Question

我正在尝试使用看起来像这样的SQL查询：

'SELECT day(created), hour(created), minute(created), count(*) FROM `delivery` WHERE     `type_id`=1 AND `created`>=`2014-05-19 00:00:00` AND `created`<=`2014-05-19 23:59:59` GROUP BY     day(created),hour(created),minute(created) ORDER BY
day(created),hour(created),minute(created);

这在续集专业版中完美运行，但在快递中导致以下错误：

Error: ER_PARSE_ERROR: 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 'query' at line 1 at Query.Sequence._packetToError

任何帮助都将受到高度赞赏。

提前致谢！

Answer 1

在MySQL查询中使用datetime值时，必须使用

'2014-05-19 00:00:00' //(surrounded by '')

而不是

`2014-05-19 00:00:00` //(surrounded by ``)

因此，您的查询应如下所示：

SELECT 
  day(created), hour(created), minute(created), count(*)
FROM
  delivery
WHERE
  type_id = 1
    AND created >= '2014-05-19 00:00:00'
    AND created <= '2014-05-19 23:59:59'
GROUP BY day(created) , hour(created) , minute(created)
ORDER BY day(created) , hour(created) , minute(created);
