Hi!
I've been unable to get nested queries to work. e.g:
select x,y from z where y in (select r from t);
fails in a JDBC call (JBoss JDBC Driver). I wound up having to do =>
select r from t;
iterate through the result set and build a string list of str = 'a,b,c...',
then do a select like:
"select x,y from z where y in (" + str + ")"
Anyone have any ideas?
