我从 Datepicker Jquery UI 获取 DATE 变量，并将其作为变量包含在 MYSQL 语句中。但 select 不适用于该变量。什么原因？

代码下方

$fromDate = new DateTime($from);
$toDate = new DateTime($to);

$fromDate2 = mysqli_real_escape_string($fromDate);
$toDate2 = mysqli_real_escape_string($toDate);

$sql = mysqli_query($mySqlConnect,"SELECT * FROM 1398_log WHERE date BETWEEN $fromDate2 AND $toDate2 ORDER by id DESC");

这里选择确定:

$sql = mysqli_query($mySqlConnect,"SELECT * FROM 1398_log WHERE date BETWEEN '2016-03-01 00:00:00' AND  '2016-06-30 23:59:59'ORDER by id DESC");

Answer 1

您需要在 sql 中以字符串形式提供日期:

$sql = mysqli_query($mySqlConnect,"SELECT * 
FROM 1398_log 
WHERE date BETWEEN '$fromDate2' AND '$toDate2'
ORDER by id DESC");
