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.
