No problem. Understanding indexes is easy if you imagine trying to find the records yourself. > Just how fast will my Select be? About 110, possibly 130 depending. Your question is meaningless: depends on hardware, OS, number of records, clumpiness of data, whether the records were entered in the order you want them, etc.. Try it and you'll know. > Will it be order(n) with the number of > records being returned? It should not be. Expect it to be more like O(n^.5) or O(log n), but this will be modified by the sizes of perhaps three levels of caching and by how well your OS handles its data.
