After you create a join, you can change the settings you specified when you created it. You can remove one (of multiple) joins from a feature layer, or remove all joins from the feature layer at once, restoring the properties for that layer to its native data only.
To modify a join
- In Display Manager, right-click the feature layer with the join to modify, and select Manage Joins.
- In the Manage Layer Data dialog box, select the join to modify, and click Edit.
- In the Edit A Join dialog box, change any settings.
The settings are the same ones you used when you created the join. For example, you can change this join from One-To-Many to One-To-One to get rid of extra features created by the original join.
- To delete one (or multiple) joins for this feature layer, click the join to delete (use Ctrl or Shift to select multiple joins). Click Delete.
- When you are finished, click OK.
