CREATETABLEdatetimes(idINTPRIMARYKEYAUTO_INCREMENT,datetime_with_timezoneDATETIME); 1. 2. 3. 4. 2. 插入带时区的日期时间数据 接下来,我们可以插入带时区的日期时间数据。以下是插入数据的SQL语句: INSERTINTOdatetimes(datetime_with_timezone)VALUES('2022-01-01 12:00:00+01:00'); 1. 3. 查询带时...
datetime_val字段用于存储日期和时间。 timezone_val字段用于存储时区信息。 插入数据 INSERTINTOtimezones(datetime_val,timezone_val)VALUES('2022-01-01 12:00:00','UTC'),('2022-01-01 12:00:00','Asia/Shanghai'),('2022-01-01 12:00:00','America/New_York'); 1. 2. 3. 4. INSERT INTO语...
(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...

MySQL中的时间类型有三大类:日期(Date)、时间(Time)和年(Year)。 1.1 基本信息 下面的图表展示了MySQL几种类型的基本信息: 关于日期与时间类型,需要关注: 支持时间的类型有:TIME、DATETIME和TIMESTAMP; 支持日期的类型有:DATE、DATETIME和TIMESTAMP; 支持小数秒的类型有:TIME、DATETIME和TIMESTAMP; ...
datetime 1.8个字节储存(8 bytes storage) 2.实际格式储存(Just stores what you have stored and retrieves the same thing which you have stored.) 3.与时区无关(It has nothing to deal with the TIMEZONE and Conversion.) 实例对比 现在我来做个时区对他们的影响。
settime_zone =timezone 比如北京时间(GMT+0800)settime_zone ='+8:00'; 美国pst时间(GMT-08:00)settime_zone ='-8:00'; eg: mysql>settime_zone ='+8:00'; Query OK,0rows affected (0.17sec) mysql>selectnow();+---+ | now() | +---+ |2016...
通过上面实验,显然Timestamp比Datetime好像在时区处理上更方便一些,但是如果没有特殊需要,还是建议使用Datetime,Timestamp支持的时间范围只到2038年……已经指日可待了 System还是手动配置 (Timestamp的坑) 手动配置 MySQL的时区配置为System,数据库在进行时间戳处理叶,需要进行时区转换,此时需要使用内部函数Time_zone_syst...
