我有一個觸發器，我想從存儲過程中將其啓動。我使用MS訪問，當我從MS訪問運行觸發它給我一個錯誤消息（ODBC）。我想我不能使用ms訪問創建觸發器。這是我的觸發器：使用存儲過程創建觸發器
IF EXISTS
(SELECT name
FROM sys.objects
WHERE name = 'UpdateComments' AND type = 'TR')
DROP TRIGGER tblEmailHdr_abenit01.UpdateComments;
GO
CREATE TRIGGER UpdateComments
ON tblEmailHdr_abenit01
AFTER Update
AS
IF (UPDATE (Comments)) BEGIN Update ttblEmailHdr_abenit01
Set UpdateComm = GetDate()
END;
GO
這是我怎麼一直在試圖創建存儲過程的觸發器，但我得到以下錯誤味精的，當我嘗試創建存儲過程：
存儲過程：
CREATE PROCEDURE dbo.SP_AS_tblEmailHdr_Trig (@UserID as varchar(10))
AS
BEGIN
-- SET NOCOUNT ON added to prevent extra result sets from
-- interfering with SELECT statements.
--SET NOCOUNT ON;
-- Insert statements for procedure here
Declare @UserTable Varchar(50)
Declare @UserTable2 Varchar(50)
Set @UserTable = 'tblEmailHdr_' + @UserID ;
Set @UserTable2 = 'tblEmailHdr_' + @UserID + '.UpdateComments' ;
IF EXISTS
(SELECT name
FROM sys.objects
WHERE name = 'UpdateComments' AND type = 'TR') DROP TRIGGER @UserTable2
GO
CREATE TRIGGER UpdateComments
ON @UserTable
AFTER UPDATE
AS
IF (UPDATE (Comments))
BEGIN
--RAISERROR (50009, 16, 10)
Update @UserTable
Set UpdatedComm = GetDate()
END
GO
END
GO
錯誤味精，我得到：
Msg 102, Level 15, State 1, Procedure SP_AS_tblEmailHdr_Trig, Line 23
Incorrect syntax near '@UserTable2'.
Msg 102, Level 15, State 1, Procedure UpdateComments, Line 2
Incorrect syntax near '@UserTable'.
Msg 1087, Level 15, State 2, Procedure UpdateComments, Line 8
Must declare the table variable "@UserTable".
Msg 102, Level 15, State 1, Line 2
Incorrect syntax near 'END'.

@Vikram內取出GO' GO'可能會阻止程序被創建，但它仍然不會導致觸發器被執行，因爲OP似乎需要。 – Yuck 2012-02-21 01:35:28
@Yuck：你說得對。觸發器會自動執行..但我認爲他正在嘗試創建一個。 – Vikram 2012-02-21 01:39:29
