Group Query

Hi,

It's probably because I'm struggling with array queries but how can I
get the (textual) list of groups allocated to the current user?

I can get the current_user and extract the id out of pg_user, however I
need to then match this to an element as part of a list in pg_group,
this is the part I can't find how how to do. I'd like it as a ResultSet
with each element with the textual group name

Thanks for any help,

Rob

st=con.preparedStatement(select groname from pg_group where ?=any(grolist));
st.setInt(1,uid);

maybe?

Thanks thats better than my :-
select groname from pg_group where (array_to_string(grolist, 'x') ||
'x') like '%' || (select usesysid from pg_user where
usename=current_user) || 'x%'

I wasn't aware of the any operator!

Thanks a lot!
