Returning multiple values from a PL/SQL FUNCTION.

Suppose I have a table XX_TEST which has two columns ID(number) and NAME(varchar2(20))

It has following values:-

ID  NAME

1 RJ

1 NJ

2 AJ

2 PJ

Now I want to create a PL/SQL FUNCTION which has 1 parameter say P_ID.

where if I pass P_ID value as 1 then it should return values as RJ and NJ.

and if I pass P_ID value as 2 it should return AJ and PJ. 

Kindly suggest.
