ORACLE update with returning OLD and NEW values

Is there equivalent to this T-SQL query in PL/SQL (Oracle 12c)?

UPDATE A SET A.columnA = 10 WHERE A.columnB < 30 OUTPUT INSERTED.*, DELETED.*

The query updates table A and at the same time returns the status of the record before the update and after the update.

Trigger is not a solution for me as well as SELECT records before and SELECT records after updating.

Solution 1:

Not a direct one, but using RETURNING INTO you will be able to achieve the same effect:

CREATE TABLE A(columnA VARCHAR2(10), columnB INT);
INSERT INTO A(columnA, columnB) VALUES ('Test', 10);
INSERT INTO A(columnA, columnB) VALUES ('Row 2', 20);
CREATE TABLE audit_table(col_new VARCHAR2(10),col_old VARCHAR2(10));

DECLARE
   TYPE rec IS RECORD (actual A.columnA%TYPE, old A.columnA%TYPE);
   TYPE col_a_t IS TABLE OF rec;
   v_a col_a_t;
BEGIN
  UPDATE (SELECT A.*, (SELECT A.columnA FROM dual) AS old_columnA FROM A)
  SET columnA = 'XYZ'
  WHERE columnB < 30
  RETURNING columnA, old_columnA BULK COLLECT INTO v_a;
  COMMIT;

  -- printing for debug
  FOR i IN v_a.first .. v_a.last LOOP
     dbms_output.put_line('Old =>' || v_a(i).old || ' new => ' || v_a(i).actual);
  END LOOP;

  -- additional
  FORALL i IN v_a.first .. v_a.last
    INSERT INTO audit_table VALUES v_a(i);
  COMMIT;
END;
/

SELECT * FROM A;
SELECT * FROM audit_table;
