Hi Mike,

>That may be so, but I really have to ask, why not do it the optimal way the first time?

I know you're obsessed with these kind of optimizations, but what is optimized really depends on the population. For only two records having an index lookup really means LESS performance compared to a table scan.

As all in software development. If there is a performance problem, try to take it out. It really does not make sense to spend a lot of time to optimize each and every program line in a project.

Programming from a performance pov is only neccesary if you expect that piece of software to be susceptible to performance problems. Otherwise don't bother, your time is not worth it.

Walter,
