_SQL := 'SELECT TmessageId FROM tmpBids WHERE TphoneNumber = ' || quote_literal(phoneNumber) || ' AND Tbid = ' ||
aBid;
FOR rec IN EXECUTE _SQL LOOP bidCount := rec._qv; END LOOP;
This works ok as long as the SELECT query returns rows. Of course, if it
returns multiple rows bidCount variable will hold just the last row
value, but the design of application is like that so the query from the
start returns only one row, or returns no rows.
Of course, if it returns no rows, I'm presented with an error, saying:
ERROR: record "rec" has no field "_qv"
This is logical. My question would be is there a way around this
withouth first doing SELECT COUNT(*) FROM tmbBids WHERE ..., and then if
COUNT(*) is zero THEN bidCount := NULL ELSE if COUNT(*) is not zero then
do SELECT from the begining?
