将MySQL Unix-Timestamp格式转换为日期格式？

要实现这个功能，以下是语法

select date_format(from_unixtime(yourColumnName),'%b %d, %Y %l:%i %p PDT') from yourTableName;

要理解上面的语法，让我们创建一个表。创建一个表的查询如下：

mysql> create table unixTimeStampFormatDemo
   -> (
   -> Id int NOT NULL AUTO_INCREMENT PRIMARY KEY,
   -> MyTimeStampValue bigint
   -> );
Query OK, 0 rows affected (0.59 sec)

使用insert命令在表中插入一些记录。查询如下 –

mysql> insert into unixTimeStampFormatDemo(MyTimeStampValue) values(1334428200);
Query OK, 1 row affected (0.20 sec)
mysql> insert into unixTimeStampFormatDemo(MyTimeStampValue) values(1513881000);
Query OK, 1 row affected (0.15 sec)
mysql> insert into unixTimeStampFormatDemo(MyTimeStampValue) values(1542738600);
Query OK, 1 row affected (0.14 sec)
mysql> insert into unixTimeStampFormatDemo(MyTimeStampValue) values(1551637800);
Query OK, 1 row affected (0.15 sec)

使用select语句从表中显示所有记录。查询如下 –

mysql> select *from unixTimeStampFormatDemo;

以下是输出

+----+------------------+
| Id | MyTimeStampValue |
+----+------------------+
|  1 | 1334428200       |
|  2 | 1513881000       |
|  3 | 1542738600       |
|  4 | 1551637800       |
+----+------------------+
4 rows in set (0.00 sec)

这是将MySQL Unix-Timestamp格式转换为日期时间的查询

mysql> select date_format(from_unixtime(MyTimeStampValue),'%b %d, %Y %l:%i %p PDT') from unixTimeStampFormatDemo;

以下是输出

+-----------------------------------------------------------------------+
| date_format(from_unixtime(MyTimeStampValue),'%b %d, %Y %l:%i %p PDT') |
+-----------------------------------------------------------------------+

| Mar 04, 2019 12:00 AM PDT                                           |
+-----------------------------------------------------------------------+
4 rows in set (0.00 sec)
