2.      創(chuàng)建測試數(shù)據(jù)：
create table scott.test_emp tablespace users as select * from scott.emp;
truncate table scott.test_emp

3.      執(zhí)行腳本：
注意路徑：“/u01/app/oracle/oradata/orcl/”最后的”/”不能缺少
DECLARE

  tgtowner VARCHAR2(30);

  tgttable VARCHAR2(30);

  datapath VARCHAR2(4000);

  datadir  VARCHAR2(30);

  rects    VARCHAR2(30);

  recfile  VARCHAR2(30);

  rstts    VARCHAR2(30);

  rstfile  VARCHAR2(30);

  blksz    NUMBER;

  rectab   VARCHAR2(30);

  rsttab   VARCHAR2(30);

  copyfile VARCHAR2(30);

BEGIN

  tgtowner := 'SCOTT'; --table owner

  tgttable := 'TEST_EMP'; --table name

  datapath := '/u01/app/oracle/oradata/orcl/'; --必須和test.t1表所在的數(shù)據(jù)文件的目錄相同

  datadir  := 'FY_DATA_DIR'; --oracle中目錄的名字，可以修改

  fy_recover_data.prepare_files(tgtowner,

                                tgttable,

                                datapath,

                                datadir,

                                rects,

                                recfile,

                                rstts,

                                rstfile,

                                blksz);

  fy_recover_data.fill_blocks(tgtowner,

                              tgttable,

                              datadir,

                              rects,

                              recfile,

                              rstts,

                              8,

                              tgtowner,

                              tgtowner,

                              rectab,

                              rsttab,

                              copyfile);

  fy_recover_data.recover_table(tgtowner,

                                tgttable,

                                tgtowner,

                                rectab,

                                tgtowner,

                                rsttab,

                                datadir,

                                datadir,

                                recfile,

                                datadir,

                                copyfile,

                                blksz);

 

END;

執(zhí)行完成之后，會看到scott用戶下多了表：
SQL> select table_name, tablespace_name from dba_tables where owner = 'SCOTT';

 

TABLE_NAME                             TABLESPACE_NAME

------------------------------ ------------------------------

DEPT                                             USERS

EMP                                              USERS

BONUS                                         USERS

SALGRADE                                   USERS

TEST_EMP$                                 FY_REC_DATA

TEST_EMP$$                              FY_RST_DATA

TEST_EMP                                   USERS

 

7 rows selected.

將TEST_EMP$$插回TEST_EMP
