Replace a Character in the Query output..

Question

Hi all,
I have a query which returns an output like the following
Field 1
29-0138392-00200
29-0138392-00200
29-0138392-00200
21-1774692-00210
21-1774692-00210
21-1774692-00210
21-1774692-00304
21-1774692-00304
I want to format it into as follows
29-0138392-A0200
29-0138392-B0200
29-0138392-C0200
29-0138392-D0200
21-1774692-A0210
21-1774692-B0210
21-1774692-C0210
21-1774692-A0304
21-1774692-B0304
How to Acheive this....?

Answer 1

I have got little bit different table but result should be the same:
      COL1 COL2       COL3
         1 S1         13/01/2006
         1 S2         13/01/2006
         1 S1         14/01/2006
         2 S1         13/01/2006
         2 S2         13/01/2006
         2 S1         14/01/2006
6 rows selected.I would like to add to col1 letters.
I wrote this query:
  1  SELECT B1.COL1, B2.COL1, CASE WHEN RN > COUNT THEN
  2                             CHR(64 + (RN - COUNT)) || B1.COL1 ELSE CHR(64 +
RN) || B1.COL1 END AS RESULT, COUNT
  3  FROM (SELECT COL1, ROWNUM AS RN
  4     FROM TABLEB) B1,
  5       (SELECT COL1, COUNT(1) AS COUNT
  6     FROM TABLEB
  7     GROUP BY COL1) B2
  8* WHERE B1.COL1=B2.COL1;And the effect:
      COL1       COL1 RESULT                                            COUNT
         1          1 A1                                                    3
         1          1 B1                                                    3
         1          1 C1                                                    3
         2          2 A2                                                    3
         2          2 B2                                                    3
         2          2 C2                                                    3
6 rows selected.As you can see RESULT column has values from COL1 and letter in front of it starting from A to ROW COUNT.
Hope this help
