Hello everyone.

Hello everybody,
I have the table (named for example mytable) and trigger on insert. The
trigger do the following (in real trigger the logic is more complicated, but

The following sql is intended to produce a list of all unique SOURCEs,

hmm, but if I try to constrain the inner query to the source_id of the outer

select sl.source_id, max(score) from source s
inner join sourcelevel sl on s.source_id = sl.source_id
inner join level l on sl.level_id = l.level_id
group by 1
This is the highest score per source_id.

There is probably a more elegant way, but this could help you.
select i.source_id, nm.name, i.mxscore from (
select sl.source_id, max(score) mxscore from source s
inner join sourcelevel sl on s.source_id = sl.source_id
inner join level l on sl.level_id = l.level_id
group by 1
) i
inner join (
thanks! I think this is the best answer I will get.
