1. But what are you doing?
2. There are 2 different outputs for the same input column values.
3. What are B3,A3,C3?
4. Use SQL*Plus to post the complete session output.
Please specify the RULES to generate the output.

Nothing could be concluded without knowing the RULES to generate the output.

Hi Lalit/Dariyoosh,
Thanks for getting back. Here what I am trying to achieve.
I have table with data something like in the column.
ALPHA_B3_TRAN,ALPHA_A3_PROD,ALPHA_C3_FX,ALPHA_B3_ACCT,ALPHA_D3_PRICE
ALPHA_B3_TRAN,ALPHA_B3_PROD,ALPHA_B3_FX,ALPHA_B3_ACCT,ALPHA_B3_PRICE
ALPHA_A2_PROD,ALPHA_X3_FX,ALPHA_X3_ACCT
ALPHA_D3_ACCT,ALPHA_S3_PRICE
ALPHA_P3_TRAN,ALPHA_P5_PRICE
I would like to query this column to get the output as
B3,A3,C3,D3
B3
A2,X3
D3,S3
P3,P5
If the value between two underscore is appearing multiple times, the it should be printed only once. In the above example for row 2, B3 should appear in output only once.
Lalit- I thought of using REGEXP_SUBSTR but it started showing the value between first and last underscore. Since not much exposure to REGEXP_SUBSTR finding it difficult.
