我正在使用UPDATE查询对我的数据库进行更改。我对一行中的特定单元格所做的更新将插入到数据库中。发生了什么是该单元格输入为0000-00-00后出现的空白日期空间。sql更新更新在更改列后的行中的每一列
例如，当我更新的最后审查日期，这是我应该得到什么
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
我试图解决此，但我还算新的mysqli/PHP的，所以我知道我可能错过简单的事情。任何帮助解决这个将不胜感激。
<?php
$servername = "localhost";
$username = "xxx";

// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
if (isset($_POST['update'])){
$UpdateQuery = "UPDATE Projects SET Project='$_POST[project]', Client='$_POST[client]', LastName='$_POST[lastname]', DateReceived='$_POST[datereceived]', FinalReviewDate='$_POST[finalreviewdate]', DateDelivered='$_POST[datedelivered]', DateAccepted='$_POST[dateaccepted]' WHERE Project='$_POST[hidden]'";
mysqli_query($conn, $UpdateQuery);
};
$sql = "SELECT * FROM Projects";
$result = $conn->query($sql);
echo "<table>

什么是$的值_POST [datedelivered]和$ _POST [dateaccepted]？ – momouu
在数据库中，这些列默认设置为NULL。 – Tony
尽量不要在sql脚本中包含这两个。 – momouu
