SELECT default_schema_name FROM
sys.database_principals
WHERE name = (SELECT user_name())
AND type = 'S'
for some reason on your system it's coming up as MyDatabase. You'd want to

This might be because the tables you're trying to reference are themselves not

help confirm this, as well as the same CREATE TABLE statement below.
