Use the Update Statistics Task dialog to update Microsoft SQL Server information about the data in the tables and indexes. This task resamples the distribution statistics of each index created on user tables in the database. The distribution statistics are used by SQL Server to optimize navigation through tables during the processing of Transact-SQL statements. To build the distribution statistics automatically, SQL Server periodically samples the data in the corresponding table for each index. This size of the sample is based on the number of rows in the table and the frequency of data modification. Use this option to perform an additional sampling using the specified percentage of data in the tables. SQL Server uses this information to create better query plans.
This task executes the UPDATE STATISTICS statement.
