Error: PLS-00428: an into clause is expected in this select statement

Question

I\'m trying to create a function as shown below but getting the error stated in the title.

create or replace function gettaxmin(period_tax_type_id in double          


        

Answer 1

You need to store the result INTO result

create or replace function gettaxmin(period_tax_type_id in double precision, tax_range in number) return double precision INTO
Result double precision;
begin
SELECT CASE WHEN max(tax_range) is null THEN 0 ELSE max(tax_range) END 

FROM period_tax_rates WHERE (tax_range < 1) AND (period_tax_type_id = 2);
return(Result);
end gettaxmin;
