Welcome to the real world, Josh. There are people who
have full time salaried positions soley to attend
standards meetings.
Note that ROW_NUMBER() really is handy, regardless of the
silly name. And there was a little python function of mine
that did it fairly simply, except that you needed to
initialize the counter in the connection before use.
create or replace function pycounter(integer)
returns integer as
' if args[0] == 0: SD["nextno"] = 1 return SD["nextno"] try: SD["nextno"] += 1 except: SD["nextno"]
=1 return SD["nextno"]
' language 'plpythonu';
And clearly it can be done faster as a little
C function.
