mysql觸發器報錯

Explicit or implicit commit is not allowed in stored function or trigger--在存儲函數/過程  中不能顯示或隱式提交

if 條件 then  語句 end if -----語句有問題

---

check the manual that corresponds to your MySQL server version for the right syntax to use near ''

語法錯誤  在mysql中end  if 分開,if條件判斷不要()

---

 Can't update table 'sc' in stored function/trigger because it is already used by statement which invoked this stored function/trigger

陷入於死循環
