Problem with array in plpgsql function .. please help :-)

Hi all,

  I cannot find what is the problem with my function below.  The
following line in the function  :    AND PD.PDPONUM = ANY (receivingIds)

don't work.  If I change this line by    AND PD.PDPONUM = 1734 (Hardcode
a given value) I get a result row.

When I call the same function

 select * from usp_Commande_Dues_Retourner('{\'1734\'}', 'M',
'2005-02-02', '2005-11-02', 'EN' );

with the real line I get no result?

Any idea? What is the difference between AND PD.PDPONUM = 1734      and
AND PD.PDPONUM = ANY (receivingIds)



Thanks for your help .. I'm messing around this problem for several
hours now .. and haven't found the answer yet.

Best Regard
/David
