因此,引入了TIME WITH TIME ZONE类型以解决这个问题。 TIME WITH TIME ZONE数据类型示例 下面是一个示例,展示如何在MySQL中创建一个表,并使用TIME WITH TIME ZONE类型存储时间值: CREATETABLEevents(event_idINTPRIMARYKEY,event_timeTIMEWITHTIMEZONE);INSERTINTOevents(event_id,event_time)VALUES(1,'12:00:00 +...
CREATETABLEtime_with_zone(idINTPRIMARYKEYAUTO_INCREMENT,time_with_zoneTIMESTAMPWITHTIMEZONE); 1. 2. 3. 4. 这段代码创建了一个名为time_with_zone的表,其中包含两个列:id和time_with_zone。id列用于唯一标识每条记录,而time_with_zone列用于存储带有时区信息的时间数据。 步骤2:插入带有时区信息的时间数...

(This does not occur for other types such as DATETIME.) By default, the current time zone for each connection is the server’s time. (默认情况下,每个连接的当前时区是服务器时间。 The time zone can be set on a per-connection basis. As long as the time zone setting remains constant, you...
只要时区设置保持不变，检索到的值与存储的值相同。若存储 TIMESTAMP 值后更改时区并检索该值，检索到的值与存储的值不同，因为两个方向的转换没有使用相同的时区。当前时区可通过 time_zone 系统变量的值获得。详细信息可查阅 MySQL 服务器时区支持的文档。实际应用示例：时间戳工作原理为清晰展示时间戳...

system_time_zone:Mysqld在启动的时候,会读取系统配置,做为固化值,此参数只读,想要更改只能重启 time_zone:可以理解为sesssion的时区配置,上面显示SYSTEM的意思是,使用CST的时区进行时间处理,此参数是动态参数,可以通过应用侧连接时直接配置,对当前session生效,也可以set global全局生效 ...
TIMESTAMP WITH TIME ZONE存储客户端的时区信息,所以也不受DBTIMEZONE影响 TIMESTAMP WITH LOCAL TIME ZONE类型数据不会存储客户端的时区信息,它根据数据库时区对客户端发来的时间进行转换,基于统一的数据库时区存储时间信息,如果用户没有指定时区信息同TIMESTAMP WITH TIME ZONE一样默认采用会话时区。把客户端输入的时...
