使用MySQL查找两个datetime值之间的差异？
要查找两个日期时间值之间的差异，可以使用TIMESTAMPDIFF()。让我们首先创建一个表-
mysql> create table DemoTable -> ( -> DueDatetime1 datetime, -> DueDatetime2 datetime -> );
使用插入命令在表中插入一些记录-
mysql> insert into DemoTable values('2019-10-26 19:49:00','2019-10-26 17:49:00');
mysql> insert into DemoTable values('2019-10-26 08:00:00','2019-10-26 13:00:00');
mysql> insert into DemoTable values('2019-10-26 06:50:00','2019-10-26 12:50:00');使用select语句显示表中的所有记录-
mysql> select *from DemoTable;
这将产生以下输出-
+---------------------+---------------------+ | DueDatetime1 | DueDatetime2 | +---------------------+---------------------+ | 2019-10-26 19:49:00 | 2019-10-26 17:49:00 | | 2019-10-26 08:00:00 | 2019-10-26 13:00:00 | | 2019-10-26 06:50:00 | 2019-10-26 12:50:00 | +---------------------+---------------------+ 3 rows in set (0.00 sec)
这是要实现timestampdiff()并找到两个日期之间的差异的查询-
mysql> select abs(timestampdiff(minute,DueDatetime1,DueDatetime2)) from DemoTable;
这将产生以下输出-
+------------------------------------------------------+ | abs(timestampdiff(minute,DueDatetime1,DueDatetime2)) | +------------------------------------------------------+ | 120 | | 300 | | 360 | +------------------------------------------------------+ 3 rows in set (0.00 sec)
