這是我第一次用UPDATE(mysql)這段代碼沒有發送更新到我的mysql數據庫/表/行。我花了幾個小時在php.net上,但從我目前的水平或php知識中可以看到它的權利,並且因爲我錯了,他們我'啞'=}。 我在mysql上啓用了登錄 - 沒有用的mysql UPDATE不更新mysql錶行
這是來自ZEND服務器:所以它似乎是通過,但它不在mysql數據庫中更新。 功能名稱:請求mysql_query 函數參數: 'UPDATE廣告SET adcode = \' 7000sbjhbjhbhjb \」 WHERE ads_ID = 8'
任何指針/幫助深表感謝。

我不知道PHP,所以我可能會關閉它,但它看起來像你是d在嘗試更新數據庫之前,先從數據庫中選擇一個元組。由於要更新的元組不存在,因此無法對其進行更新。如果刪除刪除代碼會發生什麼? –
@ No'amNewman代碼只在觸發刪除操作時執行:) –
