Define SQL Server Index Storage Properties

Use the Options tab in the SQL Server Table Index Editor to specify physical storage properties at the index level for the selected index for a SQL Server physical model.

To define SQL Server index properties

  1. Right-click a table index in the Model Explorer and click Properties.

    The SQL Server Table Index Editor opens.

  2. Select the table from the Table drop-down that contains the index that you want to define.
  3. Select the index in the Navigation Grid that you want to define.

    Note: Click New New icon in property editors to create a new object on the toolbar to create a new index. Use the Enter filter text box to filter a very large list of indexes to quickly locate the one that you want to define.

  4. Work with the following options:
    Table

    Displays the table to which the selected table index belongs.

    property editor PREVIOUS icon Previous

    Positions the editor on the previous table index in the Navigation Grid.

    property editor NEXT icon Next

    Positions the editor on the next table index in the Navigation Grid.

    Table Index Editor Toolbar_Index Sort Order Button Sort

    Sorts the table indexes by alphabetic, reverse alphabetic, or index order. You select the method you want using the drop-down menu that opens after you click the Sort button.

    New icon in property editors to create a new object New

    Creates a new table index that becomes the current object in the editor.

    property editor DELETE button Delete

    Deletes the selected table index.

    property editor HELP button Help

    Accesses online help for the editor.

    enter filter text box in a property editor to filter object list

    Lets you enter text to filter a large list of table index objects so you can quickly locate the one that you want.

    Show FK Indexes

    Specifies to display FK (foreign key) indexes in the Navigation Grid.

    Physical Name

    Displays the physical name of the table index.

    Type

    Displays the table index type.

    Is Unique

    Specifies to allow only unique values in the table index. Clear this check box to allow non-unique values.

    Note: This option is unavailable when a primary or foreign key index is selected.

    Physical Only

    Specifies whether to have the index appear in the physical model only. If you want the index to appear in the logical model as a key group, clear the check box.

    Note: This option is unavailable when a primary or foreign key index is selected.

    Generate

    Generates SQL during forward engineering. Clear the check box if you do not want to generate SQL.

  5. Click the Options tab and work with the following options:
    Fill Factor

    Lets you enter the percentage to use to indicate how full SQL Server should make each index page during index creation.

    Pad Index

    Lets you specify the space to leave open on each node in the intermediate levels of the index.

    Note: If you use the PAD_INDEX option, make sure you enter a percentage in the FILLFACTOR field. PAD_INDEX uses the percentage specified in the FILLFACTOR field.

    Sort In Temp DB

    Specifies whether to store sort results in tempdb. The default is OFF.

    No Recompute

    Lets you specify that outdated index statistics are not automatically recomputed.

    Statistics Incremental

    Specifies whether the statistics created are per partition statistics. The default is False.

    Online

    Specifies whether underlying tables and associated indexes are available for queries and data modification during the index operation. The default is False. REBUILD can be performed as an ONLINE operation.

    Max Wait Duration

    Specifies the wait time (an integer value specified in minutes) that the SWITCH or online index rebuild lock (that must be acquired) will wait when executing the DDL command. Enabled only if the Online option is set to True. Available SQL Server 2016 onward.

    Abort After Wait

    Specifies the action to be executed if the operation is blocked for the Max Wait Duration time. Enabled only if the Online option is set to True. Available SQL Server 2016 onward.

    Filegroup

    Lets you select a filegroup in which the table that contains the selected index should be stored. Click the Filegroups Editor Icon in SQL Partition Scheme Editor button to open the SQL Server File Group Editor to create or modify filegroups.

    Filestream Partition Scheme

    Specifies the partition scheme to be used to store filestream data for a partitioned index. Select a partition scheme from the drop-down list or click New New icon in property editors to create a new object to create one.

    Filestream Filegroup
