I'm at LCA, and am going to go to the MySQL BOF, the topic of which is optimisation. I probably should have asked earlier, but has anyone got some stuff which they want me to bring up? I've already got some nice hints I'll write up later, but they require MySQL 4.0 (or 4.1 - which will support all teh subselect stuff we want, but isn't yet stable). We really should up the minimum version sometime soon.... Bradley
