I got fed up trying to link to the software directly without returning too many or too few results so opted to join to a sub-select.
First, I suggest you run this:
SELECT Distinct
softwarename
FROM
tblSoftwareUni
WHERE
SoftwarePublisher LIKE 'Microsoft%'
AND softwareName LIKE 'Microsoft Office%'
AND softwareName NOT LIKE '%Viewer%'
AND softwareName NOT LIKE '%Visio %'
AND softwareName NOT LIKE '%Project%'
AND softwareName NOT LIKE '%web comp%'
AND softwareName NOT LIKE '%connector%'
AND softwareName NOT LIKE '%click-to-run%'
AND softwareName NOT LIKE '%validat%'
AND softwareName NOT LIKE '%live meet%'
Microsoft has named
way too many programs and components "Microsoft Office
something-or-other" that aren't actually Microsoft Office. I've included several substrings to search for that are in my inventory. If you turn up anything other than actual Microsoft Office results with the above, you'll want to add to the list of exceptions. You'll need that list for the actual query you're after.
Adding to the "list me the Dells" query:
SELECT Top 1000000
tblAssets.AssetID,
tblAssets.AssetName,
tsysAssetTypes.AssetTypename,
tsysAssetTypes.AssetTypeIcon10 AS icon,
tblAssets.IPAddress,
tblAssets.Lastseen,
tblAssets.Lasttried,
tsysOS.OSname,
CASE
WHEN tblComputersystem.SystemType Like 'X86%' THEN '32-bit'
WHEN tblComputersystem.SystemType Like 'x64%' THEN '64-bit'
ELSE ''
END AS Bitness,
tblAssetCustom.Manufacturer,
tblAssetCustom.Model,
tblAssetCustom.Serialnumber,
msoffice.SoftwarePublisher,
msoffice.softwareName,
msoffice.softwareVersion
FROM
tblAssets
INNER JOIN tblAssetCustom ON tblAssets.AssetID = tblAssetCustom.AssetID
INNER JOIN tsysAssetTypes ON tsysAssetTypes.AssetType = tblAssets.Assettype
INNER JOIN tsysOS ON tblAssets.OScode = tsysOS.OScode
INNER JOIN tblComputersystem ON tblAssets.AssetID = tblComputersystem.AssetID
LEFT JOIN ( SELECT
tblSoftware.AssetID,
tblSoftwareUni.SoftwarePublisher,
tblSoftwareUni.SoftwareName,
tblSoftware.SoftwareVersion
FROM
tblSoftware
INNER JOIN tblSoftwareUni ON tblSoftwareUni.SoftID = tblSoftware.SoftID
WHERE
tblSoftwareUni.SoftwarePublisher LIKE 'Microsoft Corp%'
AND tblSoftwareUni.softwareName LIKE 'Microsoft Office%'
AND tblSoftwareUni.softwareName NOT LIKE '%Viewer%'
AND tblSoftwareUni.softwareName NOT LIKE '%Visio %'
AND tblSoftwareUni.softwareName NOT LIKE '%Project%'
AND tblSoftwareUni.softwareName NOT LIKE '%web comp%'
AND tblSoftwareUni.softwareName NOT LIKE '%connector%'
AND tblSoftwareUni.softwareName NOT LIKE '%click-to-run%'
AND tblSoftwareUni.softwareName NOT LIKE '%validat%'
AND tblSoftwareUni.softwareName NOT LIKE '%live meet%'
) AS msoffice ON msoffice.AssetID = tblAssets.AssetID
WHERE
tblAssetCustom.State = 1
AND tblAssetCustom.Manufacturer LIKE 'Dell%'
(Inclusion of the publisher and version number are optional, of course.)
If you came up with more exceptions that you had to add to the short query above, add your new exceptions to the list in the big query.
