规范化的SQL数据修改语句总结

这篇文章主要为大家详细介绍了规范化的SQL数据修改语句总结，具有一定的参考价值，可以用来参考一下。

对此感兴趣的朋友，看看idc笔记做的技术笔记！

代码如下:

 
IF NOT EXISTS (SELECT * FROM SYSCOLUMNS WHERE ID=OBJECT_ID('QueryDataSource') and name = 'IsCrossTable') 
BEGIN 
ALTER TABLE QueryDataSource ADD IsCrossTable bit default(0) --插入字段 
END 

代码如下:

 
if exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[PLSystem_Insert]') and OBJECTPROPERTY(id, N'IsProcedure') = 1) 
drop procedure [dbo].[PLSystem_Insert] 
go 
CREATE PROCEDURE dbo.PLSystem_Insert 
( 
@PLSystemID smallint, 
@PLSystemName varchar(20), 
@PLSystemFlag char(2) 
) 
AS 
INSERT INTO dbo.PLSystem 
( 
PLSystemID, 
PLSystemName, 
PLSystemFlag 
) 
VALUES 
( 
@PLSystemID, 
@PLSystemName, 
@PLSystemFlag 
) 
go 

if exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[PLSystem_Delete]') and OBJECTPROPERTY(id, N'IsProcedure') = 1) 
drop procedure [dbo].[PLSystem_Delete] 
go 
CREATE PROCEDURE dbo.PLSystem_Delete 
( 
@PLSystemID smallint 
) 
AS 
DELETE FROM dbo.PLSystem 
WHERE 
PLSystemID = @PLSystemID 
go 

if exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[PLSystem_Update]') and OBJECTPROPERTY(id, N'IsProcedure') = 1) 
drop procedure [dbo].[PLSystem_Update] 
go 
CREATE PROCEDURE dbo.PLSystem_Update 
( 
@PLSystemID smallint, 
@PLSystemName varchar(20), 
@PLSystemFlag char(2) 
) 
AS 
UPDATE dbo.PLSystem SET 
PLSystemName = @PLSystemName, 
PLSystemFlag = @PLSystemFlag 
WHERE 
PLSystemID = @PLSystemID 
go 

代码如下:

 
IF EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N'[dbo].[PLSystem]') AND type in (N'U')) 
DROP TABLE [dbo].[PLSystem] 
GO 
IF NOT EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N'[dbo].[PLSystem]') AND type in (N'U')) 
BEGIN 
CREATE TABLE [dbo].[PLSystem]( 
[PLSystemID] [tinyint] NOT NULL, 
[PLSystemName] [varchar](20) NULL, 
[PLSystemFlag] [char](2) NULL, 
CONSTRAINT [XPKPLSystem] PRIMARY KEY CLUSTERED 
( 
[PLSystemID] ASC 
) 
) ON [PRIMARY] 
END 
GO 

代码如下:

 
Begin 
declare @PluserID varchar(8) 
declare pluserCurse Cursor for select PLUserID from PLUser where PCancelJudge=0 
open pluserCurse --打开游标 
fetch next from pluserCurse into @PluserID 
while @@FETCH_STATUS=0 
begin 
print (@PluserID) 
insert into PLUserActorDepart(DepartID,PLActorSystemID,PLUserID) 
select DepartmentID,PLSystemID,PLUserID from MSUserRight where MSUserRight.DepartmentID not in 
( 
select DepartmentID from PLDepartment where PLDepartment.DParent=(select DepartmentID from PLUser where PLUserID=@PluserID ) 
OR PLDepartment.DepartmentID=(select DepartmentID from PLUser where PLUserID =@PluserID) 
) AND MSUserRight.PLUserID=@PluserID 
fetch next from pluserCurse into @PluserID 
end 
close pluserCurse 
deallocate pluserCurse 
end 

代码如下:

 
Create Proc InsertSQL 
AS 
Begin 
DECLARE @Count int 
set @Count=0; 
While(@Count<200000) 
Begin 
Print(@Count); 
Insert into Student values('YOUNG','M',100,'FUJIANXIAMENT'); 
set @Count=@Count+1; 
END 
END
