May be in this case i HAVE to use ReportQuery ? I'm not a query expert, but I think you are right. If you want to mix columns of different tables (/objects) you can't use the object based criteria api. You can find an example here http://db.apache.org/ojb/docu/guides/query.html#Report+Queries regards, Armin Thank in advanced , Regards -- View this message in context: http://www.nabble.com/inner-join-n%3A1-how-to-t1509312.html#a4133579 Sent from the Apache DB - ObjectRelationalBridge Users forum at Nabble.com. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
