Abstract

A method, computer program, and database system for performing a request on a table associated with an index are disclosed. A database contains a table, an index, and a partition elimination list and accepts a query. A table has one or more rows stored in one or more partitions. The index contains index entries, each of which references a row in a partition, where the row is in the table. The query has a first and a second condition. The partition elimination list is populated with partitions based on the first condition of the query. Only index entries that are identified by the request because of the second condition and that reference partitions that are not eliminated by the partition elimination list are read.
