Re: [HACKERS] distinct. Is this the correct behaviour?

Using the following script...
   create table t1(f1 int, f2 int);   insert into t1(f1, f2) values(1,1);   insert into t1(f1, f2) values(1,2);
insertinto t1(f1, f2) values(1,3);   insert into t1(f1, f2) values(2,4);   select distinct f1 from t1 order by f2;
 


Returned the following message under Oracle8 on NT:   ORA-01791: not a SELECTed expression

Returned the following message under MS SQL Server 7.0:   ORDER BY items must appear in the select list if SELECT
DISTINCTis
 
specified.

I could try it on Oracle8i but I suspect the result will be the same.
