The question was what should replace xxx in " SELECT 'xxx', ... ".
There are already quotes around the xxx. Why would I include another set of quotes around the SQLCMD...

I usually customize SSMS by defining a hotkey for this, like Ctrl-F7.

But if you must use explicit line breaks, a single line feed...

If your original query didn't work, you probable have to worry about NULLs.
An EXCEPT query is simpler to write and will deal with NULLs correctly, but performance depends on rowcounts...
