>I need to make a reports, where I can see al clients with their birthday, having the date of birth, an initial date and a final date.
Do you mean where birthday is between initial date and final date?
Then it would be something like:
SELECT * from CLIENTS WHERE BETWEEN(birth_date, ldInitial_date, ldFinal_date)
