SQL tip

Quick SQL tip that I find useful. If you want just the date part of a datetime value, the following neat expression yields it:

SELECT DATEADD(d, 0, DATEDIFF(d, 0, datetime_column))

This is useful for comparing dates. Alternative approaches include casting to string, and comparing the date parts (day, month, year) separately. The context determines which is most appropriate.
