Abstract
A technique and mechanism for transforming a query is described. A given query is transformed into a transformed query that references a global temporary table. Specifically, the given query contains a join between a given table and one or more other tables referenced by constraints (e.g. predicates). References to one or more of the constrained tables are replaced by a reference to a global temporary table. Before executing the transformed query, data that satisfies the constraints placed on the constrained table is inserted into the global temporary table.
