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);
insert into 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 DISTINCT is
specified.

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