Use OQL GroupBY for datagrid

Hi all, I’ve been working on OQL and stuck on showing groupby data on DataGrid.  DataGrid table is impersistent, and it is for displaying table.  I made this OQL below to show the sum value group by “Team” and “Supplier”. 'SELECT SUM(ttable/Price) AS price FROM MyFirstModule.transaction ttable LEFT JOIN MyFirstModule.transaction_Team/MyFirstModule.Team team LEFT JOIN MyFirstModule.transaction_Supplier/MyFirstModule.Supplier supplier GROUP BY team/team_code, supplier/supplier_code' I have set the return entity as the impersistent entity to display the table, but It did not goes well. The error message might help is “InternalOqlTextGetRequest (depth = -1):” Anybody has any information on how I can solve the problem? How would I able to see the results of OQL?   Thank you very much in advance, Regards, Yuki

So your OQL is giving the correct results, it looks fine. Your problem is just with displaying the data. No direct answer but maybe helpful: You can get some more info on the error by Project->Deploy for eclipse, then open your project in Eclipse and look for the OQL module and debug that part.
