Hello.
Usually the execution time is measured on the client side (you may implement it in your application). I don't know how to measure the number of I/O operations involved by a single query. There is only a global statistics reported by SHOW STATUS. There is a handy tool in MySQL - EXPLAIN statement. See: http://dev.mysql.com/doc/mysql/en/show-status.html http://dev.mysql.com/doc/mysql/en/explain.html "qin lei" <[EMAIL PROTECTED]> wrote: > I need know the execution time of a query.
