    Status variables not updating?


    Hi, I have noticed that my status variables are not updating. For example, if I do a simple select query many times on a table, SHOW STATUS reports that the Com_select = 0. As a matter of fact almost all variables are 0 or very low.

    I am running a fresh install of a MySql 5.0 binary distribution, un-tar-red - not installed via yum (mysqld runs 5.0). In case you're interested, yum will still report that I have the following installed:
    mysql.i386 4.1.11-2 installed
    mysql-devel.i386 4.1.11-2 installed
    mysql-server.i386 4.1.11-2 installed
    mysqlclient10.i386 3.23.58-6 installed

    The following is the output of SHOW STATUS:

    Fix: SHOW GLOBAL STATUS

    Ok, mysql 5.0 has introduced a couple of new keywords.
