Hi All,

         I've the following qry :

select
distinct(decode(b.sys_id,'TRDENG',a.cust_bas_no,a.cosmos_base_no)) baseno ,a.br_cod,pty_nam,bank_name
from piar_fr_psd a, psd b, bank_br c
where a.psd_id=b.psd_id
and a.psd_serial_num = b.psd_serial_no
and b.bank_id = c.bank_id
and (((sys_id = 'TRDENG') and (a.cust_bas_no is not null)) or ((sys_id <> 'TRDENG') and (a.cosmos_base_no is not null)))

o/p :
baseno br_cod pty_nam bank_name

 1        10     x1     y1
 1        10     x111   y1
 1        10     x1334  y1
 2        20     x212   y2
 2        20     x213   y2

For a baseno,br_cod combination I need only one row to be displayed. i.e any one pty_nam should be displayed .

o/p :

baseno br_cod pty_nam bank_name

 1        10     x1     y1
 2        20     x213   y2

How can I achieve this.

Thanks
Manoj
