4. Right-click the icon of the physical operator that suggests that statistics need to be created (table name in red), and then click Create Missing Statistics.... The database, table, and column(s) that the Graphical Execution Plan suggests need new statistics are automatically selected.
5. Optionally, in Statistics name, enter the name for the statistics.
6. Optionally, in Amount of data to sample, select:
   • Default to let Microsoft® SQL Server™ determine the number of rows to sample automatically.
   • Sample all the data to instruct SQL Server to sample all of the data in the table.
   • Sample % of the data and enter a percentage of data to sample to base the statistics on.
7. Optionally, select Do not automatically recompute statistics (not recommended) to prevent SQL Server from updating statistics automatically as the data is updated.
8. Optionally, click Edit SQL... to view and edit the Transact-SQL statement used to create or update the statistics.
