How To Retrieve the Count of Updated Rows?

After running an UPDATE statement, the database server returns a count of updated rows. You can retrieve this count from a special predefined variable called SQL%ROWCOUT, as shown in the following tutorial:

CREATE TABLE emp_temp AS SELECT * FROM employees;

BEGIN
  UPDATE emp_temp SET salary = salary * 1.05
    WHERE salary < 5000;
  DBMS_OUTPUT.PUT_LINE('# of rows updated: ' ||
    SQL%ROWCOUNT);
END;
/
# of rows updated: 49
