判斷sqlserver對象是否存在（轉）

--查看對象是否已經存在  
--數據庫是否存在  
 
--if exists (select * from sys.databases where name = ’數據庫名’)    
--  drop database [數據庫名]  
    
if exists(select * from sys.databases where name='FGM_POS')  
print '存在'  
--drop database [數據庫名]  
 
--表是否存在  
 
--if exists (select * from sysobjects where id = object_id(N’[表名]’) and OBJECTPROPERTY(id, N’IsUserTable’) = 1)    
--  drop table [表名]  
    
if exists (select * from sysobjects where id =OBJECT_ID(N'[FGM_bt_ePlnMain]') and OBJECTPROPERTY(id,N'IsUserTable')=1)  
print '存在'  
--drop table [表名]  
--或  
if exists (select * from sysobjects where id =OBJECT_ID(N'dbo.FGM_bt_ePlnMain') and OBJECTPROPERTY(id,N'IsUserTable')=1)  
print '存在'  
 
--存儲過程是否存在  
 
--if exists (select * from sysobjects where id = object_id(N’[存儲過程名]’) and OBJECTPROPERTY(id, N’IsProcedure’) = 1)    
--  drop procedure [存儲過程名]   
    
if exists (select * from sysobjects where id =OBJECT_ID(N'[FGM_sp_SyncePlnMain]') and OBJECTPROPERTY(id,N'IsProcedure')=1)

--或  
if exists (select * from sysobjects where id =OBJECT_ID(N'dbo.FGM_sp_SyncePlnMain') and OBJECTPROPERTY(id,N'IsProcedure')=1)  
print '存在'  
 
--臨時表是否存在  
 
--if object_id(’tempdb..#臨時表名’) is not null      
--  drop table #臨時表名   
    
select * into #temp from dbo.FGM_bt_ConsumInfoDetail_B

print '存在'  
--或者  
if exists(select * from tempdb.dbo.sysobjects where id=OBJECT_ID(N'tempdb..#temp')and type='U')  
print '存在'  
 
--視圖是否存在  
----SQL Server 2000

--函數是否存在

print '存在'  
--drop function dbo.GetResourceName  
 
--列是否存在  
 
--if exists(select * from syscolumns where id=object_id(’表名’) and name=’列名’)    
--  alter table 表名 drop column 列名   
 
if exists(select * from syscolumns where id =OBJECT_ID('FGM_bt_ePlnMain') and name='ePlnName')  
print '存在'  
--alter table 表名 drop column 列名  
 
--判斷列是否自自增列  
 
--if columnproperty(object_id('table'),'col’,’IsIdentity’)=1    
--  print '自增列'    
--else    
--  print '不是自增列'

--查看數據庫中對象  
--select * from sys.sysobjects where name='對象名' 
 
select * from sys.sysobjects where name='FGM_bt_ePlnMain' 
 
--獲取用戶創建的對象信息
