It shouldn't be hard to do, I hope.
What I want to do is this:
select table1.id from table1,table2 where table1.id != table2.id .... I wish it was possible to write like that... but it doesn't I guess I can figure out the reason but anyway how should I do it? PLEAse help... example:
table1 table2
id 1 id2
id 2
id 3
select table1.id from table1,table2 where <what to write here?>
result:
id 1
id 3
