alter table dbo.JiuHuo_User add ss varchar(50) alter table JiuHuo_User alter column ss ss1 varchar(50) exec sp_rename 'JiuHuo_User','ss','ss1','column' exec sp_rename 'JiuHuo_User.ss','addr' alter table JiuHuo_User alter column addr int alter table JiuHuo_User drop column addr exec sp_rename 'JiuHuo_User','JiuHuo_User' alter table JiuHuo_User sp_rename JiuHuo_User1 alter table dbo.JiuHuo_User add sss int IDENTITY(100000,1) alter table JiuHuo_User alter column ss int IDENTITY(1,1) select * from [user] update [user] set city='000000000000'
