[Monetdb-developers] Constraint violations with all details

Hi, I cannot find it back in the trackers but I think it have asked this question before. Would it be possible to output the actual failing constraint details instead of 'just an error'. sql>alter table relation_members_way add constraint relation_to_way_fkey foreign key(to_way) references ways; !SQLException:assert:INSERT INTO: FOREIGN KEY constraint 'relation_members_way.relation_to_way_fkey' violated Inserting with INSERTS will give a nice error, because the query it self contains the problem. This is not true for a copy into, or in this respect just an alter table. Stefan ps. indeed I have to think too long about a query that will show me the non existing primary keys.
