PDO和MySQL之间
问题描述：
我正在尝试让PDO与介于两者之间"的MySQL一起使用.下面是我的代码:
I'm trying to get PDO to work with a MySQL 'between'. Below is my code:
$DBH = new PDO("mysql:host=$host;dbname=$dbname", $user, $pass);
$start_date = date('Y-m-d H:i:s', mktime(0, 0, 0, 11, 1, 2009));
$end_date = date('Y-m-d H:i:s', mktime(23, 59, 59, 11, 30, 2009));
$STH = $DBH->prepare("SELECT * FROM `table` WHERE `start_date` BETWEEN ':start_date' AND ':end_date'");
$STH->bindParam(':start_date', $start_date, PDO::PARAM_STR);
$STH->bindParam(':end_date', $end_date, PDO::PARAM_STR);
$STH->execute();
var_dump($row);
返回的是一个值为'0'或'NULL'的数组.当我对结束日期进行硬编码时，它就像将start_date设置为-1一样，重新调整了end_date之前的所有行.那么，我在这里做错了什么?
What gets returned is an array with '0' or 'NULL' for values. When I hard code the end date, it acts as if start_date is set to -1, retuning me all rows before the end_date. So, what am I doing wrong here?
答
不要用单引号引起来的值.
Don't wrap the values with single quote.
$STH = $DBH->prepare("SELECT * FROM `table` WHERE `start_date` BETWEEN :start_date AND :end_date");
