Expanding on/clarifying the comparison caveat, it's not an SQL issue that causes potential discrepancies but the fact that version "numbers" are actually text strings, so comparisons are simple left-to-right operations, exactly as you would compare two words. This means that "1.3.9" is greater than "1.3.10" because "9" > "1". Likewise, considering the recent browser version bump to hundreds, "99" > "102" because "9" > "1".
