Instructions. Turn the power on to your stereo unit. Place the cassette tape into the deck and make sure to rewind it all the way on side A. Now that you have a fresh tape to start with, change the function on your stereo to CD.
Qualify(verb) to make such as is required; to give added or requisite qualities to; to fit, as for a place, office, occupation, or character; to furnish with the knowledge, skill, or other accomplishment necessary for a purpose; to make capable, as of an employment or privilege; to supply with legal power or capacity.
With qualify, identical expressions are allowed before and after the qualify step, but they give different results with and without the qualify clause. Your explanation of what the query with qualify means isn't clear. Windowed functions aren't allowed in the WHERE clause because they can lead to ambiguity or at least surprise (row numbers not starting at 1, for example), so defining QUALIFY in terms of a disallowed WHERE clause doesn't resolve the problem.
