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)
