I meant rather than using MS SQL Server. If you are just asking the plain old which version, the MySQL version is running 4.0.18 and is allegedly running the mysqld-max-nt.exe build. > For SELECT speed of a mostly static table, MyISAM. For all other reasons InnoDB. Given this info, for this table, MyISAM is the better choice... > Does this query ever return more then one row? I.e. can a dotlessIP be in more ranges? No, it only ever returns a single row.
