RE: [eclipselink-users] Logging SQL results


at the "finest" log level for each retrieved object the registration in the UOF 
is logged, as the following line is showing 

[EL Finest]: UnitOfWork(20054554)--Register the existing object x.y.z.XYZ@3878ab58

- and a custom toString() implementation may offer object state details, right?

ALL is the same as FINEST, EclipseLink never logs the results, as this could
generate a lot of stuff.  I agree it is sometimes useful though, so feel
free to log a bug for this.  You can log the results yourself using a
SessionEventListener (postExecuteQuery()).
