>From what I understand, you can't use complete queries in benchmark, only "expressions". So, what you're actually benchmarking there is setting a string, I guess. You can use it for something like this, though: SELECT BENCHMARK(500000,5 BETWEEN 0 AND 10); and... SELECT BENCHMARK(500000,0 < 5 AND 5 < 10); to see which method MySQL handles faster (between benchmarks faster, although I've always been lead to believe the < and < method is faster). I don't know if i'd really interpret much from the results, though.. ---John Holmes... -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
