sql server判断表是否存在
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\'
