Message-ID: <3caa866c0802130625k728a4a5dl23bffb56c1ded6e9@mail.gmail.com> (raw)
I want to create and update two tables in a function such as below, but
using parameters as tablename is not allowed and gives an error. Is there
any way I could achieve this?
CREATE OR REPLACE FUNCTION test ( t1 text,t2 text ) RETURNS numeric AS $$
declare temp1 text;
declare temp2 text;
begin
temp1=t1;
temp2=t2;
select
product,
(case when sum(pd) <> 0 then sum(gd)/sum(pd)*100 else 0 end ) as gppp
into temp2 from temp1 as dummy
group by dummy.product,dummy.totalclaimsgroup,dummy.avgmems,dummy.months;
update temp1 as t set
GPPP=(select gppp from temp2 as dummy where dummy.product=t.product),
end
$$ LANGUAGE plpgsql
----------------------
ERROR: syntax error at or near "$1"
LINE 1: ...en sum(gd)/sum(pd)*100 else 0 end ) as gppp from $1 as dum...
^
QUERY: select product, (case when sum(pd) <> 0 then sum(gd)/sum(pd)*100
