There is an optimization that can allow inserts (note: not updates) and selects to happen at the same time, which may be what you are seeing. There are lots of corner cases, etc. so your best bet is to check out the documentation which does a reasonable job of explaining them, in particular: http://dev.mysql.com/doc/mysql/en/Internal_locking.html http://dev.mysql.com/doc/mysql/en/Table_locking.html -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe: http://lists.mysql.com/[EMAIL PROTECTED]
