I had a similar question recently regarding sampling 5 records from a flat sequential file, but now I need to do it with a DB2 query :

Code:
Select name,
     address,
     zip_code
     from mydatabase_mytable
     where zip_code in ('11111','22222','33333')


but I only want 5 of each zip code specified...

Thanks for any help....

tcurrier,

If you are running DB2 Version 9 then you can use RANK OLAP function. Check this link
