Deleting fields

You can delete fields from your table using ArcCatalog or ArcMap. In ArcCatalog, you need to open the layer or table's Properties dialog box and delete the field from the list on the Fields tab. In ArcMap, you can delete a field through the Catalog window by accessing the same Properties dialog box and Fields tab or through the attribute table of a layer. Inside either application you can also use the Delete Field tool.


You cannot delete a field from a table that is stored in an ArcSDE geodatabase for DB2 on the IBM z operating system (z/OS). Be aware that deleting fields in DB2 LUW 9 or later databases may take a long time depending on the size of the table.

  1. Right-click the table or layer in the table of contents and choose Open Attribute Table.
  2. Right-click the field header in the table window of the field you want to delete and click Delete Field.
  3. Click Yes to confirm the deletion.

    Deleting a field cannot be undone.


The Add Field and Delete Field options are unavailable when you're editing the table.
