Here how I created the table:
CREATE TABLE syslogTB (
facility char(10), # OPTIONAL field for facility
priority char(10), # OPTIONAL field for priority
date date, # date of this log message
time time, # time of this message
host varchar(128), # host logging, If you have a host with
# 128 characters you probably
# have other issues to worry about than
#someone being l33t. 8-)
message text,
INDEX host_index (host),
INDEX date_index (date),
INDEX message_index (message (50)) , #Index the first 50 characters
seq int unsigned auto_increment primary key # optional sequencenumber
);
And here is the query
SELECT host, date, time, message FROM syslogTB WHERE host = '$host' AND
date LIKE '%$date%' AND message LIKE '%$message%' ORDER BY date
DESC,time DESC LIMIT " . $start . ", " . $numresults . "");
Thanks
Jenn
