Rebuild Index Task (Maintenance Plan)

 

Applies To: SQL Server 2016

Use the Rebuild Index Task dialog to re-create the indexes on the tables in the database with a new fill factor. The fill factor determines the amount of empty space on each page in the index, to accommodate future expansion. As data is added to the table, the free space fills because the fill factor is not maintained. Reorganizing data and index pages can re-establish the free space.

The Rebuild Index Task uses the ALTER INDEX statement. For more info about the options described on this page, see ALTER INDEX (Transact-SQL).

Connection
Select the server connection to use when performing this task.

New
Create a new server connection to use when performing this task. The New Connection dialog box is described below.

Databases
Specify the databases affected by this task.

  • All databases

    Generate a maintenance plan that runs maintenance tasks against all SQL Server databases except tempdb.

  • All system databases

    Generate a maintenance plan that runs maintenance tasks against each of the SQL Server system databases except tempdb. No maintenance tasks are run against user-created databases.

  • All user databases

    Generate a maintenance plan that runs maintenance tasks against all user-created databases. No maintenance tasks are run against the SQL Server system databases.

  • These specific databases

    Generate a maintenance plan that runs maintenance tasks against only those databases that are selected. At least one database in the list must be selected if this option is chosen.

    System_CAPS_ICON_note.jpg Note


    Maintenance plans only run against databases set to compatibility level 80 or higher. Databases set to compatibility level 70 or lower are not displayed.

Object
Limit the Selection grid to display tables, views, or both.

Selection
Specify the tables or indexes affected by this task. Not available when Tables and Views is selected in the Object box.

Default free space per page
Drop the indexes on the tables in the database and re-create them with the fill factor that was specified when the indexes were created.

Change free space per page to
Drop the indexes on the tables in the database and re-create them with a new, automatically calculated fill factor, thereby reserving the specified amount of free space on the index pages. The higher the percentage, the more free space is reserved on the index pages, and the larger the index grows. Valid values are from 0 through 100.

Sort results in tempdb
Use the SORT_IN_TEMPDB option, which determines where the intermediate sort results, generated during index creation, are temporarily stored. If a sort operation is not required, or if the sort can be performed in memory, the SORT_IN_TEMPDBoption is ignored.

Pad index
Specify index padding

Keep index online
Use the ONLINE option which allows users to access the underlying table or clustered index data and any associated nonclustered indexes during index operations.
