SQL server 2000 如何判断临时表是否存在 .

1.判断一个临时表是否存在

if exists (select * from tempdb.dbo.sysobjects where id = object_id(N'tempdb..#tempcitys') and type='U')

drop table #tempcitys

注意tempdb后面是两个. 不是一个的

---临时表

if exists(select * from tempdb..sysobjects where name like ‘#tmp1%‘)

drop table #tmp1

或

if exists( select * from tempdb..sysobjects where id=OBJECT_ID('tempdb..#tmp') )

drop table #tmp1

--视图

if exists (select * from sysobjects where id = object_id(N‘[dbo].[ESTMP]‘)

and OBJECTPROPERTY(id, N‘IsView‘) = 1)

drop view ESTMP

判断表是否存在

if exists (select * from sysobjects where id = object_id(N'[dbo].[phone]') and OBJECTPROPERTY(id, N'IsUserTable') = 1)

drop table [dbo].[phone]
