  • Generating Materialized Query Table Candidates
    Publication number: 20110196857
    Abstract: Techniques for generating a set of one or more materialized query table (MQT) candidates for a workload are provided. The techniques include receiving a workload, wherein the workload comprises a set of one or more queries, generating one or more best matching MQTs (BMQTs) based on one or more query blocks of the one or more queries by removing syntax that is not qualified for a MQT re-write, determining one or more frequently used multi-joins in the workload, using the one or more BMQTs and the one or more frequently used multi-joins to generate a set of one or more workload MQTs (WMQTs), and grouping one or more WMQTs and one or more BMQTs into one or more groups to merge into a set of a smaller number of MQTs and to cover the workload.
