我正在使用UPDATE查詢對我的數據庫進行更改。我對一行中的特定單元格所做的更新將插入到數據庫中。發生了什麼是該單元格輸入爲0000-00-00後出現的空白日期空間。sql更新更新在更改列後的行中的每一列
例如，當我更新的最後審查日期，這是我應該得到什麼
Before Update
Date Received Final Review Date Date Delivered Date Accepted
2015-03-03
After Update
Date Received Final Review Date Date Delivered Date Accepted
2015-03-03 2015-08-05
Instead I get this:
Date Received Final Review Date Date Delivered Date Accepted
2015-03-03 2015-08-05 0000-00-00 0000-00-00
我試圖解決此，但我還算新的mysqli/PHP的，所以我知道我可能錯過簡單的事情。任何幫助解決這個將不勝感激。

什麼是$的值_POST [datedelivered]和$ _POST [dateaccepted]？ – momouu
在數據庫中，這些列默認設置爲NULL。 – Tony
儘量不要在sql腳本中包含這兩個。 – momouu
