在 SQL 的日期时间中添加时区偏移

Question

Would like to convert timestamp stored in SQL to a specific timezone.

SQL Query to offset created_at time by -33000

select cast(created_at - 33000 as date) from table_name

The query is working fine but it's giving NULL for timestamp 2019-11-14 02:52:31 .

Any hints is appreciated.

Answer 1

Try this:

SQL SERVER:

Your query will cause some explicit conversion error . So you have to convert it into proper Datetime , and then try you query.

select cast(CAST('2019-11-14 02:52:31' AS DATETIME) - 33000 as date)

MySQL

You have to use DATEADD function.

SELECT DATE_ADD('2019-11-14 02:52:31', INTERVAL -330 MINUTE);

The output will be 2019-11-13 21:22:31

Hope this will fix your issue.
