Can someone tell me why I would use a query adapter within the dataset designer instead of adding queries to the table adapter?

Sometimes your queries do not need to be associated with an actual DataTable. Perhaps you have a Query that is logically grouped within your DataSet, but has no real backing store.
For Instance, suppose you wanted to call a stored procedure that safely deletes all associated records for a given customer:
This really doesn’t belong to any one particular entity as it might span multiple tables, but still belongs in your CustomerDataSet.
