A

Right after executing a DML statement, you retrieve any attribute of the implicit cursor by using SQL%attribute_name, as shown in the following tutorial exercise:

CREATE TABLE student (id NUMBER(5) PRIMARY KEY,
  first_name VARCHAR(80) NOT NULL,
  last_name VARCHAR(80) NOT NULL);
Table created.

DECLARE
  id NUMBER;
  first_name CHAR(10);
BEGIN
  id := 29;
  first_name := 'Bob';
  INSERT INTO student VALUES(id, first_name, 'Henry');
  first_name := 'Joe';
  INSERT INTO student VALUES(id+1, first_name, 'Bush');
  DBMS_OUTPUT.PUT_LINE('# of rows inserted: '
    || SQL%ROWCOUNT);
 
  first_name := 'Fyi';
  UPDATE student SET first_name = first_name WHERE id = 29;
  IF SQL%FOUND THEN
      DBMS_OUTPUT.PUT_LINE('# of rows updated: '
        || SQL%ROWCOUNT);
  END IF;

  UPDATE student SET first_name = first_name
    WHERE id = id+1;
  IF SQL%NOTFOUND THEN
    DBMS_OUTPUT.PUT_LINE('No records updated.');
  END IF;
    
  DELETE FROM student WHERE id = id;                    
  DBMS_OUTPUT.PUT_LINE('# of rows deleted: '
    || SQL%ROWCOUNT);
END; 
/
# of rows inserted: 1
# of rows updated: 1
No records updated.
# of rows deleted: 2
