Full Discussion: mysql query all entries which 'dont' match
Special Forums UNIX and Linux Applications mysql query all entries which 'dont' match Post 302304278 by hazno on Monday 6th of April 2009 03:43:28 AM

mysql query all entries which 'dont' match
I am trying to query a list of hosts and extract all entries which 'dont' match.

Code:
SELECT LOGS.host, GOODLIST.host FROM LOGS,db.GOODLIST WHERE (LOGS.host <> GOODLIST.host)

When I use this query, it is very very slow. Matching the host with the GOODLIST.host works great and fast but when I use <> to get the hosts which DONT match, it doesnt work as expected. Am I using the wrong approach?

thanks & regards

rup(1)								   User Commands							    rup(1)

NAME

       rup - show host status of remote machines (RPC version)

SYNOPSIS

       rup [-hlt]

       rup [host...]

DESCRIPTION

       rup gives a status similar to uptime for remote machines. It broadcasts on the local network, and displays the responses it receives.

       Normally,  the  listing	is in the order that responses are received, but this order can be changed by specifying one of the options listed
       below.

       When host arguments are given, rather than broadcasting rup will only query the list of specified hosts.

       A remote host will only respond if it is running the rstatd daemon, which is normally started up from inetd(1M).

       In the absence of a name service, such as LDAP or NIS, rup displays host names as numeric IP addresses.

OPTIONS

       -h	Sort the display alphabetically by host name.

       -l	Sort the display by load average.

       -t	Sort the display by up time.

ATTRIBUTES

       See attributes(5) for descriptions of the following attributes:

       +-----------------------------+-----------------------------+
       |      ATTRIBUTE TYPE	     |	    ATTRIBUTE VALUE	   |
