oracle - 从 oracle 转储导入时表的顺序是否相关？

Question

我正在尝试从 oracle 转储中导入特定的表，为了避免任何未找到父键的异常，我想按照一定的顺序导入表。例如，如果表 X 依赖于表 A 和 B，我想先导入 A 和 B:

imp user/pass@dbName tables=(A,B,X) rows=y ignore=Y 

这个命令能保证 A 和 B 在 X 之前导入吗？

exp userid=ronr tables=COMM_SCHEDULE_DELIVERY,COMM_SCHEDULE_DETAIL,COMM_SCHEDULE_HEADER file=z.dmp

imp userid=imp fromuser=ronr touser=imp tables=COMM_SCHEDULE_HEADER,COMM_SCHEDULE_DETAIL,COMM_SCHEDULE_DELIVERY file=z.dmp

不，在 imp 上指定的顺序并不能保证表的导入顺序，它是按照它们导出的顺序完成的。
