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\'
