Ok, have a report almost done. It finds all of the information I want but just need to filter a result.
SELECT TOP 100 PERCENT
tblComputers.Computername,
tblComputers.Username,
tblRegistry.Value,
tblSoftware.softwareName,
tblRegistry.Regkey
FROM
tblComputers
INNER JOIN tblRegistry ON (tblComputers.Computername = tblRegistry.Computername)
INNER JOIN tblSoftware ON (tblRegistry.Computername = tblSoftware.ComputerName)
WHERE
tblSoftware.softwareName = 'Catalyst WMS Client' AND
tblRegistry.Regkey = 'HKEY_LOCAL_MACHINE\SOFTWARE\WMS\WMS 011310' AND
tblRegistry.Value IS NOT NULL
Pretty much I displau tblRegistry.RegKey, but I would like to cut off the earlier sections and display only WMS 011310. Is there a way to do that or will I need to add another registry key?
