判断sqlserver对象是否存在

--查看对象是否已经存在 

--数据库是否存在 

  

--if exists (select * from sys.databases where name = ’数据库名’)   

--  drop database [数据库名] 

     

if exists(select * from sys.databases where name='FGM_POS') 

print '存在' 

--drop database [数据库名] 

  

--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' 

  

--存储过程是否存在 

  

--if exists (select * from sysobjects where id = object_id(N’[存储过程名]’) and OBJECTPROPERTY(id, N’IsProcedure’) = 1)   

--  drop procedure [存储过程名]  

     

if exists (select * from sysobjects where id =OBJECT_ID(N'[FGM_sp_SyncePlnMain]') and OBJECTPROPERTY(id,N'IsProcedure')=1) 

print '存在' 

--或 

if exists (select * from sysobjects where id =OBJECT_ID(N'dbo.FGM_sp_SyncePlnMain') and OBJECTPROPERTY(id,N'IsProcedure')=1) 

print '存在' 

  

--临时表是否存在 

  

--if object_id(’tempdb..#临时表名’) is not null     

--  drop table #临时表名  

     

select * into #temp from dbo.FGM_bt_ConsumInfoDetail_B 

if OBJECT_ID ('tempdb..#temp')is not null 

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' 

  

--视图是否存在 

----SQL Server 2000    

--IF EXISTS (SELECT * FROM sysviews WHERE object_id = '[dbo].[视图名]'   

----SQL Server 2005    

--IF EXISTS (SELECT * FROM sys.views WHERE object_id = '[dbo].[视图名]'  --SQL Server 2000 

--IF EXISTS (SELECT * FROM sysviews WHERE object_id = '[dbo].[视图名]’ 

----SQL Server 2005 

--IF EXISTS (SELECT * FROM sys.views WHERE object_id = ’[dbo].[视图名]’ 

----SQL Server 2008 

if exists (select * from sysobjects where id=OBJECT_ID(N'[dc_adplan]') and type='V') 

print '存在' 

--或 

if exists (select * from sysobjects where id=OBJECT_ID(N'dbo.dc_adplan') and type='V') 

print '存在' 

--drop view dbo.dc_adplan 

  

--函数是否存在 

  

 --if exists (select * from dbo.sysobjects where id = object_id(N’[dbo].[函数名]’) and xtype in (N’FN’, N’IF’, N’TF’))     

 -- drop function [dbo].[函数名]  

     

if exists (select * from dbo.sysobjects where id=OBJECT_ID (N'dbo.GetResourceName')and xtype in (N'FN',N'IF',N'TF')) 

print '存在' 

--或 

if exists (select * from dbo.sysobjects where id=OBJECT_ID (N'[GetResourceName]')and xtype in (N'FN',N'IF',N'TF')) 

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 

  

--判断列是否自自增列 

  

--if columnproperty(object_id('table'),'col’,’IsIdentity’)=1   

--  print '自增列'   

--else   

--  print '不是自增列'   

  

if COLUMNPROPERTY(object_id ('FGM_bt_ePlnMain'),'ePlnID','IsIdentity')=1 

print '自增列' 

else 

print '非' 

  

  

--查看数据库中对象 

--select * from sys.sysobjects where name='对象名'

  

select * from sys.sysobjects where name='FGM_bt_ePlnMain'

  

--获取用户创建的对象信息 

  

SELECT [name],[id],crdate FROM sysobjects where xtype='U'

/*   

xtype 的表示参数类型，通常包括如下这些   

C = CHECK 约束   

D = 默认值或 DEFAULT 约束   

F = FOREIGN KEY 约束   

L = 日志   

FN = 标量函数   

IF = 内嵌表函数   

P = 存储过程   

PK = PRIMARY KEY 约束（类型是 K）   

RF = 复制筛选存储过程   

S = 系统表   

TF = 表函数   

TR = 触发器   

U = 用户表   

UQ = UNIQUE 约束（类型是 K）   

V = 视图   

X = 扩展存储过程
