I created a report that shows effiency for each associate (K.AID). I
am trying to figure out how to use GROUP BY to AVG(Effiency) for each
K.AID in subquery. Originally I used temporary tables (4) to figure
out the average effiency for each K.AID. That often left hanging
temporary tables and took long time to process information. And I also
need to sum(dhours) on hours worked for each category and to subtract
that from K.hours (clocked in hours) which shows the idle time for
each K.AID. I already RTFM and STFW trying to figure out how to use
GROUP BY to no avail. Here is the detailed information and example of
my current database that I am working on. Any helpful insights or
suggestions would be of a big help and appreciated..
Thanks,
Scott
