實驗3:利用BBED工具插入行資料
利用BBED工具恢復刪除的行、直接刪除行比較簡單,而透過BBED插入一行資料相對繁瑣,下面透過實驗演示如何插入一行資料。
SQL> select * from perry ;
ID NAME
---------- ----------
1111 aaaa
2222 bbbb
3333 cccc
--下面實驗將新增一行:ID=4444,NAME=dddd
select dump(4444,16) from dual ;
DUMP(4444,16)
---------------------
Typ=2 Len=3: c2,2d,2d
SQL> select dump('dddd',16) from dual ;
DUMP('DDDD',16)
-------------------------
Typ=96 Len=4: 64,64,64,64
SQL> select dbms_rowid.rowid_object(rowid) object_id,
2 dbms_rowid.rowid_relative_fno(rowid) file_id,
3 dbms_rowid.rowid_block_number(rowid) block_id,
4 dbms_rowid.rowid_row_number(rowid) num
5 from perry ;
OBJECT_ID FILE_ID BLOCK_ID NUM
