如何指定子句在Mysql中每5分钟一次

Question

在Mysql请求中，我想指定每5分钟选择一次值

 $sql = 'SELECT * FROM table WHERE datetime BETWEEN "2016-01-04 00:00:00" 
 $sql .= 'AND "2016-01-04 12:00:00" + "(and INTERVAL 5 minutes)"';

有人有想法吗？

Answer 1

你可以试试这个：

SELECT * FROM table
WHERE datetime BETWEEN '2016-01-04 00:00:00' AND '2016-01-04 12:00:00'
GROUP BY 
UNIX_TIMESTAMP(datetime) DIV 300
