SQL> drop table t; drop table t * ERROR at line 1: ORA-55610: Invalid DDL statement on history-tracked table
情况分析
置于Flashback data archive中的table的一些限制 追踪表(Tracked table),也就是指定将历史数据保存到某个flashback data archive中的table,不能执行DDL操作(add column除外)。 NING@11g>drop table test; drop table test * ERROR at line 1: ORA-55610: Invalid DDL statement on history-tracked table NING@11g>truncate table test; truncate table test * ERROR at line 1: ORA-55610: Invalid DDL statement on history-tracked table NING@11g>alter table test drop column object_id; alter table test drop column object_id * ERROR at line 1: ORA-55610: Invalid DDL statement on history-tracked table NING@11g>alter table test add col_test int; Table altered. 但是可以rename table,这一点和文档上说的不一致 NING@11g>rename test to test1; Table renamed. NING@11g>select table_name,flashback_archive_name from dba_flashback_archive_tables; TABLE_NAME FLASHBACK_ARCHIVE_NAME —————————— —————————— TEST1 TEST_ARCHIVE1
解决方案
SQL> alter table emp no flashback archive; Table altered. SQL> alter table t no flashback archive; Table altered. SQL> alter table NETSTORE_INCOMEEXPENDITURELIST no flashback archive; Table altered.
再次执行导出schema操作

如何将已经纳入数据归档区的表解除闪回数据归档?
SQL> alter table emp no flashback archive; Table altered.
解除之后,再次进行DDL操作(DROP等),就不会报错
SQL> drop table t; Table dropped.
