Q

How To Use "FOR" Loop Statements in Oracle?

A

If you have a block of codes to be executed repeatedly over a range of values, you can use the "FOR ... LOOP" statement. Here is a sample script on FOR statements:

DECLARE
  total NUMBER := 0;
BEGIN
  FOR i IN 1..10 LOOP
    total := total + i;
  END LOOP;
  DBMS_OUTPUT.PUT_LINE('Total: ' || TO_CHAR(total));
END;

Note that temporary variable "i" used in the FOR loop needs no declaration. This script should print this:

Total: 55
