Sql 判斷存儲過程是否存在的方法

--判斷數據庫是否存在
if exists(select * from master..sysdatabases wherename=N'庫名')
print 'exists'
else
print 'not exists'
---------------
-- 判斷要創建的表名是否存在
if exists (select * from dbo.sysobjects where id =object_id(N'[dbo].[表名]') and OBJECTPROPERTY(id, N'IsUserTable') =1)
-- 刪除表
drop table [dbo].[表名]
go
---------------
--判斷要創建臨時表是否存在
If Object_Id('Tempdb.dbo.#Test') Is Not Null
begin
print '存在'
end
else
begin
print '不存在'
end
---------------
-- 判斷要創建的存儲過程名是否存在
if exists (select * from dbo.sysobjects where id =object_id(N'[dbo].[存儲過程名]') and OBJECTPROPERTY(id, N'IsProcedure')= 1)
-- 刪除存儲過程
drop procedure [dbo].[存儲過程名]
go
---------------
-- 判斷要創建的視圖名是否存在
if exists (select * from dbo.sysobjects where id =object_id(N'[dbo].[視圖名]') and OBJECTPROPERTY(id, N'IsView') =1)
-- 刪除視圖
drop view [dbo].[視圖名]
go
---------------
-- 判斷要創建的函數名是否存在
if exists (select * from dbo.sysobjects where id =object_id(N'[dbo].[函數名]') and xtype in (N'FN', N'IF', N'TF'))
-- 刪除函數
drop function [dbo].[函數名]
go
if col_length('表名', '列名') is null
print '不存在'
select 1 from sysobjects where id in (select id from syscolumnswhere name='列名') and name='表名'
