Bulk select with varying values ?

Question

How do we implement bulk collect when the where condition varies ?
Here is a sample code...
I've problems with get_values procedure..
declare
type col1_type is table of number;
type col2_type is table of varchar2(30);
v_col1 col1_type;
v_col2 col2_type;
procedure get_values( p_col1 col1_type, p_col2 in out col2_type ) is
begin
forall j in p_col1.first .. p_col1.last
select col2
into p_col2
from temp2
where col1 = p_col1(j);
end;
begin
select col1, col2 bulk collect into v_col1, v_col2 from temp1;
for i in v_col1.first .. v_col1.last loop
dbms_output.put_line( v_col1(i) || ' ' || v_col2(i));
end loop;
get_values(v_col1, v_col2);
for i in v_col1.first .. v_col1.last loop
dbms_output.put_line( v_col1(i) || ' ' || v_col2(i));
end loop;
end;

Answer 1

But my question was How can we pass an variable which hold multiple values( as shown in the example which is bold) and fetch the return values for all the values in the variable using FORALL OR RETURNING OR BULK COLLECT.
declare
type col1_type is table of number;
type col2_type is table of varchar2(30);
v_col1 col1_type;
v_col2 col2_type;
procedure get_values( p_col1 col1_type, p_col2 in out col2_type ) is
begin
/* How can we implement this using bulk without looping through each element of the variagle p_col1. I know it can done using for j in p_col1.first .. p_col1.last
loop ............ end loop; */
forall j in p_col1.first .. p_col1.last
select col2
into p_col2
from temp2
where col1 = p_col1(j);
end;
begin
select col1, col2 bulk collect
into v_col1, v_col2
from temp1;
for i in v_col1.first .. v_col1.last loop
dbms_output.put_line( v_col1(i) || ' ' || v_col2(i));
end loop;
get_values(v_col1, v_col2);
for i in v_col1.first .. v_col1.last loop
dbms_output.put_line( v_col1(i) || ' ' || v_col2(i));
end loop;
end;
