How to round up a date in SQL server?

edit

To round up a date in SQL Server, you can use the DATEADD and DATEDIFF functions to add a certain number of days to the original date based on the rounding interval and then use the FLOOR function to truncate any remaining time after the new date has been calculated. Here's an example to round up a date to the nearest month:

SELECT DATEADD(MONTH, DATEDIFF(MONTH, 0, GETDATE()) + 1, 0) -- add one month and set day to 1 OR SELECT CONVERT(date, DATEADD(s, -1, DATEADD(mm, DATEDIFF(m, 0, GETDATE()) + 1, 0))) -- set last day of month

This will return the first date of the next month. If you want to round up to a different interval such as year, week, etc., simply replace the MONTH parameter in the DATEADD and DATEDIFF functions with the desired interval.
