How do write a Select where you need to join a local (pre-existing) cursor with one or more tables from the Sql Server??

In this example below from my current DBF-based app, lcCsrMtlRecords is a local cursor and I need join it to some lookup values that need to come from my Sql Server database (Jobs and Users).

Select Users.email ;
	From (lcCsrMtlRecords) ;
		Join Jobs On Jobs.job_num = &lcCsrMtlRecords..mat_code ;
		Join Users On Jobs.quoted_by = Users.emp_num ;
	Where qty_recd <> before_qty_recd ;
	Order By 1 ;
	Group By 1 ;
