¿Cómo hacer un giro incómodo de la tabla sql en SQL Server 2005?

Esto debería solucionarlo. Es realmente un UNPIVOT y un PIVOT. Tenga en cuenta que debe ajustar sus datos porque UNPIVOT coloca todos los datos en la misma columna.

Tenga en cuenta que tuve que volver a crear/rellenar la variable de la tabla en el SQL dinámico interno; por lo general, esto no es necesario cuando se trata de una tabla permanente.
