sql server 2000/2005 判断存储过程、触发器、视图是否存在并删除

1、判断是否存在addOneArticle这个存储过程  if Exists(select name from sysobjects where NAME = 'addOneArticle' and type='P')      drop procedure addOneArticle  2、判断是否存在countAr这个触发器  if exists(select * from dbo.sysobjects where id = object_id(N'[dbo].[countAr]') and OBJECTPROPERTY(id, N'IsTrigger') = 1)     drop trigger countAr  3、判断是否存在View_1这个视图  IF EXISTS (SELECT TABLE_NAME FROM INFORMATION_SCHEMA.VIEWS WHERE TABLE_NAME = N'View_1')      DROP View View_1  4、判断是否存在USER_Fun这个用户函数

(注意此处的type 有两种,分别是'TF'-Table-valued Function 表值函数 或'FN'-Scalar-valued Function 标量值函数)  if exists(select * from dbo.sysobjects where id = object_id(N'[dbo].[USER_Fun]') and (type = 'FN' or type = 'TF'))      DROP FUNCTION USER_Fun 

5、判断表'Tb'是否存在  if (exists (SELECT * FROM dbo.sysobjects where id = object_id(N'Tb')and OBJECTPROPERTY(id, N'IsUserTable') = 1))  DROP TABLE Tb

6、判断数据库是否存在

if exists( select * from master.dbo.sysdatabases where dbid=db_ID( 'scbjdb' ) )

drop database scbjdb

else

print 'no exist scbjdb'
