Informix - Problem description

Problem IT14450 Status: Closed

LEFT-OVER ERROR FROM JOIN PHASE CAN MAKE SORT OR FETCH FAIL INADVERTENTLY

product:
INFORMIX SERVER / 5725A3900 / C10 - IDS 12.10
Problem description:
A query joining two columns where one column's content might be
not fully convertible to the other column's type, might fail
either during sort (if e.g. ORDER BY was used), or subsequent
fetch would return an error - even though the join succeeded and
had silently ignored the error.

For example you'd join an INTEGER to a DECIMAL(13,0) with the
later containing values larger than what an integer can hold.
Such join should be valid and simply not return anything for
those large decimal values.
