Hi Not sure about $1 parms : you may need to use a variable to set $1 to then cast it as interval :
create or replace function test(integer) returns setof text as $$
declare
a record;
begin
select into a now() - ($1::text||'days')::interval;
return next a;
return;
end
$$ language 'plpgsql';

How should this be properly quoted
create or replace function test(integer) returns setof text as $$
declare
a record;
begin
select into a now() - interval '$1 day';
return next a;
return;
end
$$ language 'plpgsql';
I'm not having a lot of luck
Thanks
Richard
