Thought this was straightforward but sadly not
Surprised that the NULL was not caught in the check constraint...
More coffee required.

Note to developers:
CAST(SUBSTRING(CAST(FLOOR(NULLIF(ISNULL(COALESCE(1,NULL),NULL),NULL)) AS CHAR(1)),1,1) AS INT) == 1
So why complicate your code AND MAKE MY JOB HARDER??!Crazy

Thanks for the question. I was pretty sure the check constraint would allow the NULL value.
