I decided there was no way to CREATE a table AS SELECT FROM because there were multiple queries. So I determined the list of columns, and manually created the table with code. The create statement was so huge that I had to break the table creation down into one CREATE TABLE and multiple ALTER TABLE dynamic statements.
It was quite a chore to handle all the cases where a row in the resultant big table was sparse.
