Question

我需要在06:00 AM到08:00 AM之间从MySQL数据库表中获取所有行。

由于我不理解输出，因此我启动了此sql查询，但未成功。

时间间隔（06:00 AM和08:00 AM）不正确，如何解决呢？

在此先感谢您的帮助。

mysql> SELECT
    DAYOFWEEK(dStart) AS DOW,
    dStart,
    dEnd,
    cd
FROM
    `2019tblCd`
WHERE
    (
        cd IN ('P')
        AND DAYOFWEEK(dStart) BETWEEN 2
        AND 6
        AND (
            time(dStart) >= '06:00:00'
            OR time(dEnd) <= '08:00:00'
        )
    )
ORDER BY
    STR_TO_DATE(dStart, '%Y-%m-%d %H:%i:%s') DESC
LIMIT 10;

正确的输出是：

+-----+---------------------+---------------------+----+
| DOW | dStart              | dEnd                | cd |
+-----+---------------------+---------------------+----+

试试这个：

mysql> SELECT
    DAYOFWEEK(dStart) AS DOW,
    DATE_FORMAT(dStart,'%Y-%m-%d %h:%i:%s') as dStart,
    DATE_FORMAT(dEnd,'%Y-%m-%d %h:%i:%s') as dEnd,
    cd
FROM
    `2019tblCd`
WHERE
    (
        cd IN ('P')
        AND DAYOFWEEK(dStart) BETWEEN 2
        AND 6
        AND (
            DATE_FORMAT(time(dStart),'%H:%i:%s') >= '18:00:00'
            AND DATE_FORMAT(time(dEnd),'%H:%i:%s')  <= '20:00:00'
        )
    )
ORDER BY
    STR_TO_DATE(dStart, '%Y-%m-%d %H:%i:%s') DESC
LIMIT 10;
