Format time as “24-hour Military Time”?

问题

I am updating some SQL Server 2000 code to SQL Server 2008R2, and there is function that looks a lot like this for converting the time into 24 hour format. What is a cooler/more clever way to do that in T-SQL?

回答1:

If all you want is just military time:

SELECT CONVERT(VARCHAR(8), GETDATE(), 108) AS MilitaryTime

回答2:

If you want time till second, then use this:

SELECT GETDATE() 'Today', 
       CONVERT(VARCHAR(8), GETDATE(), 108) 'hh:mi:ss'

IF you want time till millisecond, then use this:

SELECT GETDATE() 'Today',
    CONVERT(VARCHAR(12),GETDATE(),114) 'hh:mi:ss:mmm'

GETDATE() is used for current date you can pass any variable here.
