You are missing the "end" keyword in there. Also, I'd think this
function is IMMUTABLE not VOLATILE.
CREATE OR REPLACE FUNCTION public.locate(bpchar, bpchar)
RETURNS int4 AS '
-- search for the position of $2 in $1
declare
srcstr alias for $1;
searchstr alias for $2;
begin
return position(searchstr in srcstr);
end;
' LANGUAGE 'plpgsql' IMMUTABLE;
This could also be done as:
CREATE OR REPLACE FUNCTION public.locate(bpchar, bpchar)
RETURNS int4 AS '
select position($2 in $1)
' LANGUAGE 'sql';
HTH,
Joe
