Selecting Records by SQL Query

Hi,

I have a database of names and addresses with dates of birth

I need to select records where age is not over 12 when the
record is selected. So, given a start date and an end date,
any selected record's age would not be over 12 by the
end date

Any SQL ideas?

Thanks a lot,

Brian

Hi Brian,

I assume it does depend on the version of SQL you're using, but in MS SQL you can do :

"SELECT * from <tablename> where (year(curdate())-year(date-of-birth))<=12"

while not completely exact, this should give you a clue how to continue (because this doesn't take into account the month/day)
You would probably need to write a stored function to have a correct calculation  (and leave it out of your emergence code, so it gets executed on the server, probably much faster)

hope this helps..

regards,

Frank

Here is some code I have used with the Easy Database (MS ACCESS)

You just need to put your dates in as needed.

Hope it is of some help.
