Need to optimize query...

  • Thread starter Thread starter madforplaid
  • Start date Start date
I have the following table and query (image URL follows) that
accomplishes what I need it to, i.e. return all records but the
preselected ones:  http://www.dslextreme.com/users/madforplaid/Inovant_Table_and_Query.jpg

However, with larger data sets how can I rewrite it in a simpler
manner to optimize the query further?  I have already tried NOT IN and
NOT EXISTS to no avail.

Thanks much,

Paul

It's possible that the concatenation of [Account],
,
[Activity] and [Cost SUM], using all those intervening hyphens, is
slowing the result sets return.

Try:

SELECT FA_Inovant2.*
from FA_Inovant2
where FA_Inovant2.[Cost SUM] is not null
and not exists
( SELECT 'true'
FROM FA_Inovant2
WHERE [Account] = '731300'
and
= '88107'
and [Activity] = '804392'
and [Cost SUM] = '1430500' )​

Lou,

My concatenation method does work, but after trying your SQL it
returns no records as a similarly written NOT EXISTS query had done
for me.

Any other ideas?

Perhaps this is what you are looking for.

SELECT F.*
FROM FA_Inovant2
WHERE [Cost Sum] is not null
AND Not(Accounts = "731300"
AND Center = "88107"
AND Activity = "804392"
AND [Cost Sum] = 1430500 )

John,

That worked perfectly (once I adjusted the alias table name 'F');
thanks so very much!

Paul
