In the discussion about multiple row insert into the Oracle two approaches were demonstrated:
insert into pager (PAG_ID,PAG_PARENT,PAG_NAME,PAG_ACTIVE) select 8000,0,'Multi 8000',1 from dual union all select 8001,0,'Multi 8001',1 from dual
INSERT ALL INTO t (col1, col2, col3) VALUES ('val1_1', 'val1_2', 'val1_3') INTO t (col1, col2, col3) VALUES ('val2_1', 'val2_2', 'val2_3') INTO t (col1, col2, col3) VALUES ('val3_1', 'val3_2', 'val3_3') . . . SELECT 1 FROM DUAL;
Could anyone argue the preference of using one over another?
P.S. I didn't do any research myself (even explanation plan), so any information or opinion would be appreciated.
