Hi,

Do you really want a GROUP BY here? You don't have any aggregate fields (SUM(), MAX(), etc)

For 'standard' SQL you have to include all non-aggregate SELECTed fields in the GROUP BY Clause,

Maybe you just need a SELECT Distinct?

i.e.
Select DISTINCT training.idtraining, training.course, training.subject, training.held from training
