时间戳转化

1、将日期格式转换成时间戳查询

SELECT
yx_user. NAME AS 用户名,
yx_space_podcast.content AS 发布内容,
FROM_UNIXTIME(
yx_space_podcast.created_at
) AS 发布时间,
yx_location. NAME AS 城市,
yx_space_podcast.user_id AS 用户ID
FROM
yx_space_podcast
LEFT JOIN yx_user ON yx_user.id = yx_space_podcast.user_id
LEFT JOIN yx_location ON yx_user.location_id = yx_location.id
WHERE
yx_space_podcast.created_at > UNIX_TIMESTAMP('2019-04-01 00:00:00')
AND yx_space_podcast.created_at < UNIX_TIMESTAMP('2019-04-27 00:00:00')
AND yx_space_podcast.is_delete = 0;

上面查询用到了两个函数

FROM_UNIXTIME： 将时间戳转换成日期格式 默认是2019-04-28 00:00:00

UNIX_TIMESTAMP: 将日期转换成时间戳格式
