判斷預存程序、觸發器、視圖是否存在並刪除

1、判斷是否存在addOneArticle這個預存程序if Exists(select name from sysobjects where NAME = 'addOneArticle' and type='P')drop procedure addOneArticle2、判斷是否存在countAr這個觸發器if exists(select * from dbo.sysobjects where id = object_id(N'[dbo].[countAr]') and OBJECTPROPERTY(id, N'IsTrigger') = 1)drop trigger countAr3、判斷是否存在View_1這個視圖IF EXISTS (SELECT TABLE_NAME FROM INFORMATION_SCHEMA.VIEWS WHERE TABLE_NAME = N'View_1')DROP View View_14、判斷是否存在USER_Fun這個使用者函數(注意此處的type 有兩種,分別是'TF'-Table-valued Function 資料表值函式 或'FN'-Scalar-valued Function 純量值函式)if exists(select * from dbo.sysobjects where id = object_id(N'[dbo].[USER_Fun]') and (type = 'FN' or type = 'TF'))DROP FUNCTION USER_Fun5、判斷表'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 Tb6、判斷資料庫是否存在if exists( select * from master.dbo.sysdatabases where dbid=db_ID( 'scbjdb' ) )drop database scbjdbelseprint 'no exist scbjdb'
