Re: [ADSM-L] Speeding up my SQL query

Richard meant to say to update ur query to:

select -
   actlog.nodename as "Node Name", -
   substr(char(actlog.date_time), 1, 16) as "Date/Time", -
   substr(actlog.message, 26) as "Message" -
from actlog,nodes -
where -
    actlog.nodename=nodes.node_name -
and actlog.msgno in (4005,4007,4018,4037,4987) -
and (actlog.date_time between '%s' and '%s') -
and (nodes.contact like 'Windows%%') -
order by actlog.nodename

Am I right Richard?

Hi Richard!
Thank you very much for your reply!
Since I'm not much of an SQL wizzard, could you please help met with
rebuilding the query?
Kindest regards,

Eric -

One thing you can do is use the SQL clause IN rather than a succession
of OR conditions to improve the query performance of testing for
multiple values.
