没有提到甲骨文版本。 (关于最佳答案,always包括Oracle版本、Oracle edition、OS和OS版本)。)
但是,你应为此目的利用外部表格进行调查。 一旦你正确设立,你就可以:
insert into db_table select ... from external_table;
Optionally, you could use the APPEND
hint on the INSERT
statement, to use direct load.
Also,optionally, you could set the NOLOGGING
attribute on the table you re loading the data into, for best performance. But, consider the recovery implications before you enable NOLOGGING
.
