Re: function error

Doh! Sorry my code DOES have the FOR in it as does the example in the
book. Neither works though.

My apologies this was my second attempt w/o the FOR.

Here's what I really have:

CREATE FUNCTION biwklyavg(text, text, text) RETURNS numeric AS '
DECLARE
system ALIAS FOR $1;
startdate ALIAS FOR $2;
enddate ALIAS FOR $3;
result numeric;

BEGIN
result := (select (avg(usr) + avg(sys)) from sardata
where
systemid = system and time between startdate and enddate;
END;
' LANGUAGE 'sql';

Needs a FOR!!

system ALIAS FOR $1;

Strange that the sample is wrong?
