Index Properties


Use this form to add or edit indexes and unique constraints attached to your database tables.

Access this form by selecting the Tables node (within a database) on the navigation pane, then select the required table in the object list and click the manage indexes icon .

Name
Shows the name of the index.

Type
Shows the index or key object type for the selected table: index, primary key, or unique.

File group
Select the name of the file group in which you want to store the selected index. If you create a database object and do not specify its file group, SQL Server will assign it to the default file group. Initially, the default file group is the Primary file group.

Fill factor
Shows the fill factor that specifies how full each index page can be. If a fill factor is not specified, the database's default fill factor is used.

Pad Index
If you specified a Fill Factor of more than zero percent, and you selected the option to create a unique index, you can tell SQL Server to use the same percentage you specified in Fill Factor as the space to leave open on each interior node. By default, SQL Server sets a two-row index size.

Columns
Shows the columns contributing to the index, primary key, or unique constraint, along with whether each column's values are arranged in ascending or descending order within the item. You can add, change, or remove column names in this list. You can also change the ascending/descending setting for each column.

Create UNIQUE
Select this option to create a unique constraint or index for the selected database table. Specify whether you are creating a constraint or index by selecting either the Constraint or Index option.

Ignore duplicate key
If you create a unique index, you can set this option to ensure each value in an indexed column is unique.

Create as CLUSTERED
Select this option to create a clustered index for the selected database table.

Do not automatically re-compute statistics
Select this option to tell SQL Server to use previously created statistics. This choice may not produce optimal results and is not recommended.
