1. @/home/oracle/FY_Recover_Data.SQL
创建需要的package
[oracle@localhost oradata]$ sqlplus / as sysdba

Package created.
Package body created.
2. 创建测试数据：
create table scott.test_emp tablespace users as select * from scott.emp;
truncate table scott.test_emp
3. 执行脚本：
注意路径：“/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/'; --必须和test.t1表所在的数据文件的目录相同
datadir := 'FY_DATA_DIR'; --oracle中目录的名字，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;
执行完成之后，会看到scott用户下多了表：
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
