MySQL Error 1054 In Where Clause
===

The following SQL query has been giving me fits:

    DELETE FROM zNMall1r.* WHERE zNMall1r.Phone = DoNotCall.Phone

When I attempt to execute, it returns Error 1054:

    17:51:01	DELETE zNMall1r.* FROM zNMall1r WHERE zNMall1r.Phone = Phone.DoNotCall	
    Error Code: 1054. Unknown column 'Phone.DoNotCall' in 'where clause'	0.078 sec

Anybody have thoughts on this?
