What's the advantage of using PUT over INSERT? Under what circumstances can you see the affect? What's the disadvantage? 2. What's a cursor? 3. In a given table, if you had a variety of sorting needs based on three different columns in various combinations (colA, colA+colB, colA+colB+colC, colB, colB+colC, colC), how many indexes would you create? Why? If the dude was in front of you -- 4. Write a short code segment (in a metalanguage if you'd like) that, given some typed in select statement by the user, executes the query and displays the result. There's a whole bunch of questions you could ask and I could list, but I tire easily. Ask loaded questions that will tell you a LOT from each response. --- -- Jerry
