So, what does the specification tells about seeds, normal and random functions? A bunch of DBMSs implement RAND, sometimes RANDOM, SEED or even NORMAL using from time to time specific SQL keywords to do the work. Note that SQLValueFunction made the addition of more returning data types a bit more complicated (not much, still) than the new COERCE_SQL_SYNTAX by going through a mapping function, so the keyword/function mapping is straight-forward. -- Michael
