的SQL Server不執行DELETE語句

我創建了一個SQL查詢W/C具有Delete聲明可惜Delete聲明似乎不執行。我的SQL語句有什麼問題。的SQL Server不執行DELETE語句

這是我的代碼：

BEGIN TRAN 
BEGIN TRY 
DECLARE @Mid VARCHAR(100) = '100303000' 
DECLARE @Cnt INT 
DECLARE @ScHeader TABLE 
(
    ScHeaderId UNIQUEIDENTIFIER 
) 
declare @SCHeaderId uniqueidentifier 
    -- get ids to be deleted 
    INSERT INTO @ScHeader(ScHeaderId) 
    SELECT scd.ServiceChargesId 
    FROM ServiceChargeDetails scd 
    INNER JOIN ServiceCharges sc ON scd.ServiceChargesId = sc.ServiceChargesId 
    INNER JOIN CreditCardMID cc ON cc.CreditCardMIDId = scd.CreditCardMIDId 
    WHERE cc.MID = @Mid; 
     /* 
      do some other task here Related to @ScHeaderId 
     */ 

    SELECT @Cnt = COUNT(*) FROM CreditCardMID WHERE MID = @Mid; 
    Print 'Count before delete ' + Cast(@Cnt as VARCHAR(10)) 
    PRINT 'Deleting Mid ' + @Mid; 
    DELETE FROM CreditCardMID WHERE MID = @Mid; -- not executed 
    PRINT 'Done deleting mid '; -- -- not executed 
    SELECT @Cnt = COUNT(*) FROM CreditCardMID WHERE MID = @Mid;-- not executed 
    Print 'Count after delete ' + Cast(@Cnt as VARCHAR(10)) -- not executed 
    COMMIT TRAN 
END TRY 
BEGIN CATCH 
    ROLLBACK TRAN 
    PRINT @@ERROR 
END CATCH

下面是從消息窗口中的結果：

也許嘗試打印'ERROR_MESSAGE（）'或'ERROR_NUMBER（）'在'CATCH'找出實際的錯誤：使用TRY ...在Transact-SQL CATCH（https://technet.microsoft.com/en-us/library/ms179296%28v= sql.105％29.aspx） – har07

查找觸發器'CreditCardMID' –

觸發器花費我一段時間。謝謝A –

的「0」之後出現「（受影響0行（或多個））」意味着刪除不起作用，並觸發了口號。你能不抓運行該代碼（內部的begin tran /回滾TRAN）對，看看是什麼錯誤（我相信它從CreditCardMID表觸發錯誤）

我發現觸發器W/C限制行刪除基於一定的條件。感謝user2818323。 –
