SQL query

Hello,

I would like to retrieve all the records from table A which have given
lang_id and its modification date is later then modification date of
the same id record with lang_id='pl'.

Example:

table A - data example
======================
id      | modification_date   | lang_id
--------+---------------------+------
abc     | 2002-10-11 10:12:11 | en
abc     | 2002-11-12 11:12:11 | pl
abc     | 2002-11-11 18:12:00 | de
sample  | 2003-04-15 22:43:14 | pl
sample  | 2003-05-16 11:10:15 | en
sample  | 2003-11-11 18:11:10 | de

If given lang_id would be 'en' the following record should be choosed:

sample  | 2003-05-16 11:10:15 | en

(it has mofication date later then record with id = sample and lang_id
= pl)

If you have any idea how to make SQL query for this, please help me.

Thanx,
Paul Czubilinski
