Thanks for the information, but Bruce (which I have already read) and
all other docs I´ve seen "only" mention normal subselects. I know
subselects (what a poor database engineer I would be otherwise ;-)) but
I have never seen a statement like
SELECT a, (SELECT b)
FROM xyz;
IMHO this is no normal subselect and it does not correlate with the
SQL-standard. Is it a trick?
