Makes sense to me.

I have a query that I think is behaving oddly; and, it may just be that I'm blind and am doing something silly (*there's* a first!), or it may be environment specific, but, I'm thinkin it may just be a bug. I have filed a TAR with Oracle, and they keep sending workarounds, when I told them from the start that I've got one, this is only a question of why this query isn't working. So, two parts, really... is this query really not working, and if so, does anyone have a clue as to why? We're on 9.2.0.2 on SunOS. The overall issue is easy. I have two tables. I want to find the difference in the contents. This is easily accomplished by doing A MINUS B UNION B MINUS A *That's* not the issue. The issue is that if I do this through inlines, the query fails. I'll put everything out there so you can just cut and paste iffen you wanna... SQL> create table junk (test char(1)); Table created. SQL> insert into junk values ('A'); 1 row created. SQL> insert into junk values ('B'); 1 row created. SQL> insert into junk values ('C'); 1 row created. SQL> create table junk2 as select * from junk; Table created. SQL> insert into junk2 values ('X'); 1 row created. SQL> select * from junk; T - A B C SQL> select * from junk2; T - A B C X SQL> select * from junk minus select * from junk2 2 union 3 select * from junk2 minus select * from junk; T - X SQL> select a.* 2 from 3 ( select * from junk2 minus select * from junk ) a; T - X SQL> select a.*, b.* 2 from 3 ( select * from junk2 minus select * from junk ) a, 4 ( select * from junk2 minus select * from junk ) b; T T - - X X SQL> select a.*, b.* 2 from 3 ( select * from junk minus select * from junk2 ) a, 4 ( select * from junk2 minus select * from junk ) b; no rows selected Anyone?
