I tried to do this:SELECT r , a , (SELECT u , re FROM dir WHERE u = a) , cdate FROM rep
WHERE m IN(190);
... and I got:
ERROR: Subselect must have only one field
An explain shows that two subselects result in two queries, even thought
they are accessing the same row. Why can subselects only have one
field?
