By the way, we are using a correlated sub query in this case. So what about a scenario where the lookup table is not key preserved?

The following code example creates and explicitly sets properties to update a two-table view.

You can use this example as a guide for customizing update property settings on a view.

Additional points: There are nine primary labels and each of the nine have multiple details (a company can have all nine primaries and all detail labels).

I would then run queries off of the company table to find companies with the primary and/or detail project label I am currently looking for.
