SQL2000中指定位置插入列的处理方法：

系统的处理很简单，建一个新表Tmp_test，把旧表test的数据全部插入到新表中，然后删除test，把Tmp_test改名为test，代码如下:

BEGIN TRANSACTION

SET QUOTED_IDENTIFIER ON

SET ARITHABORT ON

SET NUMERIC_ROUNDABORT OFF

SET CONCAT_NULL_YIELDS_NULL ON

SET ANSI_NULLS ON

SET ANSI_PADDING ON

SET ANSI_WARNINGS ON

COMMIT

BEGIN TRANSACTION

CREATE TABLE dbo.Tmp_test

(

a char(10) NULL,

b char(10) NULL,

c char(10) NULL,

d char(10) NULL

) ON [PRIMARY]

GO

IF EXISTS(SELECT * FROM dbo.test)

EXEC('INSERT INTO dbo.Tmp_test (a, c, d)

SELECT a, c, d FROM dbo.test (HOLDLOCK TABLOCKX)')

GO

DROP TABLE dbo.test

GO

EXECUTE sp_rename N'dbo.Tmp_test', N'test', 'OBJECT'

GO

COMMIT
