SQL语句实现取消自增列属性
1、如果仅仅是指定值插入,可用以下语句,临时取消
SET IDENTITY_INSERT TableName ON
INSERT INTO tableName(xx,xx) values(xx,xx)
SET IDENTITY_INSERT TableName OFF
2、新增一列,删除自增列,修改改列名
alter table a add xxx int
update a set xxx=id
alter table a drop column id
exec sp_rename 'xxx', 'id', 'column'
3、通过修改系统关于该表的列属性,该方法使用不当将可能引起其它不可预料的错误
sp_configure 'allow update',1
reconfigure with override
go
update syscolumns set colstat=0 where colstat=1 and id=object_id('tablename')
go
sp_configure 'allow update',0
reconfigure with override
