create or replace function NJUTEC_GETNDKHSCORE(identity in varchar2) return number is
Result number;
CNTS NUMBER:=0;
begin
SELECT COUNT(1) INTO CNTS
FROM person_ndkh_info t WHERE T.IDENTIFY=identity;
if (CNTS>=5) then
RESULT:=(CNTS*1)+5;
elsif (CNTS>0) then
RESULT:=CNTS*1;
ELSE
RESULT:=0;
end if;
return(Result);
end NJUTEC_GETNDKHSCORE;
自定义函数里多if判断
