Cursor as parameter

Question

How I can paste cursor as parameter?
I am trying to paste cursor variable1 as a parameter in cursor variable2, but I'm getting error: PLS-00488: invalid variable declaration: object 'VARIABLE1' must be a type or subtype.
This is the code:
DECLARE
CURSOR variable1 IS SELECT DEPARTMENT_ID from EMPLOyees;
CURSOR variable2 (vvar variable1) IS SELECT FIRST_NAME,LAST_NAME from EMPLOyees where DEPARTMENT_ID=vvar;
BEGIN
OPEN variable1;
for j in variable1 loop
OPEN variable2 (j.DEPARTMENT_ID);
for i in variable2 loop
dbms_output.put_line(i.First_name ||' '||i.LAST_NAME);
END loop;
END loop;
end;

What you are doing is not correct.And what you are showing in your code is also wrong.
Why are you manually coding a nested loop join in PL/SQL. Why are you not using SQL and have it doing the join instead?
PL/SQL is slower than SQL when it comes to processing SQL data.
There is a very basic rule that describes this:
Maximize SQL. Minimize PL/SQL+
In other words, do not reinvent the wheel using PL/SQL - use SQL to its full capabilities. That ensures performance and scalability.
