Abstract
Disclosed is a method, system, and program for database query execution. A range of data pages is assigned to each of multiple parallel tasks. For each of the multiple parallel tasks, the range of data pages is mapped to one or more physical partitions, and a data partitioned secondary index partition associated with each of the one or more physical partitions is identified. Each of the multiple parallel tasks is executed to process the database query against the assigned range of data pages using the one or more data partitioned secondary index partitions.
