SQL Server 如果視圖存在執行刪除

IF EXISTS(Select Name From Sysobjects Where Name='P_ExistsDropView' And Xtype='P')
DROP PROC P_ExistsDropView
GO
Create Proc P_ExistsDropView
(
@DelView Varchar(200)
)
As

Declare @SQLText Varchar(1000)
If Exists(Select Top 1 Name From Sysobjects Where Name=@DelView And XType='V') 
Begin
  Set @SQLText='Drop View ' + @DelView
  Exec(@SQLText)
End

Exec P_ExistsDropView 'View'
