How to: Delete Indexes
Indexes can slow INSERT, UPDATE, and DELETE performance. If you find that an index hinders overall performance or you no longer need it, you can delete it.
Note
Your computer might show different names or locations for some of the Visual Studio user interface elements in the following instructions. The Visual Studio edition that you have and the settings that you use determine these elements. For more information, see Visual Studio Settings.
To delete an index
In Server Explorer, select the database table with indexes you want to delete.
From the Database menu, click Open Table Definition.
From the Table Designer menu, click Indexes/Keys.
In the Indexes/Keys dialog box, select the index you want to delete.
Click Delete.
The index is deleted from the database when you save your table.
Note
If you delete an index in Table Designer but you do not want to delete it from the database you can close the table without saving changes. This will also discard all other changes made since the table was last saved.
