"Where in "employee INNER JOIN order ON order.employee_id = employee.id" is there a need for additional qualification?".
There is no need for additional qualification because the qualification I talked of is already there.
"the reason that a business user refers to Order ID or Employee ID is to provide context, but at a dabase level you already have context because you are refereing to the table".
Pray, tell me, if the column is named 'ID', then how is that "refereing [sic] to the table" done exactly, unless by qualifying this reference to the ID column exactly in the way I talked of ?
