No, SQL Server doesn't let you pass tables or columns as parameters. You could derive something like this using dynamic SQL.
But I might also we concerned about protentional blocking when...

You have no indexes, so you are forcing the query engine to scan the entire tables.
Yes, not equals/not in/not exists can be less efficient than equals/in/exists, but with proper indexing...

One True Lookup Table:
In addition to other concerns, to me, I tend to view lookup tables themselves as an entity. If they contain unrelated "things", they are not normalized. And...

You would have to use a user-defined function to reference columns in other tables (which could have performance impacts).
Your table design may be wrong if you have a column value...

Hosts file alias?
SQL Native client alias?
CNAME or AD computer name alias?

What percent_complete does the progress query return? (know that it's not necessarily linear/precise)
What reasons do you have to believe restore will suddenly become faster and complete in a small fraction...

Note: SQL Server Express is not supported as a replication publisher - only as a subscriber.
So backup & restore or a homebuilt process for pulling data to the central...

Another option would be to restore backups...

Employee/Person: Response By indicates a relationship in another table to Employee/Person. It is not an attribute of Employee/Person. Even less so is Response On datetime. Attributes of an Employee/Person might...

Good point. I got tangled in the jumping between tables and logical design too.
My intent (not clearly stated) was for table naming.

Glad to hear it!
First rule of tech support. 🙂

That's an ELT (Extract, Load, & Transform) strategy using a staging table, as opposed to an ETL strategy (in which you would do the transformation before importing, loading directly into...

As Scott already suggested, think about entities & attributes.
What are the entities (actors/objects/categories) involved? What attributes do the entities have? How do they relate? One-to-one? Many-to-many? (e.g., can you have...

CPZ Name & CPZ Code appear to be related. Is it one-to-one? (in which case they should be in a lookup table, and only reference CPZ Code in other tables)
Or...

That conversion is going to be fun in SQL 2012. /s
In addition to the usual fun in converting among timezones in the United States, you have the additional complexity that...
