MySQL：列計數與第1行的值計數不匹配

Question

對於冗長的代碼，我表示歉意，但我試圖創建一個審計表（稱爲aud_candles），它是「蠟燭」的副本，但是具有新的唯一鍵，aud_can_id。在「蠟燭」更新發生之前，我希望觸發器將該行的當前狀態保存在「aud_candles」中。

UPDATE candles set can_name = 'Test Name 2' WHERE can_id = 1; 

在進行更新我收到：

錯誤

列數並不在行1

匹配值計數如果我刪除觸發一切工作正常，所以它必須與觸發器相關？

Answer 1

我不知道這是否是一個錯字錯誤或沒有，但你必須使用comma而不是period對values條款某處

.... 
OLD.can_snt_id, 
OLD,can_wick_id, -- << here, it should be period. 
OLD.can_wax_id, 
...
