这样写合呼语法吗？
create or replace function f_stat
(
date_startime in date,
in_item in int)

RETURN float IS
return_value float;

declare
in_callnum int;
in_StatusA int;

BEGIN

case in_item
when 1 then return_value := 3
when 2 then return_value := 8
else return_value := 0
end;

end;

不符合

可以用 if ... then .. end if;
