Abstract
Statistics for temporary tables are used in optimizing the execution of a database request. A first temporary table is created using data from a data source as the result of performing an operation while executing the request. A subset of the demographics of the data source is saved in a session level memory as the demographics of the first temporary table. The saved demographics are used in optimizing the execution of the portion of the request involving the first temporary table.
