There is another solution which I forgot to mention.

select *
  from Table1
  where Col1 not in (select Col1 from Table2)
  and Col2 not in (select Col2 from Table2)
  into Selection

The reason I don't use this is because MapInfo handles these kind of queries
so inefficiently, that when dealing with tables of several thousand records,
the query takes ages (like an hour or more).

I think this would be okay if your tables had a few hundred or less records.

Cheers again,
