Do you want to combine the crosstabs vertically (a union query) or
horizontally (a join of some type)?
For example.
Crosstab A returns these columns
A x1 x2 x3
Crosstab B returns these columns
A b1 b2 b3 b4
Do you want to end up with the following?
A x1 x2 x3 null
A b1 b2 b3 b4
Or do you want to end up with the following?
A x1 x2 x3 b1 b2 b3 b4
If you want the first option, you are going to have to specify the columns
returned by the crosstabs in order to use a union query.
If you want the second option, you may have to specify the columns returned
depending on which column(s) you are going to use in the join.
