I have a few SQL Server tables with a datetime field that really only has to contain dates… and the fact that it’s a datetime object violates data integrity, because it’s possible for data to be inserted with a time – which isn’t really valid for this field. The result is that we have to convert it and strip off the time every single time we use it. We’ve considered adding triggers to make sure that no data can even get in with a time attached… but it seems to me that this should really be part of the database software, and shouldn’t need to be specifically programmed each time.
Why doesn’t SQL Server have separate date and time data types? Is this going to change in the near future? Do other database platforms have this functionality?
SQL Server 2008 has DATE and TIME data types.
What version are you using?
