Hi,
I have a requirement wherein i have to extract the data for a particular row having DISTINCT COLUMN for the cust_numb

i have been doing the below query:
Code:

  SELECT DISTINCT C1,C2
    FROM TABLE A
    WHERE A.C1  = '123'                 
        ORDER BY C1,C2
 WITH UR;                                                 


The result is as :
Code:

C1     C2
X        1
X        2
Y         1
Y         2
Z         1
A         1
B         2



But now from the above resultant set i need to get only the below rows

Code:

C1     C2
X        2
Y        2
Z        1
A        1
B        2
