我正在尝试完成连接到两个数据库的脚本，每个数据库位于不同的服务器上，并执行更新。基本上，从中选择和插入的表是相同的：我前几天进行了转储/导入。该脚本需要保持我的本地表最新的一次，因为将有每日记录插入远程的，我需要在本地保持最新。
这里的关键是我通过查看表共享的自动递增的主键SESSIONID来确定远程服务器上的新行。我试图让我的循环下面说，如果id存在于远程服务器而不是本地，则将这些记录插入本地服务器。
我通过键入php'filename'在powershell中运行以下脚本，然后我获得了两条成功的连接消息，然后收到此消息：Incorrect datetime value: '' for column 'ALERTINGTIMESTAMP' at row 1。在这个记录中，它试图插入，表格允许的日期时间值为NULL，但是我担心这是转义字符或其他东西的问题。
如何修改此设置以正确转义，或插入这些记录。
注意：在这种情况下，复制和大型转储/导入/表重新创建不适合我们。我们有几个类似的脚本运行，我们希望在这里保持相同的过程。我只是想解决这些错误，或者让某人给我一种更有效的编码脚本的方法，也许是使用max id或类似的东西。
这是脚本：
ini_set('memory_limit', '256M');
// Create connection
$conn = new mysqli($servername, $username, $password);
$conn2 = new mysqli($servername2, $username2, $password2);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
echo "Connected successfully";
// Check connection2
if ($conn2->connect_error) {
die("Connection failed: " . $conn2->connect_error);
}
echo "Connected successfully";
$latest_result = $conn2->query("SELECT MAX(`SESSIONID`) FROM `ambition`.`session`");
$latest_row = $latest_result->fetch_row();
$latest_session_id = $latest_row[0];
//Select All rows from the source phone database
$source_data = mysqli_query($conn, "SELECT * FROM `cdrdb`.`session` WHERE `SESSIONID` > $latest_session_id");
// Loop on the results
while($source_item = $source_data->fetch_assoc()) {
// Check if row exists in destination phone database
$row_exists = $conn2->query("SELECT SESSIONID FROM ambition.session WHERE SESSIONID = '".$source_item['SESSIONID']."' ") or die(mysqli_error($conn2));
//if query returns false, rows don't exist with that new ID.
if ($row_exists->num_rows == 0){

您必须使用prepare（）函数来使用参数化查询。在这里，我举了几个参数的例子，你可以自己添加其他变量。
$stmt = $conn2->prepare("INSERT INTO ambition.session (SESSIONID,SESSIONTYPE,CALLINGPARTYNO,FINALLYCALLEDPARTYNO) VALUES (:SESSIONID ,:SESSIONTYPE ,:CALLINGPARTYNO ,:FINALLYCALLEDPARTYNO)");
$stmt->bindParam(':SESSIONID', $source['SESSIONID']);
$stmt->bindParam(':SESSIONTYPE', $source['SESSIONTYPE']);
$stmt->bindParam(':CALLINGPARTYNO', $source['CALLINGPARTYNO']);
$stmt->bindParam(':FINALLYCALLEDPARTYNO', $source['FINALLYCALLEDPARTYNO']);
$stmt->execute();
