unfortunately CTE is not allowed in this particular staging table creation, and even if it is allowed, 10 million records would be a lengthy dump.:crazy:
So use a temp table.
Using that case statement (or a udf) in the group by is a recipe for causing your query to perform terribly.
Dumping to a temp table will often solve that.
