我应该为 MySQL SQL 数据库中的“2020-04-11T19:54:00.0000000Z”使用什么数据类型？

Question

What time format is 2020-04-11T19:54:00.0000000Z ? Should it be entered in a SQL database as DATE , DATETIME , TIMESTAMP , TIME , or YEAR ?

Answer 1

This is ISO-8601 . The format includes date, time with possible precision of fractions of second, and time zone information.

Basically you should use either DATETIME, or convert to UNSIGNED INT, depending on what you prefer.

The devil is in details. If all the values you receive end with Z, then you can assume you receive datetime in UTC. Just use DATETIME and take care your MySQL server is set up to UTC timezone.

Do you need to store timezone name for later retrieval? In this case, you will need to parse input value into two fields. One field to keep datetime in UTC format and second to store time zone value (MySQL's datetime field type does not store time zone value). Also take care of converting input values to UTC. If you're using MySQL version 8.0.19 or later, it can do that for you .

Do take care to set your MySQL server time zone variable to UTC.
