SELECT DISTINCT causes ORA-03113 only on SQLPlus

• The issue This following query works fine on Toad and PowerBuilder yet when it is run on SQLPlus I get: "ORA-03113: end-of-file on communication channel"

When I remove the distinct from the first line (capitalized below) it runs fine on SQLPlus.

Is there some flag I need to set in SQLPlus to get this to work properly?

• The query in question: SELECT DISTINCT t2.USER_GROUP_ID nn FROM scott.T_XR_CUST t2 ,(SELECT distinct t2.USER_ID FROM scott.T_XR_CUST_ORDER t2 WHERE rownum <= 27526) t8 WHERE t2.USER_ID = t8.USER_ID ;
• The tables I am selecting from create table scott.t_xr_cust (cust_id number(10,0) NOT NULL, ,user_group_id number(10,0) NOT NULL ); Primary key is cust_id.

create table scott.t_xr_cust_order
(cust_id number(10,0) NOT NULL,
,order_id number(10,0) NOT NULL
);
Primary key is cust_id, order_id.
Foreign key constraint exists on the cust_id column and tr_xr_cust.cust_id.
