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.
