RE: Convert block dump data (data type number)

Hi

You could use dbms_stats package also.

declare

   n1 number;

begin

  dbms_stats.convert_raw_value('&&rawvalue', n1);

  dbms_output.put_line (n1);

end;

/

SQL> / old 4: dbms_stats.convert_raw_value('&&rawvalue', n1);

new 4: dbms_stats.convert_raw_value('c24a46', n1);

7369

Hi

I have dumped a block and trying to see the data it contains, for the varchar2 it's quite simple we simply convert hex to ascii but for number I cant find a suitable way, does anyone know how to convert this data?

select

   dbms_rowid.rowid_to_absolute_fno(rowid, 'SCOTT', 'EMP') ABS_FNO,
   dbms_rowid.rowid_relative_fno(rowid) REL_FNO,
   dbms_rowid.rowid_block_number(rowid) BLOCKNO,
   dbms_rowid.rowid_row_number(rowid) ROWNO,

   ABS_FNO REL_FNO BLOCKNO ROWNO EMPNO ENAME ---------- ---------- ---------- ---------- ---------- ----------

         8 8 10 0 7369 SMITH so I dump block 10 and check for row 0 and got this:

tab 0, row 0, @0xb94
tl: 38 fb: --H-FL-- lb: 0x0 cc: 8

col  0: [ 3]  c2 4a 46 --> EMPNO
col  1: [ 5]  53 4d 49 54 48 --> ENAME
col  2: [ 5]  43 4c 45 52 4b
col  3: [ 3]  c2 50 03
col  4: [ 7]  77 b4 0c 11 01 01 01
col  5: [ 2]  c2 09
col  6: *NULL*
col  7: [ 2]  c1 15

so converting 53 4d 49 54 48 to ascii we got SMITH but to get the EMPNO (7369) using c2 4a 46 ?

TIA Alex
