Is Stored Procedure ok for you?
Do you need Year or you need years, months, days?

 

by: hobbit72Posted on 2003-06-12 at 12:18:25ID: 8711806

this should get you on ths right track

for a float value
select (CURRENT_DATE - cast('15-feb-1972' as date)) / 365.25 from rdb$database;

for a simple integer value
select extract( year from CURRENT_DATE) - extract(year from cast('15-feb-1972' as date)) from rdb$database;

so your sql would look something like
select (CURRENT_DATE - you_date_field) / 365.25 as the_age from your_table

hope this helps.

select cast((((''now'' - [date of birth]) - MOD((''now'' - [date of birth]),365)) / 365) as integer) AGE from [table_name]

Tried and tested :) works a bute! :) you need to import the mod command from the freeudf lib
