Well you could but you would not get what you expect. A query without a relationship creates what's called a "cross-product". So for instance if you have the following 2 tables:
table1
Larry
Sue
John
table2
Apple
Orange
Pear
And you were to include them both in the same query without linking them:
select * from table1,table2
You would get something like:
Larry Apple
Larry Orange
Larry Pear
Sue Apple
Sue Orange
Sue Pear
John Apple
John Orange
John Pear
Mathematically a cross-product returns number of rows as:
table1 rows x table2 rows.
Back to the solution. You may want to create a report that has 2 embedded sub-reports in it, each based on one of your two tables.
Good luck.
