首先直接说结论,timestamp不带时区信息,timestamptz带有时区信息。 在insert数据的时候,timestamp不会携带时区信息,timestamptz会携带当前会话使用的时区信息 在查询的时候如果时区没有改变,则查询结果一样。 如果会话使用的时区和数据保存的时区1️⃣(也就是插入数据的时候使用的时区,不手动设置时区的话就是配置文...
A column named “emp_joining_date” has been successfully created with the “TIMESTAMP WITHOUT TIME ZONE” data type. Let’s learn how to insert DateTime values to a “TIMESTAMP” column in Postgres: INSERT INTO emp_data(emp_id, emp_name, emp_joining_date) VALUES(1, 'John', '2021-12...

,可以使用TIMESTAMP数据类型和DEFAULT关键字来实现。 首先,TIMESTAMP数据类型用于存储日期和时间的值。它可以精确到微秒级别,并且支持时区的设置。 要在PostgreSQL中创建默认时间戳,可以在表的列定义中使用DEFAULT关键字。例如,假设我们有一个名为"users"的表,其中包含一个名为"created_at"的列,我们可以将其定义为具有...
