you anything here and you should likely pare down the size of your
join condition to something more minimal.you might want to also
make life easier and make the relation to a non_primary mapper for
Apples which maps

"schema" has to match as well. your groups_table has no "schema=".
so it would match to "tg_group.group_id".
also please use all lower case letters unless you require exact
