SQL Server存儲(chǔ)過(guò)程創(chuàng)建和修改打開SQL Server 2005的管理工具，選中需要?jiǎng)?chuàng)建存儲(chǔ)過(guò)程的數(shù)據(jù)庫(kù)，找到“可編程性”，展開后可以看到“存儲(chǔ)過(guò)程”。右鍵點(diǎn)擊它，選擇“新建存儲(chǔ)過(guò)程”，右側(cè)的編輯窗口打開了，里面裝著微軟自動(dòng)生成的SQL Server創(chuàng)建存儲(chǔ)過(guò)程的語(yǔ)句。
1 CREATE PROCEDURE Get_Data 2 ( 3 @Dealer_ID VARCHAR(50) 4 ) 5 AS 6 SELECT * FROM myData WHERE Dealer_ID = @Dealer_ID 既然創(chuàng)建存儲(chǔ)過(guò)程已經(jīng)會(huì)了，那么修改還會(huì)難嗎？顯然不會(huì)。修改存儲(chǔ)過(guò)程也是相當(dāng)?shù)娜菀?。首先，刷新?dāng)前數(shù)據(jù)庫(kù)的存儲(chǔ)過(guò)程列表，這時(shí)就能看到你剛創(chuàng)建的存儲(chǔ)過(guò)程的名字了，右鍵點(diǎn)擊它，選擇修改，右側(cè)又打開了一個(gè)編輯窗口，裝著的就是修改存儲(chǔ)過(guò)程的代碼（如下） 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(jiǎn)單的修改下吧，代碼如下  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(zhí)行，修改存儲(chǔ)過(guò)程完成。 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，創(chuàng)建成功，調(diào)用它插入數(shù)據(jù)，OK，沒(méi)問(wèn)題插入成功，達(dá)到了預(yù)期的目的 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： 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 |
