关于sql 中导入数据时的自动增长列转换为一般列，导入后转换为自动增长列

if exists (select * from sysobjects where id = OBJECT_ID('[d_dbInfo]') and OBJECTPROPERTY(id, 'IsUserTable') = 1)

DROP TABLE [d_dbInfo] //判断该表是否已存在 ，存在 删除

//建表

CREATE TABLE [d_dbInfo] (

[id] [int] IDENTITY (1, 1) NOT NULL,

[d_dbname] [nvarchar] (32) NULL,

[d_time] [datetime] NULL)

//

ALTER TABLE [d_dbInfo] WITH NOCHECK ADD CONSTRAINT [PK_d_dbInfo] PRIMARY KEY NONCLUSTERED ( [id] )

//设置自动增长列关闭

SET IDENTITY_INSERT [d_dbInfo] ON

INSERT [d_dbInfo] ([id],[d_dbname],[d_time]) VALUES ( 1,'DB20110916184056.bak','2011-9-16 18:40:56')

//使用自动增长列

SET IDENTITY_INSERT [d_dbInfo] OFF
