Summary
ArcGIS does not permit the deletion of standard coverage fields after importing the data set into a geodatabase feature class. These fields can be removed from the feature class attribute table by turning the visibility off and exporting the new feature class.
Procedure
- Add the geodatabase feature class to ArcMap.
- Right-click the layer in the Table Of Contents.
- Click Properties.
- Click the Fields tab.
- Click a field that you want to remove and uncheck the Visible check box.
- Repeat step 3-5 for all desired fields.
- Click OK.
Warning:
Don't delete the OBJECTID, SHAPE, and SHAPE_Length fields from the Geodatabase. Deleting these fields may compromise the integrity of the geodatabase.
- Right-click the layer name and select Open Attribute Table.
- Make sure all the fields you want in the new attribute table are visible. If not, return to step 1. If they are visible, close the attribute table.
- Right-click the layer name in the Table Of Contents and select Data > Export Data.
- Set the Export dropdown list to All Features within the Export Data dialog box.
- Click the Browse button and navigate to the geodatabase to store the new feature class.
- Name the output feature class and click OK.
You may delete the old feature class.
