You can run queries (SELECT statements) in a PL/SQL code blocks, and process the results a loop as shown in the following script example:

SQL> set serveroutput on;

SQL> BEGIN
  2     FOR row IN
  3         (SELECT * FROM employees WHERE manager_id = 101)
  4         LOOP
  5       DBMS_OUTPUT.PUT_LINE('Name = ' || row.last_name);
  6     END LOOP;
  7  END;
  8  /
Name = Greenberg
Name = Whalen
Name = Mavris
Name = Baer
Name = Higgins

The loop statement in this script automatically sets a temporary variable "row" each row in the result set returned from the SELECT statement.
