sqlserver中判断表或临时表是否存在
1、判断数据表是否存在 方法一: use yourdb; go if object_id(N'tablename',N'U') is not null print '存在' else print '不存在' 例如: use fireweb; go if object_id(N'TEMP_TBL',N'U') is not null print '存在' else print '不存在' 方法二: USE [实例名] GO IF EXISTS (SELECT * FROM dbo.SysObjects WHERE ID = object_id(N'[表名]') AND OBJECTPROPERTY(ID, 'IsTable') = 1) PRINT '存在' ELSE PRINT'不存在' 例如: use fireweb; go IF EXISTS (SELECT * FROM dbo.SysObjects WHERE ID = object_id(N'TEMP_TBL') AND OBJECTPROPERTY(ID, 'IsTable') = 1) PRINT '存在' ELSE PRINT'不存在' 2、临时表是否存在: 方法一: use fireweb; go if exists(select * from tempdb..sysobjects where id=object_id('tempdb..##TEMP_TBL')) PRINT '存在' ELSE PRINT'不存在' 方法二: use fireweb; go if exists (select * from tempdb.dbo.sysobjects where id = object_id(N'tempdb..#TEMP_TBL') and type='U') PRINT '存在' ELSE PRINT'不存在'
