They are "bit strings" after all, not binary numbers. If you need a binary number, use any numeric type and format the input and output accordingly. As for converting between bit strings and numbers, maybe we should make pairs of explicit functions that assume one bit order or another, and remove the casts. All things considered, it was probably a good idea that they removed bit strings in SQL200x. -- Peter Eisentraut peter_e@gmx.net
