備份時要備份數據庫的數據文件和日誌文件

（2）還原時使用數據庫的備份的數據文件副本和所有日誌信息來恢復數據庫。

（3）能還原所有數據，並能夠將數據庫恢復到任意指定的時刻。

（4）爲保證明現即時點恢復，對數據庫的全部*做都將完整地記入日誌，這樣，日誌佔用空間較大，對性能也有所影響。

------------------

（2）大容量日誌記錄恢復模型

------------------

（1）備份時要備份數據庫的數據文件和日誌文件

（2）還原時使用數據庫的備份的數據文件副本和所有日誌信息來恢復數據庫。

（3）日誌中不記錄*做細節（如select into、create index等），而只記錄*做的最終結果，所以佔用日誌空間小。

（4）只支持將數據庫還原到事務日誌備份的時刻，而不支持即時點恢復，所以可能產生數據丟失。

-------------------

（3）簡單恢復模型

-------------------

（1）備份時只備份數據文件，還原時也用備份的數據文件恢復數據庫。

（2）只能將數據恢復到數據文件備份的時刻，可能產生最多的數據丟失。

（3）不適於生產系統和大規模*做環境下選用。

-----------------------------------------

alter database d1 set recovery simple --設置數據庫恢復模型

alter database d1 set recovery bulk_logged

alter database d1 set recovery full

----------------------------------------------------------------------

二、備份設備

----------------------------------------------------------------------

1）物理設備

---------------------------

disk：支持本地磁盤或者網絡備份

tape：支持磁帶機備份

name pipe：支持第三方備份軟件

---------------------------

2）邏輯設備

---------------------------

永久備份文件：能夠重複使用，應該在備份前建立。

臨時備份文件：用於一次性備份，在備份時建立。

-------------------------------------------------

exec sp_addumpdevice 'disk','bak2','e:\back_device\bak2.bak' --建立永久磁盤備份設備

exec sp_addumpdevice 'disk','bak3','e:\back_device\bak3.bak'

----------------------------------------------------------------------

exec sp_addumpdevice 'disk','bak4','\\sv2\backup\bak4.bak' --建立網絡永久磁盤備份設備

exec sp_addumpdevice 'disk','bak5','\\sv2\backup\bak5.bak'

----------------------------------------------------------------------

exec sp_dropdevice 'bak5' --刪除備份設備

----------------------------------------------------------------------

backup database d3 to bak3 --將數據庫備份到備份設備

backup database d4 to bak4

----------------------------------------------------------------------

restore headeronly from bak2 --查看備份設備中的內容

----------------------------------------------------------------------

backup database d3 to disk='e:\back_file\d3.bak' --將數據庫備份到臨時備份文件

backup database d4 to disk='e:\back_file\d4.bak'

----------------------------------------------------------------------

restore database d3 from bak3 --從備份設備還原數據庫

restore database d4 from disk='e:\back_file\d4.bak' --從備份文件還原數據庫

----------------------------------------------------------------------

三、使用多個備份文件存儲備份

----------------------------------------------------------------------

1）SQL可同時向多個備份文件進行寫*做。若是把這些文件放到多個磁帶機或磁盤中，則可提升備份速度。

2）這多個備份文件必須用同業型的媒體，並放到一個媒體集中。

3）媒體集中的文件必須同時使用，而不能單獨使用。

4）能夠經過format命令將媒體集從新劃分，但原備份集中的數據不能再使用。

--------------------------------------------------------------------

backup database d4 to bak4,bak5,bak6 with medianame='bak456',format --備份D4並造成Media Set

backup database d3 to bak4 --失敗，因Media set中文件必須同時使用

backup database d3 to bak4,bak5,bak6 --成功，將D3也備份到Media Set中

restore headeronly from bak4,bak5,bak6--查看Media Set中的備分內容

----------------------------------------------------------------------

backup database d4 to bak4 with medianame='bak4',format --從新劃分Media Set

backup database d3 to bak5,bak6 with medianame='bak56',format

----------------------------------------------------------------------

backup database d1 to bak1 with init --with init重寫備份設備中內容

backup database d2 to bak1 with noinit --with noinit將內容追加到備份設備中

restore headeronly from bak1

----------------------------------------------------------------------

四、備份的方法

----------------------------------------------------------------------

1）徹底備份

-------------------------------------------

（1）是備份的基準。在作備份時第一次備份都建議使用徹底備份。

（2）徹底備份會備份數據庫的全部數據文件、數據對象和數據。

（3）會備份事務日誌中任何未提交的事務。由於已提交的事務已經寫入數據文件中。

--------------------------------------------

backup database d1 to bak1 with init --徹底備份

backup database d1 to bak1 with noinit

----------------------------------------------------------------------

2）差別備份

---------------------------------------------

（1）基於徹底備份。

（2）備份自最近一次徹底備份以來的全部數據庫改變。

（3）恢復時，只應用最近一次徹底備份和最新的差別備份。

-----------------------------------------------

backup database d2 to bak2 with init,name='d2_full' --差別備份，第一次備份時應作徹底備份

create table b1(c1 int not null,c2 char(10) not null)

backup database d2 to bak2 with differential,name='d2_diff1'

insert b1 values(1,'a')

backup database d2 to bak2 with differential,name='d2_diff2'

insert b1 values(2,'b')

backup database d2 to bak2 with differential,name='d2_diff3'

insert b1 values(3,'c')

backup database d2 to bak2 with differential,name='d2_diff4'

restore headeronly from bak2

----------------------------------------------------------------------

3）事務日誌備份

-------------------------------------------------------------

（1）基於徹底備份。

（2）爲遞增備份，即備份從上一次備份以來到備份時所寫的事務日誌。

（3）容許恢復到故障時刻或者一個強制時間點。

（4）恢復時，須要應用徹底備份和徹底備份後的每第二天志備份。

-------------------------------------------------------------

backup database d3 to bak3 with init,name='d3_full' --日誌備份，第一次備份時應作徹底備份

create table b1(c1 int not null,c2 char(10) not null)

backup log d3 to bak3 with

insert b1 values(1,'a')

backup log d3 to bak3 with

insert b1 values(2,'b')

backup log d3 to bak3 with

insert b1 values(3,'c')

backup log d3 to bak3 with

restore headeronly from bak3

----------------------------------------------------------------------

create table b1(c1 int not null,c2 char(10) not null) --Full+Log+Diff

backup log d4 to bak4 with

insert b1 values(1,'a')

backup log d4 to bak4 with

insert b1 values(2,'b')

backup database d4 to bak4 with differential,name='d4_diff1'

insert b1 values(3,'c')

backup log d4 to bak4 with

insert b1 values(4,'d')

backup log d4 to bak4 with

insert b1 values(5,'d')

backup database d4 to bak4 with differential,name='d4_diff2'

restore headeronly from bak4

----------------------------------------------------------------------

日誌清除

-----------------------------------------

1）若是日誌空間被填滿，數據庫將不能記錄修改。

2）數據庫在作徹底備份時日誌被截斷。

3）若是將'Trans log on checkpoint'選項設爲TRUE，則結果爲不保存日誌，即沒有日誌記錄，不建議使用。

4）with truncate_only和with no_log設置日誌滿時清除日誌

5）with no_truncate則能夠完整保存日誌，不清除，即便在數據文件已經損壞狀況下。主要用於數據庫出問題後在恢復前使用。能夠將數據還原到出故障的那一時刻。

-------------------------------------------

exec sp_dboption d3

exec sp_dboption

sp_dboption 'd3','trunc. log on chkpt.','true' --設置自動清除數據庫日誌

sp_dboption 'd3','trunc. log on chkpt.','false' --將自動清除數據庫日誌的選項去除

----------------------------------------------------------------------

backup log d4 with truncate_only --設置D4日誌滿時清除日誌，並作清除記錄

----------------------------------------------------------------------

backup log d4 with no_log --設置D4日誌滿時清除日誌，但不作清除記錄

----------------------------------------------------------------------

backup log d4 to bak4 with no_truncate--在D4數據庫損壞時立刻備份當前數據庫日誌(DEMO)

--------

使用no_truncate

徹底+修改1+差別+修改2+差別+修改3+中止SQL，刪除數據庫數據文件+重啓SQL

backup log no_truncate

再還原，可還原到修改3

-----------------------------數據庫恢復順序；

恢復數據庫中的數據，因此一般恢復的時間較長；先恢復最後一次全庫備份，再恢復最後一次差別備份，

再順序恢復最後一次差別備份之後進行的全部事務日誌備份

------------------數據庫四種備份；

1）徹底數據庫備份

徹底數據庫備份是備份數據庫的全部表的數據及模式，以及對應的文件結構，包括對事務日誌中的事務進行備份。它能夠用做系統出現故障時恢復數據庫的基礎，也可用於在另一臺計算機上生成數據庫的副本。

（2）差別數據庫備份

差別數據庫備份只記錄自上次徹底數據庫備份後發生變化的數據。差別備份的數據量比徹底備份的數據量小並且備份速度快，所以能夠更常常地備份。

（3）事務日誌備份

事務日誌包含了自上次進行徹底數據庫備份、差別數據庫備份或事務日誌備份以來所完成的事務。可使用事務日誌備份將數據庫恢復到特定的即時點或恢復到故障點。

（4）數據庫文件和文件組備份

只備份特定的文件或文件組，經常使用於超大型數據庫的備份。

---------------------------------------------------------數據併發，其多個用戶修改其它用戶正在使用的資源，併產生了必定的影響；

level0:(read uncommitted)；修改未提交時，即可以讀取；---致使髒讀；解決方案：SET tran isolation level read uncommitted

個事務讀到另一個事務尚未提交的數據，咱們稱之爲髒讀

level1(read committed):(sql默認，(修改的過程當中不容許讀和修改)修改時(修改的進程還沒結束)，另外一進程不能讀取)read committed;---致使不可重複讀：解決方案:讀取的事務中設置SET tran isolation level repeatable read;

一個事務前後讀取同一條記錄，但兩次讀取的數據不一樣，咱們稱之爲不可重複讀。讀取的過程當中（5秒鐘內），有其它事務修改了數據；

level2:（repeatable read）,{原理：進行了s鎖，做用（小於with(holdlock),由於，le2不容許修改，因此不會出現不可重複讀，但出現幻讀，能夠插入，而holdlock不容許，這就是區別）

}解決方案：set tran isolation level serializable;:串行化（我的認爲是holdlock原理）：

一個事務前後讀取一個範圍的記錄，但兩次讀取的紀錄數不一樣，咱們稱之爲幻象讀；（幻讀，讀的時候有數據插入，不可重複讀，讀的時候有數據修改）

level3:(serializable)串行化:避免了幻讀；

-------更改隔離類別；

BEGIN transaction

SET tran isolation level read uncommitted

update -----

IF @@error=0

COMMIT transaction

else

ROLLBACK transaction

-------------------------------默認的level1:在修改中不容許修改和查詢，單容許插入；（插入不會引發不一致和完整性）

----------with(holdlock):查詢時，不容許修改和插入操做，容許查詢；

----------with(tablockx):查詢時什麼都不容許；

-------------------這兩個鎖只能應用在查詢上；

總結

事務隔離級別是經過數據庫的鎖機制來控制的，在不一樣的應用場景須要應用不一樣的事務隔離級別，

SQL Server默認的事務隔離級別是READ COMMITTED，默認的隔離級別，已經能夠知足咱們大部分應用的需求。

--------------------------行級鎖：鎖的粒度小；不想表級鎖，updlock,告訴你們，標記我整個事務將要更改，大家不要進行操做；

//$("ul").css("background-color","red");

//$("ul").attr("style", "background-color:red; font-size:20px;");

//$("ul").attr({ style: "background-color:red;",style: "background-color:red;"});

$("ul").attr("class", "lii");

$("ul").removeAttr("class");

-------------------------

$("p").addClass("selected highlight");

------------------得到索引：

.index();從0開始，返回一個數字；

-----------有的話，刪除，沒有的話添加；

$("ul").click(function () {

$(this).toggleClass("lii");

});

--------------not:除此以外的；

$("li").not($("li:last")).css("background-color", "red");

-------------2,3只選擇第三個，2,4只選擇第三和第四個，索引從0開始；當slice(2),表示從第三個到最後一個；

$("li").slice(2，3).css("background-color", "red");

---------------------lt:前四個；

$("li:gt(4)").css("background-color", "red");

-------全部的li;

$("ul").children().css("background-color", "red");

--------class爲dd的類；

$("ul").children(".dd").css("background-color", "red");

-------------全部的同級元素；

$("#f").nextAll().css("background-color", "red");

-----------挨着的第一個同級元素；

$("#f").next().css("background-color", "red");

-----------同級直到table標記之間的同級標記，不包括table;

$("#f").nextUntil("table").css("background-color", "red");

-------------找到全部父級的標記；

$("#nei").parents().css("background-color","red");

-------------應該只有上一級；

$("#nei").parent().css("background-color","red");

-------------

siblings:除此以外的所同級元素；

---------至關於累加；

$("#nei").add("table").add("#f").css("background-color","red");

-----------並把本身也加上；

$("div").find("p").andSelf().addClass("border");

--------------將全部元素添加到b標籤中；

$("#nei").contents().wrap("<b/>");

-------------在p標籤的前面添加標記；append是後面；

$("p").prepend("<b>Hello</b>");

--------------.after,.before,insertafter,insertbefore;

------------將元素包含到另外一元素中；

$("p").wrap(document.getElementById('content'));

------------

將全部匹配的元素用單個元素包裹起來時使用wrapall();

---------------------------:在p的內部添加b;(將b的內容用b抱起來)

$("p").wrapInner("<b></b>");

-----------變換標記；

$("p").click(function () {

$(this).replaceWith("<img src='../img/_8-1.png'></img>");

-----------

});

---------------------複製一份添加到標記中

$("b").clone().prependTo("p");

---------------------

將全部段落的字體顏色設爲紅色而且背景爲藍色。

jQuery 代碼:

$("p").css({ color: "#ff0011", background: "blue" });描述:

若是屬性名包含 "-"的話，必須使用引號:

jQuery 代碼:

$("p").css({ "margin-left": "10px", "background-color": "blue" });

-----------------------無論怎麼樣：鍵值都加雙引號；

$("#f").css({"color":"red","background":"blue"});

----------------------------------------------------------offset相對document的位置；

-----------設定移量；

$("#xuan").offset({top:200,left:400});

-------------獲得相對位置

var a = $("#xuan").offset();

alert(a.left+"----"+a.top);

--------------------------------------------------------------position(),相對於父元素的偏移量；用法和offset同樣；

------blur():失去焦點觸發的事件；

-----change()事件:當內容改變且失去焦點時觸發；

-------------滾動條滾動

$(window).scroll(function () {

setTimeout();

});

-----------序列化操做：

var a = $.parseJSON('{ "name": "guozeng" }');

alert(a.name);

---------------------

------------------------textbox下拉框案例

$(function () {

$("#Text1").focus(function () {

//$("#gg").attr("display","block");

$("#gg").css("display", "block");

$("#gg").offset({ top: $("#Text1").offset().top + $("#Text1").height() + 5, left: $("#Text1").offset().left });

});

$("li").click(function () {

$("#Text1").val($(this).text());

$("#gg").css("display", "none");

});

})

-------------------pannel案例：

$(function () {

$("img[alt='a']").click(function () {

if ($(this).attr("src") == "../img/_8-1.png") {

$(this).attr("src", "../img/_8-2.png")

$("#gg").slideUp(500);

}

else {

$(this).attr("src", "../img/_8-1.png")

$("#gg").slideDown(500);

}

});

})

------------------------------------------------------------------------------------------------------------------

1.new 父類方法：至關於複製了父類的方法，經過比對，不是重寫，因此沒有記錄到方法表的重寫表上。當父類引用指向子類實例時，調用該方法先去重寫表上找，若是沒找到，說明沒被重寫，因此繼續調用父類的方法；

2.繼承，其實是：先將父類複製一份分配內存，在和子類比對，將重寫的方法寫在loader heap的方法表上，當父類指向子類實例，先檢查方法表是否存在重寫方法，沒有的話，繼續調用父

類的。

3,棧：從高位到低位，控件有限，堆，從低位到高位，回收時，不管棧仍是堆，都從低位開始回收，全部就有的先進先出，先進後出之分；

4.進程棧，託管堆：gc堆，存儲屬性，loader heap:存儲方法表、靜態變量;生命週期：appdomain結束（應用程序域結束），當>85K時，存在loh上（large object heap）

5.類的靜態放在loader heap上，先於實例建立。屬性，不管引用仍是值都建立在堆上。方法裏的值建立在進程棧上。值類型中的引用對象的建立，還保持原來同樣，引用在棧，建立在堆上。

-----------------------------------------------

1：無論是重寫仍是覆蓋都不會影響父類自身的功能（廢話，確定的嘛，除非代碼被改）。

2：當用子類建立父類的時候，如 C1 c3 = new C2()，重寫會改變父類的功能，即調用子類的功能；而覆蓋不會，仍然調用父類功能。

3：虛方法、實方法均可以被覆蓋（new），抽象方法，接口不能夠。

4：抽象方法，接口，標記爲virtual的方法能夠被重寫（override），實方法不能夠。

5：重寫使用的頻率比較高，實現多態；覆蓋用的頻率比較低，用於對之前沒法修改的類進行繼承的時候。

----------------

Thread類有幾個相當重要的方法，描述以下：

Start()：啓動線程；

Sleep(int)：靜態方法，暫停當前線程指定的毫秒數；

Abort()：一般使用該方法來終止一個線程；

Suspend()：該方法並不終止未完成的線程，它僅僅掛起線程，之後還可恢復；

Resume()：恢復被Suspend()方法掛起的線程的執行；

------只要是聚合函數就能夠用case when;group by 後面能夠加t-sql函數；

SELECT count(CASE WHEN CContent>4 THEN NULL ELSE 1 END) FROM DailyCheckRecord GROUP BY datepart(year,CDate)

--------------------------

select count(0):查詢結果爲1；

----------------------------------------(1):

[ServiceContract(Name = "name_IUser", Namespace ="http://localhost:3232/wpf/aa")]

-------------------------------------------(2)

[OperationContract(Name = "name_GetName", Action = "http://localhost:3232/wpf/aa/ServiceContract/GetName")]

--------------------------------(3)

using System.Runtime.Serialization;//datacontract；由此而來；須要添加引用的

--------------------李氏替換；不會剖出異常；

//[KnownType(typeof(DataItem.SonDataUser))]；(體現的是一種多態行處理)

------------------------（4）

//isrequired:是否必須初始化；order；序列化時順序；

[DataMember(Name="name_Name",IsRequired=false,Order=0)]

----------------------------------------------------------

object.Equals("0001/1/1 0:00:00", DateTime.MinValue.ToString()

-----------------------------------------------------------------------

property與attribute的區別：

property:有getset;button按鈕的寬度和高度；

attribute:好比：[serializable]

---------------------------------------------------------調用web服務生成成一步操做：必須這樣：（異步調用）

protected void Button1_Click(object sender, EventArgs e)

{

ServiceReference1.WebServiceSoapClient a = new ServiceReference1.WebServiceSoapClient();

a.HellowAsync(new ServiceReference1.HellowRequest(new ServiceReference1.HellowRequestBody(1)));

a.HellowCompleted += new EventHandler<ServiceReference1.HellowCompletedEventArgs>(a_HellowCompleted);

}

public void a_HellowCompleted(object sender, ServiceReference1.HellowCompletedEventArgs e)

{

TextBox1.Text ="sff";

}

------------------同步調用：

ServiceReference1.WebServiceSoapClient a = new ServiceReference1.WebServiceSoapClient();

//ServiceReference1.HellowResponse aa = a.Hellow(new ServiceReference1.HellowRequest(new ServiceReference1.HellowRequestBody(2)));

//MessageBox.Show(aa.Body.HellowResult.ToString());

------------------------------------------------------------------------

if ($("#RadioButton1").attr("checked") ==true) {

alert("郭澤峯呢個");

}

------------------------jquery獲取dropdownlist的值；

alert($("#dropProperty").find('option').filter(':selected').text());

var chec kText=$("#select_id").find("option:selected").text(); //獲取Select選擇的Text

-----------

if ($("#RadioButton1").attr("checked") == true) {

isBid = "是";

}

------------------------js截取字符串；

var param = hrefStr.substring(hrefStr.indexOf('?') + 1, hrefStr.length);

-------------

var aa = $("a[href='/AjaxPaging/UpdataModel/" + hdnId + "']").parent().parent().find("td");

$(aa).slice(0, 1).text(name);

------------------------進程的Process的命名空間（using System.Diagnostics;）意思是診斷的意思；

var ff = new Function("p1", "alert(p1)");

ff(2);

---------------------------

for(var a in arr)

{

alert(a);

}

--------------w3c標準事件；（Ie不支持，其它支持）(注意兩個地方不同；)

document.addEventListener("click", f1);

-------------ie;

document.attachEvent("onclick",f1);

------------

window.event.clientX,clientY;鼠標在文檔的位置；

window.event.screenX,screenY;鼠標在瀏覽器的位置；

window.event.offsetX,offsetY;相對於事件源的位置；

window.event.returnValue=false;取消默認行爲；如提交按鈕不會提交；

----------------取消事件冒泡：

window.event.cancelBubble=true;

-----------動態建立：

window.onload = function () {

var btn = document.createElement("input");

btn.name = "guo";

btn.type = "button";

btn.onclick = function () {

alert("我去你大爺");

};

btn.value = "動態建立";

var dv = document.getElementById("mm");

dv.appendChild(btn);

};

------------document.getelementbyid("").style.background="";

------------

onload與onready的區別：

onload,等documnet和css,js外部文件加載完以後才執行；只能註冊一次；

ready:只等document加載完畢以後才執行；可註冊多此；能夠提升響應速度；

----------

map:對數組遍歷；

each:對字典的遍歷；

---------------------

// $.each(person, function (key, value) {

// alert(key+"--"+value);

> // }, null);

$.each(person, function () {alert(this) });//this，指的是值，由於咱們更對值感興趣；

=--------------\.next("div"):緊鄰的第一個；若是沒挨着；放回空；

-----。end（）,方法返回上一次被破壞的包裝集，好比：$("#id").nextall().end(),指的是$("#id")

$("#id").next().andSelf()//報錯本身和挨着的；

------去掉第一行：

$("#id tr:not(:first)");去掉第一行；

$("#id tr:not(:first):not(:last):even");各行設置；

-----------------全選；

$("#checkall").click(function () {

$(":checkbox[id*=checkbox]").attr("checked", $(this).attr("checked"));

});

---------------------------05594054 0371

---動態建立子元素；

var a=$("<a href='sdf'></a>")

a.css();

a.click();

$().append(a);

----------------remove：會移除對象的事件，但不會移除對象的樣式；

appendto();就至關於剪切粘貼；

----------$("#id").unbind();移除全部的事件；

.one("click",function(){});註冊一次性事件，用完後隨即unbind();若是沒有參數，就卸載全部的事件；

--------------------------------------------

$("#Button1").bind("click", function () {

alert(1);

});

$("#Button1").unbind("click");

-----------------------------------------------切換事件；第一次點擊顯示1，第二次顯示2；

$("#Button1").toggle(function () { alert(1)}, function () { alert(2) });

--------------事件參數能夠防止事件冒泡；

$("#id").click(function(e){

alert("郭");

e.stopPropagetion();

});

這樣在id以外的標籤事件就不會觸發；

$("#id").click(function(e){

alert("郭");

e.preventDefault();//取消控件的默認行爲；與return false;不一樣的是，後續代碼繼續執行；好比取消鏈接的跳轉功能；

alert("則");

});

-------------------

$(document).mousemove(function(e){

$("#di").text(e.pageX+"=="+e.pageY);//獲取文檔的座標；

});

----------

$(document).mousemove(function(e){

$("#di").css({"left":e.pageX,"top":e.pageY});//獲取文檔的座標；

});

-----------------擴展方法：

$.extend({ "max": function (a, b) {

if (a > b)

return a;

}, "min": function () {

if (a < b)

return a;

}

------------------擴展實例方法：

$.fn.extend({"checked":$(this).attr("checked","true")});

$(function () {

alert($.max(55,34));

})

------調用： $("").checked();

----------------------------------

$(window).width();

----------------------cookie:(須要引入cookie.js)

$.cookie("name",value,{expires=10})

----------------------------------frame;

window.parent.afterEdit();

var childWindow = $("#frameEdit")[0].contentWindow; //怎麼來拿frame標籤的一個window對象

childWindow.submitEditFrm();

---------------------數據綁定；gridview;

DataBinder.Eval(Container.DataItem,"Id")

--------------------------------------------------引用樣式表；css嵌套引用另外一個css文件；

@import url(cs1.css);

-------------------------

<asp:UpdatePanel ID="UpdatePanel1" runat="server">

<asp:PostBackTrigger ControlID="btnExport" />

</Triggers>

------------------------------------------必須這樣：

if (!object.Equals(reader["BidDate"], null) && !object.Equals(reader["BidDate"],DBNull.Value))

或

if (!object.Equals(reader["BidDate"], null) &&reader["BidDate"].tostring()!="")

-------------------------------------------------------------------

類的。

3,棧：從高位到低位，控件有限，堆，從低位到高位，回收時，不管棧仍是堆，都從低位開始回收，全部就有的先進先出，先進後出之分；

4.進程棧，託管堆：gc堆，存儲屬性，loader heap:存儲方法表、靜態變量;生命週期：appdomain結束（應用程序域結束），當>85K時，存在loh上（large object heap）

--------------------------存儲過程須要注意：

設置拼接字符串變量@str必須是nvarchar類型，否則會報錯；

返回數量變量必須是：

EXEC sp_executesql @str, N'@num INT OUTPUT', @num OUTPUT

----------------

-----------------

-------------------根據身份證號判斷出生年月和工齡

/// <summary>

/// 出生日期

/// </summary>

public DateTime? Birth

{

get

{

if (_idcard.Length == 18)

{

string birth = _idcard.Substring(6, 8);

return Convert.ToDateTime(birth1);

}

{

public int Age

}

{

string birth = _idcard.Substring(6, 6);

return DateTime.Now.Year - Convert.ToInt32("19" + birth.Substring(0, 2));

}

else

{

return 0;

}

---------------------------------------------存儲過程判斷某一變量是否爲空

if(@PName<>'')

當將語句定義爲字符串時，應將全部變量轉化爲varchar類型，要否則會報錯；

-------

------------------------------好比：

if(@begintime<>'')

set @str=@str+' and ApplyDate>='''+convert(varchar(100),@begintime)+''''

if(@OverTime<>'')

set @str=@str+' and ApplyDate<='''+convert(varchar(100),@OverTime)+''''

---------------------------當有輸出參數執行字符串時；

EXEC sp_executesql @str, N'@num INT OUTPUT', @num OUTPUT

-------------行列轉換

SUM(CASE WHEN T.ParentName=''休假'' THEN T.alldays ELSE 0 END)

--------------------------js根據出生日期獲取年齡；

$(function () {

$("#txtAge").click(function () {

var dateUser = new Date();

var nowYear = dateUser.getFullYear();

var dateUser1 = new Date($("#txtBirthDate").val());

var birthYear = dateUser1.getFullYear();

$("#txtAge").val(nowYear - birthYear);

if ($("#txtAge").val() > 18) {

alert("年齡超過18歲，禁止填寫");

}

});

---------------------彙總模板：

------彙總數據

select a.id,a.PerId,a.allworkm,a.allrestm,a.allvalm,a.workdays,a.restdays,a.valmdays,a.alldays,a.allmoney,
