You day it is erroring, what is the error?

Also try printing you dynamic SQL before you run it so you can verify it is what you expect.

Why would it? Your dynamic SQL starts with a select, so the quiet getting executed is a select. You would want something more along the lines of

Select...

I think I misrepresented the "Database Owner" role and the database "owner". "Database Owner" is a role. The database "owner" is the person who created the database. Multiple people can...

As a guess, I imagine a few joins could help and no loop would be required.

BUT It depends on how you designed things. Is that 4 tables? If so, I...

It depends. Is your powershell script calling a SQL script to handle the backups or are you using a 3rd party backup solution or powershell itself for the backups.

I am 99.9999999999% sure that the problem is not on the SQL side - that is an application bug. SQL takes a query and provides results. There is literally no...

My opinion - that's pointless. Statistics tell you information about your table data. If the table is empty, the statistics are (mostly) useless. You need data in the table for...
