Newbie : URGENT : SELECT ... AS

Hi all I am trying to make searches based on the age of a person. The db contains only the Date of Birth. So... My first attempt was to try the following : (this is all done in the command line on Win2000) SELECT firstname, surname, dob, floor((to_days(curdate())-to_days(DOB))/365) AS age FROM artistes; This works and returns all the values with the addition of an age column with what appears to be the correct age. However... When I try adding a WHERE clause: SELECT firstname, surname, dob, floor((to_days(curdate())-to_days(DOB))/365) AS age FROM artistes WHERE age = "25"; I get ERROR 1054: Unknown column 'age' in 'where clause' How am I to use this 'virtual' age column in my searches? I want to be able to search on exact and age ranges plus display the age in the returned results. Any ideas/feedback truly welcome, I am 'under the cosh' to get this done asap!!!
