我正在尝试从oracle转储中导入特定的表,为了避免任何父键未找到异常,我想按照某个顺序导入表。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
此命令会保证在X之前导入A和B吗?
答案 0 :(得分:4)
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上指定的顺序不保证导入表的顺序,它是按照导出的顺序完成的。
