Sql help

Hi group, I need a little help in sql coding.

I have two files, and Header (H) and Details (D) with join fields Model and
Id.

Since the users can browse them indipendently I devoleped programs to:

- input/validate parameters
- paramter parser to sql select
- reader program to feed pages to front end presentation
- front end programs

on both the files.

Now I would like to add to the detail selections the headers selections.

The parameters parser will produce:

Detail: select * from d where item = 'XX'....

Header: select * from h where customer = 'YY'...

How can code to make detail include only the records present in header
select without writing a new parser (a change in the detail is a must but
not a copy of header paraser)?

Has to be SQLRPGLE and without temp files.

Thanks fro your help
Marco
