That is an odd statement. If you know that ID_CF and numar combined form a
unique key, you don't need the "FIRST 1". If those fields don't form a
unique key, then your getting one of the rows that match those values at
random. Either drop the "FIRST 1" or add an "ORDER BY" to
get deterministic results.

Good luck,
