My problem is that the code is adding numbers to the field names, and this is incorrect.

Problem:

Field should be names VALUE_122, but after running JoinField code, it becomes VALUES_122_123. The values inside are correct.

I have manually gone over the code for the join field, and it does not contain the numbers 123 anywhere.Interestingly, VALUE_123 is not a field in anyone of the 2 tables involved in the joining.

I am using ArcMap 10.1

    It's probably because you have two fields named VALUE_122. – Paul Sep 16 '15 at 0:21
  • Just wanted to make sure it's not a problem of having qualified field names enabled e.g. TableName1.FieldName1. I suspect @Paul is right, Both tables have a field called VALUE_122, so when you join them, one field gets renamed something else. Field names are validated internally each time a new field is added in the user interface. – John Sep 16 '15 at 12:01
  • I agree with Paul. To elaborate, you likely have VALUE_122 in the target and source layers of your join. I have seen this many times. – jbchurchill Sep 16 '15 at 16:50

The problem is that the field in question appears in both the tables. Possible fix is to copy one of the fields, re-name and then delete original field. Can confirm that I was unable to find the setting for the Qualified Field Names, and it did nothing in the script.

    In the menu Geoprocessing > Environment Settings > Fields is a checkbox to maintain fully qualified field names. This can also be accessed in python via arcpy.env.qualifiedFieldNames = True. – recurvata Sep 16 '15 at 19:30
