ABSTRACT:
The present invention provides a system and method for retrieving data from a computerized database system. Prior to execution of a query statement, the system determines an optimal sequential execution plan for the query statement. The optimal sequential execution plan is used to determine an optimal parallel execution plan. During the execution of the query, run time variables are used to determine whether to use the sequential execution plan without modification or a modification of the parallel execution plan.
