(2)許可權
flashback archive administer privilege

create user test identified by test default tablespace users;

grant connect,resource to test;

grant flashback archive administer to test;

(3)建立閃迴歸檔
create flashback archive flash1
tablespace users
quota 10m
retention 1 year;

SQL> col owner_name for a10
SQL> col flashback_archive_name for a20

SQL> select owner_name,flashback_archive_name,FLASHBACK_ARCHIVE#,RETENTION_IN_DAYS,status from  dba_flashback_archive;

OWNER_NAME FLASHBACK_ARCHIVE_NA FLASHBACK_ARCHIVE# RETENTION_IN_DAYS STATUS
---------- -------------------- ------------------ ----------------- -------
TEST       FLASH1                                1               365

SQL> col tablespace_name for a10       
SQL> select flashback_archive_name,tablespace_name,quota_in_mb from dba_flashback_archive_ts

FLASHBACK_ARCHIVE_NA TABLESPACE QUOTA_IN_MB

(4)建立閃迴歸檔表
create table t(name varchar2(30),address varchar2(50))
flashback archive flash1;

SQL> col table_name for a10
SQL> col archive_table_name for a20
SQL> select * from dba_flashback_archive_tables

TABLE_NAME OWNER_NAME FLASHBACK_ARCHIVE_NA ARCHIVE_TABLE_NAME   STATUS
---------- ---------- -------------------- -------------------- --------
T          TEST       FLASH1               SYS_FBA_HIST_74484   ENABLED

(5)查詢閃回記錄
