標籤開源 sqlserver orm 框架 sqlsugar 3.0 api 欄目 SqlServer 简体版

原文原文鏈接

3.1.x ,將做爲3.X系統的最後一個版本，下面將會開發全新的功能

更新列表：https://github.com/sunkaixuan/SqlSugar/releaseshtml

優勢：

SqlSugar 是一款小巧，而且功能齊全的ORM，並不須要像Dapper同樣依賴第三方擴展git

SqlSugar 語法易用簡單，有漂亮的拉姆達語法，也支持Dapper SQL和ADO.NET的全部功能github

SqlSugar 性能達到原生水準，遠超 Dapper和EF CORE。sql

SqlSugar 支持.NET CORE , 多個數據庫數據庫

SqlSugar 體積小巧只有150K是EF的30分之1 ，NUGET直接能夠下載json

特點功能

SqlbulkCopy和SqlbulkReplace 這兩個函數可以處理海量數據插入和更新，也是衆多ORM沒有集成的功能之一數組

SQL日誌功能能夠方便的對SQL進行監控和寫入日誌緩存

全局過濾器例如我都有IsDeleted來標識是否刪除，這樣我每查一個表就要加一個WHERE條件，有了全局過濾器就變成很是方便cookie

T4+實體生成能夠自定義實體格式而且能夠能過T4模版快速生成實體文件session

POCO設計實體類沒有任何屬性徹底原生態

全部版本：

ASP.NET 4.0+ MSSQL https://github.com/sunkaixuan/SqlSugar

ASP.NET CORE MSSQL https://github.com/sunkaixuan/ASP_NET_CORE_ORM_SqlSugar

ASP.NET 4.0+ MYSQL https://github.com/sunkaixuan/MySqlSugar

ASP.NET CORE MYSQL https://github.com/sunkaixuan/ASP_NET_CORE_ORM_MySqlSugar

ASP.NET 4.0+ Sqlite https://github.com/sunkaixuan/SqliteSugar

ASP.NET CORE Sqlite https://github.com/sunkaixuan/ASP_NET_CORE_ORM_MySqlSugar

ASP.NET 4.0+ ORACLE https://github.com/sunkaixuan/OracleSugar

鏈接數據庫

1.簡單用法

using(var db = new SqlSugarClient(ConnectionString)){

    //use object
    var list=db.Queryable<T>().ToList(); }

2.打包用法，推薦

/// <summary>
/// SqlSugar
/// </summary>
public class SugarDao
{
    private SugarDao() { } public static string ConnectionString { get { string reval = "server=.;uid=sa;pwd=sasa;database=SqlSugarTest"; return reval; } } public static SqlSugarClient GetInstance() { var db = new SqlSugarClient(ConnectionString); db.IsEnableLogEvent = true;//Enable log events db.LogEventStarting = (sql, par) => { Console.WriteLine(sql + " " + par+"\r\n"); }; return db; } }

使用打包對象

using (var db = SugarDao.GetInstance())
{
    var list=db.Queryable<T>().ToList(); }

3.高級玩法，基於IOC和指揮官模式的DEMO

一、使用拉姆達進行查詢

                //查詢全部
                var student = db.Queryable<Student>().ToList();
                var studentDynamic = db.Queryable<Student>().ToDynamic();
                var studentJson = db.Queryable<Student>().ToJson();


                //查詢單條
                var single = db.Queryable<Student>().Single(c => c.id == 1);
                //查詢單條根據主鍵
                var singleByPk = db.Queryable<Student>().InSingle(1);
                //查詢單條沒有記錄返回空對象
                var singleOrDefault = db.Queryable<Student>().SingleOrDefault(c => c.id == 11111111);
                //查詢單條沒有記錄返回空對象
                var single2 = db.Queryable<Student>().Where(c => c.id == 1).SingleOrDefault();

                //查詢第一條
                var first = db.Queryable<Student>().Where(c => c.id == 1).First();
                var first2 = db.Queryable<Student>().Where(c => c.id == 1).FirstOrDefault();

                //取11-20條
                var page1 = db.Queryable<Student>().Where(c => c.id > 10).OrderBy(it => it.id).Skip(10).Take(10).ToList();

                //取11-20條  等於 Skip(pageIndex-1)*pageSize).Take(pageSize) 等於  between (pageIndex-1)*pageSize and  pageIndex*pageSize
                var page2 = db.Queryable<Student>().Where(c => c.id > 10).OrderBy(it => it.id).ToPageList(2, 10);

                //查詢條數
                var count = db.Queryable<Student>().Where(c => c.id > 10).Count();

                //從第2條開始之後取全部
                var skip = db.Queryable<Student>().Where(c => c.id > 10).OrderBy(it => it.id).Skip(2).ToList();

                //取前2條
                var take = db.Queryable<Student>().Where(c => c.id > 10).OrderBy(it => it.id).Take(2).ToList();

                //Not like 
                string conval = "a";
                var notLike = db.Queryable<Student>().Where(c => !c.name.Contains(conval.ToString())).ToList();

                //Like
                conval = "三";
                var like = db.Queryable<Student>().Where(c => c.name.Contains(conval)).ToList();

                //支持字符串Where 讓你解決，更復雜的查詢
                var student12 = db.Queryable<Student>().Where(c => "a" == "a").Where("id>@id", new { id = 1 }).ToList();
                var student13 = db.Queryable<Student>().Where(c => "a" == "a").Where("id>100 and id in( select 1)").ToList();


                //存在記錄反回true，則否返回false
                bool isAny100 = db.Queryable<Student>().Any(c => c.id == 100);
                bool isAny1 = db.Queryable<Student>().Any(c => c.id == 1);


                //獲取最大Id
                object maxId = db.Queryable<Student>().Max(it => it.id);
                int maxId1 = db.Queryable<Student>().Max(it => it.id).ObjToInt();//拉姆達
                int maxId2 = db.Queryable<Student>().Max<int>("id"); //字符串寫法

                //獲取最小
                int minId1 = db.Queryable<Student>().Where(c => c.id > 0).Min(it => it.id).ObjToInt();//拉姆達
                int minId2 = db.Queryable<Student>().Where(c => c.id > 0).Min<int>("id");//字符串寫法


                //order By 
                var orderList = db.Queryable<Student>().OrderBy("id desc,name asc").ToList();//字符串支持多個排序
                //能夠多個order by表達示
                var order2List = db.Queryable<Student>().OrderBy(it => it.name).OrderBy(it => it.id, OrderByType.desc).ToList(); // order by name as ,order by id desc

                //In
                var intArray = new[] { "5", "2", "3" };
                var intList = intArray.ToList();
                var listnew = db.Queryable<Student>().Where(it => intArray.Contains(it.name)).ToList();
                var list0 = db.Queryable<Student>().In(it => it.id, 1, 2, 3).ToList();
                var list1 = db.Queryable<Student>().In(it => it.id, intArray).ToList();
                var list2 = db.Queryable<Student>().In("id", intArray).ToList();
                var list3 = db.Queryable<Student>().In(it => it.id, intList).ToList();
                var list4 = db.Queryable<Student>().In("id", intList).ToList();
                var list6 = db.Queryable<Student>().In(intList).ToList();//不設置字段默認主鍵

                //分組查詢
                var list7 = db.Queryable<Student>().Where(c => c.id < 20).GroupBy(it => it.sex).Select("sex,count(*) Count").ToDynamic();

                var time2 = db.Queryable<InsertTest>().Where(c => c.d1 > DateTime.Now.AddYears(1)).ToList();
                var time3 = db.Queryable<InsertTest>().Where(c => c.d1 > DateTime.Now.AddMonths(1)).ToList();

二、使用原生SQL查詢

                //轉成list
                List<Student> list1 = db.SqlQuery<Student>("select * from Student");
                //轉成list帶參
                List<Student> list2 = db.SqlQuery<Student>("select * from Student where id=@id", new { id = 1 });
                //轉成dynamic
                dynamic list3 = db.SqlQueryDynamic("select * from student");
                //轉成json
                string list4 = db.SqlQueryJson("select * from student");
                //返回int
                var list5 = db.SqlQuery<int>("select top 1 id from Student").SingleOrDefault();
                //反回鍵值
                Dictionary<string, string> list6 = db.SqlQuery<KeyValuePair<string, string>>("select id,name from Student").ToDictionary(it => it.Key, it => it.Value);
                //反回List<string[]>
                var list7 = db.SqlQuery<string[]>("select top 1 id,name from Student").SingleOrDefault();
                //存儲過程
                var spResult = db.SqlQuery<School>("exec sp_school @p1,@p2", new { p1 = 1, p2 = 2 });

                //存儲過程加Output 
                var pars = SqlSugarTool.GetParameters(new { p1 = 1,p2=0 }); //將匿名對象轉成SqlParameter
                db.IsClearParameters = false;//禁止清除參數
                pars[1].Direction = ParameterDirection.Output; //將p2設爲 output
                var spResult2 = db.SqlQuery<School>("exec sp_school @p1,@p2 output", pars);
                db.IsClearParameters = true;//啓動請動清除參數
                var outPutValue = pars[1].Value;//獲取output @p2的值

                //獲取第一行第一列的值
                string v1 = db.GetString("select '張三' as name");
                int v2 = db.GetInt("select 1 as name");
                double v3 = db.GetDouble("select 1 as name");
                decimal v4 = db.GetDecimal("select 1 as name");

三、SQL高級拼接器寫法

 using (var db = SugarDao.GetInstance())
            {
                //---------Sqlable,建立多表查詢---------//

                //多表查詢
                List<School> dataList = db.Sqlable()
                   .From("school", "s")
                   .Join("student", "st", "st.id", "s.id", JoinType.INNER)
                   .Join("student", "st2", "st2.id", "st.id", JoinType.LEFT)
                   .Where("s.id>100 and s.id<@id")
                   .Where("1=1")//能夠多個WHERE
                   .OrderBy("id")
                   .SelectToList<School/*新的Model我這裏沒有因此寫的School*/>("st.*", new { id = 1 });

                //多表分頁
                List<School> dataPageList = db.Sqlable()
                    .From("school", "s")
                    .Join("student", "st", "st.id", "s.id", JoinType.INNER)
                    .Join("student", "st2", "st2.id", "st.id", JoinType.LEFT)
                    .Where("s.id>100 and s.id<100")
                    .SelectToPageList<School>("st.*", "s.id", 1, 10);

                //多表分頁WHERE加子查詢
                List<School> dataPageList2 = db.Sqlable()
                    .From("school", "s")
                    .Join("student", "st", "st.id", "s.id", JoinType.INNER)
                    .Join("student", "st2", "st2.id", "st.id", JoinType.LEFT)
                    .Where("s.id>100 and s.id<100 and s.id in (select 1 )" /*這裏面寫子查詢均可以*/)
                    .SelectToPageList<School>("st.*", "s.id", 1, 10);



                //--------轉成List Dynmaic 或者 Json-----//

                //不分頁
                var list1 = db.Sqlable().From("student", "s").Join("school", "l", "s.sch_id", "l.id and l.id=@id", JoinType.INNER).SelectToDynamic("*", new { id = 1 });
                var list2 = db.Sqlable().From("student", "s").Join("school", "l", "s.sch_id", "l.id and l.id=@id", JoinType.INNER).SelectToJson("*", new { id = 1 });
                var list3 = db.Sqlable().From("student", "s").Join("school", "l", "s.sch_id", "l.id and l.id=@id", JoinType.INNER).SelectToDataTable("*", new { id = 1 });

                //分頁
                var list4 = db.Sqlable().From("student", "s").Join("school", "l", "s.sch_id", "l.id and l.id=@id", JoinType.INNER).SelectToPageDynamic("s.*", "l.id", 1, 10, new { id = 1 });
                var list5 = db.Sqlable().From("student", "s").Join("school", "l", "s.sch_id", "l.id and l.id=@id", JoinType.INNER).SelectToPageTable("s.*", "l.id", 1, 10, new { id = 1 });
                var list6 = db.Sqlable().From("student", "s").Join("school", "l", "s.sch_id", "l.id and l.id=@id", JoinType.INNER).SelectToPageDynamic("s.*", "l.id", 1, 10, new { id = 1 });


                //--------拼接-----//
                Sqlable sable = db.Sqlable().From<Student>("s").Join<School>("l", "s.sch_id", "l.id", JoinType.INNER);
                string name = "a";
                int id = 1;
                if (!string.IsNullOrEmpty(name))
                {
                    sable = sable.Where("s.name=@name");
                }
                if (!string.IsNullOrEmpty(name))
                {
                    sable = sable.Where("s.id=@id or s.id=100");
                }
                if (id > 0)
                {
                    sable = sable.Where("l.id in (select top 10 id from school)");//where加子查詢
                }
                var pars = new { id = id, name = name };
                int pageCount = sable.Count(pars);
                var list7 = sable.SelectToPageList<Student>("s.*", "l.id desc", 1, 20, pars);


            }

四、更新

                //指定列更新
                db.Update<School>(new { name = "藍翔14" }, it => it.id == 14); //只更新name列
                db.Update<School, int>(new { name = "藍翔11 23 12", areaId = 2 }, 11, 23, 12);
                db.Update<School, string>(new { name = "藍翔2" }, new string[] { "11", "21" });
                db.Update<School>(new { name = "藍翔2" }, it => it.id == 100);



                //支持字典更新，適合動態權限
                var dic = new Dictionary<string, string>();
                dic.Add("name", "第十三條");
                dic.Add("areaId", "1");
                db.Update<School, int>(dic, 13);


                //整個實體更新
                db.Update(new School { id = 16, name = "藍翔16", AreaId = 1 });
                db.Update<School>(new School { id = 12, name = "藍翔12", AreaId = 2 }, it => it.id == 18);
                db.Update<School>(new School() { id = 11, name = "青鳥11" });

                //設置不更新列
                db.DisableUpdateColumns = new string[] { "CreateTime" };//設置CreateTime不更新

                TestUpdateColumns updObj = new TestUpdateColumns()
                {
                    VGUID = Guid.Parse("542b5a27-6984-47c7-a8ee-359e483c8470"),
                    Name = "xx",
                    Name2 = "xx2",
                    IdentityField = 0,
                    CreateTime = null
                };

                //CreateTime將不會被更新
                db.Update(updObj);
                //之前實現這種更新須要用指定列的方式實現，如今就簡單多了。



                //批量更新   數據量小時建議使用
                var updateResult = db.UpdateRange(GetUpdateList());

                //批量更新  數據量大時建議使用
                var updateResult2 = db.SqlBulkReplace(GetUpdateList2());

五、刪除和狀態刪除

               //刪除
                db.Delete<School, int>(10);
                db.Delete<School>(it => it.id > 100);
                //主鍵批量刪除
                db.Delete<School, string>(new string[] { "100", "101", "102" });
                //非主鍵批量刪除
                db.Delete<School, string>(it => it.name, new string[] { "" });
                db.Delete<School, int>(it => it.id, new int[] { 20, 22 });

                //假刪除
                //db.FalseDelete<school>("is_del", 100);
                //等同於 update school set is_del=1 where id in(100)
                //db.FalseDelete<school>("is_del", it=>it.id==100);

六、插入

                db.Insert(GetInsertItem()); //插入一條記錄 (有主鍵也好，沒主鍵也好，有自增列也好均可以插進去)


                db.InsertRange(GetInsertList()); //批量插入 支持（別名表等功能）


                db.SqlBulkCopy(GetInsertList()); //批量插入 適合海量數據插入，要求實體與數據庫一致，不支持(別名表、排除列等功能)



                //設置不插入列
                db.DisableInsertColumns = new string[] { "sex" };//sex列將不會插入值
                Student s = new Student()
                {
                    name = "張" + new Random().Next(1, int.MaxValue),
                    sex = "gril"
                };
                var id = db.Insert(s); //插入
                //查詢剛插入的sex是否有值
                var sex = db.Queryable<Student>().Single(it => it.id == id.ObjToInt()).sex;//無值
                var name = db.Queryable<Student>().Single(it => it.id == id.ObjToInt()).name;//有值

七、枚舉支持

  var stuList = db.Queryable<Student>().ToList();
                db.Insert<Student>(new Student() { sch_id = SchoolEnum.北大青鳥 });
                db.Update<Student>(new Student() { sch_id = SchoolEnum.it清華, id = 11 });
                var stuList2 = db.Queryable<Student>().Where(it => it.sch_id == SchoolEnum.全智).ToList();

八、實體生成加T4

 //能夠結合別名表，請看別名表的用法
                //db.SetMappingTables(mappingTableList);

                db.ClassGenerating.CreateClassFiles(db, ("e:/TestModels"), "Models");

                //只生成student和school表的實體
                db.ClassGenerating.CreateClassFilesByTableNames(db, "e:/TestModels2", "Models", new string[] { "student", "school" });

                //根據表名生成class字符串
                var str = db.ClassGenerating.TableNameToClass(db, "Student");

                var dynamicToClassStr = db.ClassGenerating.DynamicToClass(new { id = 1 }, "dyName");

                //根據SQL語句生成class字符串
                var str2 = db.ClassGenerating.SqlToClass(db, "select top 1 * from Student", "student");

                //改變值（lassTemplate.ItemTemplate=XXXX）能夠自定義格式
                var tempItem = ClassTemplate.ItemTemplate;//例如能夠在生成的實體添加默認構造函數給指定的字段賦默認值或者公司信息等
                var temp = ClassTemplate.Template;



                //設置新格式模板
                //主鍵Guid.New(),
                //CreateTime爲DateTime.Now 
                //IsRemove=0
                //UpdateTime爲DateTime.Now 
                ClassTemplate.Template = "using System;\r\nusing System.Linq;\r\nusing System.Text;\r\n\r\nnamespace $namespace\r\n{\r\n    public class $className\r\n    {\r\n        public $className() \r\n        { \r\n            this.CreateTime = DateTime.Now;\r\n            this.  = 0;\r\n            this.UpdateTime=DateTime.Now;\r\n            this.$primaryKeyName=Guid.NewGuid().ToString(\"N\").ToUpper();\r\n        }\r\n        $foreach\r\n    }\r\n}\r\n";

                //新格式的實體字符串
                var str3 = db.ClassGenerating.TableNameToClass(db, "Student");

九、ADO.NET

  var r1 = db.GetDataTable("select * from student");
                var r2 = db.GetSingle<Student>("select top 1 * from student");
                var r3 = db.GetScalar("select  count(1) from student");
                var r4 = db.GetReader("select  count(1) from student");
                r4.Dispose();
                var r5 = db.GetString("select  top 1 name from student");
                var r6 = db.ExecuteCommand("select 1");


                //參數支持
                var p1 = db.GetDataTable("select * from student where id=@id", new {id=1 });
                var p2 = db.GetDataTable("select * from student where id=@id", new Dictionary<string, object>() { { "id", "1" } });//目前只支持 Dictionary<string, object>和Dictionary<string, string>
                var p3 = db.GetDataTable("select * from student where id=@id", new SqlParameter("@id",1) );

                {
                    //日誌記錄件事件裏面用到數據庫操做 IsEnableLogEvent必定要爲false不然將引發死循環，而且要新開一個數據實例 像我這樣寫就沒問題。
                    db.IsEnableLogEvent = false;
                    db.ExecuteCommand("select 1");
