[SQL]使用SQL查询表中不存在的ID

自增表

 

USE [li]
GO
/****** 对象:  Table [dbo].[IDArray]    脚本日期: 05/11/2012 08:26:46 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE TABLE [dbo].[IDArray](
    [id] [int] NOT NULL,
 CONSTRAINT [PK_IDArray] PRIMARY KEY CLUSTERED
(
    [id] ASC
)WITH (PAD_INDEX  = OFF, STATISTICS_NORECOMPUTE  = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS  = ON, ALLOW_PAGE_LOCKS  = ON) ON [PRIMARY]
) ON [PRIMARY]

 

结果表

 

USE [li]
GO
/****** 对象:  Table [dbo].[ResultRecord]    脚本日期: 05/11/2012 08:27:25 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE TABLE [dbo].[ResultRecord](
    [ID] [int] IDENTITY(1,1) NOT NULL,
    [ResultID] [int] NULL,
    [TableType] [nvarchar](40) NULL,
    [Keyword] [nvarchar](100) NULL,
    [KeywordType] [nvarchar](50) NULL,
 CONSTRAINT [pk_ResultRecord] PRIMARY KEY CLUSTERED
(
    [ID] ASC
)WITH (PAD_INDEX  = OFF, STATISTICS_NORECOMPUTE  = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS  = ON, ALLOW_PAGE_LOCKS  = ON) ON [PRIMARY]
) ON [PRIMARY]

查询的存储过程

 

USE [li]
GO
/****** 对象:  StoredProcedure [dbo].[CheckNoExist]    脚本日期: 05/11/2012 08:27:55 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
ALTER Procedure [dbo].[CheckNoExist]
@Column varchar(50)='',
@Table varchar(50)='',
@Url varchar(200)=''
As
Set NoCount on

Declare @ID int,@Number int,@IsEqual int
exec('Declare IDCursor Cursor  For Select top 1 '+@Column+' from '+@Table+' With(Nolock) Order by '+@Column+' desc')
Open IDCursor
set @Number=1
Fetch Next From IDCursor Into @ID

----填充自增循环表---------------------
if exists (select id from IDArray)
    exec('delete from IDArray')



While @ID>=@Number
Begin
    Insert IDArray(ID) values(''+@Number+'')
    set @Number=@Number+1
End

----对比ID---------------------------
exec('Insert UrlRecord(id,tname,url) select id,'''+@Table+''',REPLACE(REPLACE('''+@Url+''',''{ID}'',id),''{DIR}'',id/1000) from IDArray where id not in(select '+@Column+' from '+@Table+')')

Close IDCursor
deallocate IDCursor

存储过程调用示例

 

EXEC CheckNoExist agent_info_id,'cnsbdata.dbo.agent_info','html/agent/{DIR}/agent_info_show_{ID}.html';
