⟩ What Happens If You Are Trying to Access a Schema Not Owned by You?
In general, if you are trying to access an object in schema owned by another database user, you will get a "permission denied" error, unless that you have been granted access permission to that object explicitly. Here is a tutorial example showing you the permission error:
-- Login with "ggl_login"
USE GlobalGuideLineDatabase;
GO
PRINT User_Name();
GO
ggl_User
SELECT COUNT(*) FROM dbo.ggl_random;
GO
Msg 229, Level 14, State 5, Line 1
SELECT permission denied on object 'ggl_random',
database 'GlobalGuideLineDatabase', schema 'dbo'.
