How to change time(7) format from 24 to 12?

Question

I have a variable as time(7) , but it gives me values like: '17:25' . I'd like for it to be in this format: '5:25 PM' . Is there a way to do this in SQL 2012 without doing something like this:

DECLARE @aux NVARCHAR(8)='16:45:00'
SELECT CONVERT(VARCHAR(15),CAST(@aux AS TIME),100)

Answer 1

No, you cannot do anything about the format SQL Server uses to store the Time datatype. You can only use tricks like the one you mentioned at query-time to deliver the output in a desired format. Or better yet, do the formatting in the front-end application.

Answer 2

您可以尝试将DATEPART（HH ...）与case语句或IF / ELSE一起使用，以更改中午之后的时间，最后使用CONCAT上午或下午
