Question

我正在尝试在特定日期签入和结帐之间获取结果。我得到以下错误：

Error Number: 1064

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '14:00:00 AND b.end <= 2016-03-31 11:00:00' at line 4

SELECT * FROM properties as a LEFT JOIN reservations as b ON b.room_id = a.room_id WHERE a.client = 7 AND b.start >= 2016-03-01 14:00:00 AND b.end <= 2016-03-31 11:00:00

Filename: controllers/Transactions.php

Line Number: 741

SQL：

$sql = "SELECT *
        FROM properties as a
        LEFT JOIN reservations as b ON b.room_id = a.room_id
        WHERE a.client = $client AND b.start >= $start AND b.end <= $end";
        $query = $this->db->query($sql);

日期时间是$ start和$ end ..我做错了什么？感谢

您需要为start和end日期列添加引号，不能使用不带引号的日期列：

b.start >= 2016-03-01 14:00:00 AND b.end <= 2016-03-31 11:00:00

这应该是：

b.start >= '2016-03-01 14:00:00' AND b.end <= '2016-03-31 11:00:00'

修改后的查询：

SELECT *
FROM properties AS a
LEFT JOIN reservations AS b ON b.room_id = a.room_id
WHERE a.client = '$CLIENT' AND b.start >= '$START' AND b.end <= '$END'

在签入和签出（DATETIME）错误之间获得结果
