I have a feature class in a file geodatabase that was created through a join, and ended up with 2 shape length fields. The extra one was renamed Shape_Length_1 and all values are null; however, I'm not able to delete or modify it. Is there any way to get around this? I understand I can't delete the primary Shape_Length field, but I would like to have a way to get rid of the extra, blank, field. The Delete Field tool does not give me the option to delete this field at all.
Is your join temporary?
You should be able to delete the unwanted field using the latter. Better still, specify the fields your want instead using Join Field
Hi Dan, I had previously joined data, and then exported to a new FC. I had created new feature classes using the Dissolve tool, to merge features with the same ID, and then joined the original data back to it on that ID field. When I did the join and then exported to a brand new FC, I didn't specify for it to join the old shape length field, but it did it anyway (as Shape_Length_1) and all were listed as Null.
Long history for the data. Have you tried
you can delete fields, and/or change their properties. Perhaps a combination of those will allow you to get rid of the field.
