MySQL 如何从时间戳中获取日期名称

要从时间戳中获取日期名称，请使用dayname()函数−

select dayname(yourColumnName) from yourTableName;
   让我们首先创建一个表：
  mysql> create table DemoTable
  (
  LoginDate timestamp
  );
Query OK, 0 rows affected (0.52 sec)

使用插入命令在表中插入一些记录−

mysql> insert into DemoTable values('2019-06-01');
Query OK, 1 row affected (0.12 sec)
mysql> insert into DemoTable values('2019-06-02');
Query OK, 1 row affected (0.09 sec)
mysql> insert into DemoTable values('2019-06-03');
Query OK, 1 row affected (0.09 sec)
mysql> insert into DemoTable values('2019-06-04');
Query OK, 1 row affected (0.11 sec)
mysql> insert into DemoTable values('2018-06-21');
Query OK, 1 row affected (0.09 sec)

使用select语句显示表中的所有记录−

mysql> select *from DemoTable;
