complex query using postgresql

["Pau Marc Munoz Torres" <paumarc@xxxxxxxxx>]

Hi everybody

  I have de following table where i can perform two different queries:

select * from precalc where idr(p1, p4, p6, p7, p9, 'HLA-DR7')>2; where idr is a function used to create indicies

and

select * from precalc where p1='S';

Now i would like to perform a query as :

select * from precalc where idr(p1, p4, p6, p7, p9, 'HLA-DR7')>2 and p1='S'...;


but i don't know how

any body can help me?

thanks
