SQL Server存儲過程建立和修改

打開SQL Server 2005的管理工具,選中須要建立存儲過程的數據庫,找到「可編程性」,展開後能夠看到「存儲過程」。右鍵點擊它,選擇「新建存儲過程」,右側的編輯窗口打開了,裏面裝着微軟自動生成的SQL Server建立存儲過程的語句。html


將存儲過程的名字,參數,操做語句寫好後,點擊語法分析,沒有錯誤就直接「F5」運行就行了,存儲過程建立完畢,如下是一個基本的存儲過程的代碼:sql

1 CREATE PROCEDURE Get_Data    
2    (    
3        @Dealer_ID VARCHAR(50)   
4     )    
5     AS    
6 SELECT * FROM myData WHERE Dealer_ID = @Dealer_ID

點擊查看實際例子數據庫

既然建立存儲過程已經會了,那麼修改還會難嗎?顯然不會。修改存儲過程也是至關的容易。首先,刷新當前數據庫的存儲過程列表,這時就能看到你剛建立的存儲過程的名字了,右鍵點擊它,選擇修改,右側又打開了一個編輯窗口,裝着的就是修改存儲過程的代碼(以下)編程

1 ALTER PROCEDURE [dbo].[Get_Data]    
2    (    
3        @Dealer_ID VARCHAR(50)   
4     )    
5     AS    
6 SELECT * FROM myData WHERE Dealer_ID = @Dealer_ID

簡單的修改下吧,代碼以下工具

1  ALTER PROCEDURE [dbo].[Get_Data]    
2    (    
3        @Dealer_ID VARCHAR(50),
4        @Period VARCHAR(20)
5     )    
6     AS    
7     SELECT * FROM myData WHERE Dealer_ID = @Dealer_ID AND Period = @Period

F5 成功執行,修改存儲過程完成。

開始寫了一個存儲過程,用來實現數據的插入操做,說白了就是添加數據。這個存儲過程的代碼以下:sqlserver

 1 CREATE PROCEDURE PROC_INSERT_DATA_ID
 2   @DealerID varchar(50)
 3 AS
 4 BEGIN
 5         DECLARE @COUNT  INT    
 6         
 7         SET @COUNT = (SELECT COUNT(*) FROM myDATA_Details WHERE DealerID = @DealerID)
 8         IF (@COUNT>0)    
 9             BEGIN    
10                 DELETE FROM myDATA_Details WHERE DealerID = @DealerID    
11                 INSERT INTO myDATA_Details (DealerID) VALUES (@DealerID)    
12             END    
13         ELSE    
14             BEGIN    
15                 INSERT INTO myDATA_Details (DealerID) VALUES (@DealerID)    
16             END    
17     END

F5一下,建立成功,調用它插入數據,OK,沒問題插入成功,達到了預期的目的
用於更新數據,代碼以下:url

 1 CREATE PROCEDURE PROC_INSERT_DATA_DETAIL
 2         @DealerID varchar(50), 
 3         @FieldName varchar(2000),
 4         @FieldValue varchar(2000)
 5     AS
 6     BEGIN
 7         DECLARE @Count INT
 8         SET @Count = (SELECT COUNT(*) FROM myDATA_Details WHERE DealerID = @DealerID)
 9 
10         IF (@COUNT>0)
11             BEGIN
12                 UPDATE myDATA_Details SET DealValue = @FieldValue WHERE DealerID = @DealerID
13             END
14         ELSE
15             BEGIN
16                 INSERT INTO myDATA_Details (DealerID) VALUES (@DealerID)
17              END
18     END

或者:
修改後的代碼spa

 1 ALTER PROCEDURE PROC_INSERT_DATA_DETAIL
 2         @DealerID varchar(50), 
 3         @FieldName varchar(2000),
 4         @FieldValue varchar(2000)
 5     AS
 6     BEGIN
 7         DECLARE @Count INT
 8         DECLARE @StrSQL VARCHAR(2000)
 9         SET @Count = (SELECT COUNT(*) FROM myDATA_Details WHERE DealerID = @DealerID)
10 
11         IF (@COUNT>0)
12             BEGIN
13                 SET @StrSQL = 'UPDATE myDATA_Details SET '+ @FieldName + ' = ''' +@FieldValue + ''' WHERE DealerID = '+ @DealerID
14                 EXEC(@StrSQL)
15             END
16         ELSE
17             BEGIN
18                 INSERT INTO myDATA_Details (DealerID) VALUES (@DealerID)
19                 SET @StrSQL = 'UPDATE myDATA_Details SET '+ @FieldName + ' = ''' +@FieldValue + ''' WHERE DealerID = '+ @DealerID
20                 EXEC(@StrSQL)
21             END
22     END
