要显示时间戳记值中的唯一日期,请在MySQL中使用FROM_UNIXTIME()方法。让我们首先创建一个表-
mysql> create table DemoTable -> ( -> timestampValue bigint -> );
使用插入命令在表中插入一些记录-
mysql> insert into DemoTable values(1538332200); mysql> insert into DemoTable values(1577730600); mysql> insert into DemoTable values(1488652200);
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-
+----------------+ | timestampValue | +----------------+ | 1538332200 | | 1577730600 | | 1488652200 | +----------------+ 3 rows in set (0.00 sec)
以下是从时间戳值显示日期的查询-
mysql> select from_unixtime(timestampValue) as Date from DemoTable;
这将产生以下输出-
+---------------------+ | Date | +---------------------+ | 2018-10-01 00:00:00 | | 2019-12-31 00:00:00 | | 2017-03-05 00:00:00 | +---------------------+ 3 rows in set (0.00 sec)
