QueryByCriteria#addGroupBy question

["Hiller, Frank RD-AS2" <Fr...@heidelberg.com>]

Hi,
 
I'm using ojb1.0.3 and Oracle 10g.
I tried to use QueryByCriteria#addGroupBy but I get the error
"java.sql.SQLException: ORA-00979: not a GROUP BY expression"
 
What's the way to retrieve a collection of objects, filtered with the
"group by" attribute?
 
Thanks,
Frank

Hi,
in ojb document :
---------------------------------------
Say you use the PB to query an object O that has a collection attribute col
with five
elements a,b,c,d,e. Next you delete Objects d and e from col and store O
again with
PersistenceBroker.store(O);
PB will store the remaining objects a,b,c. But it will not delete d and e !
If you then
requery object O it will again contain a,b,c,d,e !!!
--------------------
