Re: MVS select statement

[Joni Moyer]

Thank you all for your input!

The parentheses worked!  Are there any suggestions on what msgno's I should
be looking for or are more common than others?  This select statement ran
forever and it was suggested that I narrow down my search, but I wasn't
sure what I should/shouldn't be looking for on a daily basis.

Thanks again!

AND has precendence over OR, so your "where" criteria are being evaluated
like this:

   where cond1 OR (cond2 AND cond3)

In your case, "cond1" is for the messages of severity 'E', so those are
displayed regardless of the date.

Put parentheses around the ORed conditions to fix the problem:

   where (cond1 OR cond2) AND cond3

i.e.

   select date_time, msgno, message
      from actlog
      where (severity='E' or severity='W')
      and date_time>(current_timestamp-(1 day))

Hello all!

I have been trying to set up a select statement to look for all of the
error and warning messages within the past 24 hours.  Here is what I have
come up with:

select date_time, msgno, message
   from actlog
   where severity='E' or severity='W'
   and date_time>(current_timestamp-(1 day))

My problem is that it goes through the entire 14 days of the activity log
that I have and ignores the last statement.  Any suggestions?

Thanks in advance!!!
