Collecting statistics provides the Optimizer with the data demographics it needs to generate good query plans. The more accurate and up-to-date the statistics, the better the Optimizer can decide on plans and choose the fastest way to answer a query. The computed results are stored in the Data Dictionary DBC.StatsTbl for use during the optimizing phase of statement parsing. The Optimizer does not accept pragmas or hints, and bases query plans only on statistics.
