How to Create Simple SQL Report based on Registry Entries Scanned

General Task: Needed to add a custom DWORD registry key/value name to all our windows machines with an assigned value (worked)

Next: I created a scan profile that pulls all values from the registry key containing the new value (worked, I can see the custom registry Value Name/Value when I view any individual PC)

Next: I would then like to create a SQL report that lists the machines that have NOT YET received this custom registry key.

How would I go about creating this simple report? Non-Working Example SQL: select RegistryEntries.Name as "Registry Entry Name", from RegistryEntries where RegistryEntries.Name NOT LIKE 'custom Value Name'
