Better way to write a WHERE clause with multiple <> conditions from same object

Question

I have built a statement to return the sizes for an component attached to the order. The issue i have is the query returns all components on the order such as delivery and packing which are irrelevant to me. All together there is over 45 components that i am not interested in seeing. To exclude these i have put into there WHERE clause everything i don't want to see. My problem is i feel this isn't the best way for me to approach with multiple AND 's listing each and every one.

To save the hassle i have put the main query below and only a portion of the where clause

SELECT

Job_0.JobJobNumber AS 'Job Number'
,Job_0.JobEstimateNumber AS 'Estimate Number'
,Component_0.CooComponentDescription AS 'Component'
,Component_0.CooMfsDescription AS 'Finished Size'
,Component_0.CooDownSize AS 'Down Size'
,Component_0.CooAcrossSize AS 'Across Size'
,Component_0.CooDownFactor AS 'Down Gap'
,Component_0.CooAcrossFactor AS 'Across Gap'
,MasterWorkingSize_0.MwsDescription AS 'Working Size'
,MasterWorkingSize_0.MwsMinimumWidth AS 'Width'
,MasterWorkingSize_0.MwsMinimumLength AS 'Length'

FROM
SBS.PUB.Job Job_0
JOIN SBS.PUB.Component Component_0 ON Job_0.JobID = Component_0.JobID
JOIN SBS.PUB.WorkingSize Workingsize_0 ON Job_0.JobID = WorkingSize_0.JobID
JOIN SBS.PUB.MasterWorkingSize MasterWorkingSize_0 ON WorkingSize_0.MasterworkingsizeID = MasterWorkingSize_0.MasterworkingsizeID

WHERE

Job_0.JobID > 254677392
AND Component_0.CooComponentDescription <> 'Packing'
AND Component_0.CooComponentDescription <> 'Delivery'
AND Component_0.CooComponentDescription <> Packing in 1,000s
AND Component_0.CooComponentDescription <> Finish Pad of Sets
AND Component_0.CooComponentDescription <> Part Outsourced
AND Component_0.CooComponentDescription <> Finishing Booklets
AND Component_0.CooComponentDescription <> Packing - band in 50s
AND Component_0.CooComponentDescription <> Small Job Uplift £10
AND Component_0.CooComponentDescription <> Packing band in 50s

I was wondering other than what i have done above is there a better way in which i could nest these? Much like you can do in a CASE WHEN statement. what i hope to see is something like AND Component_0.CooComponentDescription <>('Packing', 'Delivery', Packing in 1,000s,etc,etc)

Answer 1

您似乎不想not in ：

Component_0.CooComponentDescription not in ('Packing', 'Delivery', 'Packing in 1,000s', etc, etc)

Answer 2

The method I would use would be to create a new table with a column that lists your exclusions, then use:

    SELECT columns
       FROM SBS.PUB.Job Job_0
       JOIN SBS.PUB.Component Component_0 ON Job_0.JobID = Component_0.JobID
       LEFT JOIN ExcludeComponent exc ON exc.CooComponentDescription = Component_0.CooComponentDescription
       WHERE exc.CooComponentDescription IS NULL

Then just populate ExcludeComponent.CooComponentDescription1 with your list of 45 items. The advantage here is that this is more dynamic than putting all the terms in your query.
