This is covered in the manual. Look for ....you guessed it ... SQL
injection.
BTW You can help yourself by thinking of _all_ the ways your queries
(and data) could be hijacked or made nonsense. For example what happens
if your date of birth to age routine has a bug - do you always validate
_all_ your data or at least do sanity checks - at point of database
storage - not necessarily the raw data?
There are plenty of articles : Google is your friend.
