将MySQL时间戳转换为UNIX时间戳？
要将MySQL时间戳转换为UNIX时间戳，请使用UNIX_TIMESTAMP()。以下是语法-
select unix_timestamp(yourColumnName) from yourTableName;
让我们首先创建一个表-
mysql> create table DemoTable( Duetimestamp timestamp );
使用插入命令在表中插入一些记录-
mysql> insert into DemoTable values(now());
mysql> insert into DemoTable values('2016-01-21 12:34:00');
mysql> insert into DemoTable values('2018-05-01 02:00:00');
mysql> insert into DemoTable values('2017-03-02 01:10:20');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-
+---------------------+ | Duetimestamp | +---------------------+ | 2019-08-20 20:48:45 | | 2016-01-21 12:34:00 | | 2018-05-01 02:00:00 | | 2017-03-02 01:10:20 | +---------------------+ 4 rows in set (0.00 sec)
以下是将MySQL时间戳转换为UNIX时间戳的查询-
mysql> select unix_timestamp(Duetimestamp) from DemoTable;
这将产生以下输出-
+------------------------------+ | unix_timestamp(Duetimestamp) | +------------------------------+ | 1566314325 | | 1453359840 | | 1525120200 | | 1488397220 | +------------------------------+ 4 rows in set (0.04 sec)
