CHANGES

upgrade to 11.2.0.4

CAUSE

The issue have been investigated in the following bug:

Bug:17655864 - ORA-01791: NOT A SELECTED EXPRESSION AFTER 11.2.0.4 PATCH

which is closed as not a bug. and this is expected behvior .

so the correct behavior is on 11.2.0.4 and not older versions.

This is due to

BUG 13768663 - SELECT WORKS IN 10.2 AND 11.2.0.3 FAILS 11.1.0.7 ORA-01791

Invalid query which should raise ORA-1791 is working fine without any error starting from 11.2.0.1.This is fixed in 11.2.0.4 and hence you may get the error ORA-1791 in 11.2.0.4.

SOLUTION

The expected behaviour for this statement is that it should report ORA-01791 That is, this is a select DISTINCT query and the order by column does not reference a select list item. This is a documented restriction of the order by clause.

http://docs.oracle.com/cd/E11882_01/server.112/e10592/statements_10002.htm#SQLRF20039

This behaviour is corrected through bugfix 13768663.

so please add the orderby column in the select statement

SQL> select distinct sal, empno, deptno from scott.emp order by deptno;

SAL EMPNO DEPTNO
