DELETE FROM與LIMIT不工作 - 錯誤1064

Question

基本上我有這個疑問

SELECT * 
FROM `transactions` a 
WHERE Round((tender1 - `change`), 2) != (SELECT Round(Sum(total), 2) 
              FROM `transactions` b 
              WHERE b.trans_no = a.trans_no) 
     AND tender1 != 0 
LIMIT 1 

這是罰款，並返回一個單一的線，但如果我改變了語句刪除

DELETE FROM `transactions` a 
WHERE Round((tender1 - `change`), 2) != (SELECT Round(Sum(total), 2) 
              FROM `transactions` b 
              WHERE b.trans_no = a.trans_no) 
     AND tender1 != 0 
LIMIT 1 

這將返回錯誤1064無效語法

任何想法???

我不知道爲什麼你的LIMIT有，但我認爲，如果你想刪除的任意行這樣的工作：

DELETE FROM `transactions` WHERE id IN (
    SELECT id FROM `transactions` a 
    WHERE ROUND((TENDER1 - `CHANGE`),2) != (SELECT ROUND(SUM(TOTAL),2) 
              FROM `transactions` b 
              WHERE b.trans_no = a.TRANS_NO) 
    AND TENDER1 != 0 
    LIMIT 1 
)
