Show Field Column Count In A Query

In forms, I frequenty use the following expression to get the results needed from a field's column:
=EmployeeID.column(1).

However, when I try to use the column function in a query it doesn't like it:
EmployeeName:[EmployeeID].Column(1)

What am I doing something wrong?

Along the same line, if I want to use =EmployeeID.column(1) for an unbound control in a form, why must you put the bound field on the form just to get the info? In this case, I want to do this to display the employee's name - not the primary key - without the scroll bar. Every time I do this, Access performance analyser tells me to use fewer controls, but you can't if you have to have the reference. The same thing seems to be required in queries, i.e. include the unaltered control to get an expression.

Help and advise, as always, will be appreciated!
