No. The trick is common in many computer languages and I've never seen a good formulaic way of doing that. You generally see that the programmer has picked some high-placed character. It provides /huge/ increases in speed in big databases so it can be worth doing, but it may not make a big difference in your case. > Will this work without using the BETWEEN statement you describe above ? In SQLite a BETWEEN b AND c is exactly equivalent to a >= b AND a <= c In fact I believe that the substitution is made at the parsing level rather than involving low-level changes to planning. So you can just consider it two separate restrictions.
