I have a separate "Query Manager" class that I use for this kind of thing. In my framework, a business object usually handles not just one table (though it can), but a parent table and its children. I use these objects in combination with a data object for CRUD operations. The Query Manager can execute complete SQL SELECT query statements that are passed to it, or can assemble a query from passed parameters (fields clause, FROM clause, WHERE clause, etc.). I use this to get lookup data, lookup lists, and for reports.
