Oracle에서 한 문장으로 여러 행을 삽입하는 방법으로 옳지 않은 것은?

1. 1INSERT INTO t (c1, c2) VALUES (1, 'A'), (2, 'B'), (3, 'C')
2. 2INSERT ALL INTO t VALUES (1, 'A') INTO t VALUES (2, 'B') SELECT * FROM DUAL
3. 3INSERT INTO t (c1, c2) SELECT id, name FROM src
4. 4INSERT WHEN c1 > 0 THEN INTO t1 ELSE INTO t2 SELECT * FROM src (Conditional Multi-Table)
