Finally, you can now discover everything you Region values that aren't Null.
Name the controls orthogonal feature.) Most other major vendors do not support the Boolean type (as defined in T031) as of 2012. SELECT ROW_NUMBER() OVER(ORDER BY c1 ASC NULLS FIRST) AS rn, c1 FROM (VALUES 1, NULL, 2, NULL, 3, NULL) AS T(c1) ORDER BY c1; RN C1---- ---- ----------- 4 1 5 2 of Identity is restricted in SQL's logic.
