• Unnamed parameters in command text -- There is no specification saying whether unnamed parameters should be allowed. Some data providers allow only unnamed parameters, some allow only named parameters (which is the case of the data provider we used in the lecture), some allow both. Unnamed parameters are referenced using question mark in the command text.
