How to count updated rows after an UPDATE?

Question

Is there a way to count updated rows after an update?
Let's say I have an update like
UPDATE table_a
set field_1 = 'new_field'
WHERE field_2 ='some_value' ;
And now I would like to insert an info record into logging table like
INSERT INTO logging_tbl (step, description, changed_rows) VALUES('UPDATE', 'update of table_a', ?);
update is in sqlplus script.
Thanks.

Use SQL%ROWCOUNT.
DECLARE
  v_num NUMBER := 0;
BEGIN
UPDATE table_a
set field_1 = 'new_field'
WHERE field_2 ='some_value' ;
v_num := SQL%ROWCOUNT;
INSERT INTO logging_tbl (step, description, changed_rows)
VALUES('UPDATE', 'update of table_a', v_num);
END;
