Guys and gals could you please provide me with a sample code as to how to rename a field name in a Feature Layer or Table. I've been trying to use the FieldInfo object to do so over the last couple of days but it's not happening for me.
What this example code does is to add two NEW fields ("NAME_CITY"; "NAME_REGION") into your fieldinfo with desired new field names instead of just renaming the ORIGINAL field ("NAME_1"; "RegionNames").
After you renamed your fields you need to copy your table view/feature layer into a new table/feature class and that will be your output with renamed fields in it.
Sorry for the delay. I just modified the python script and it is now using the "setNewName" method to rename a existing field instead of adding a new field.
I think this is what you are looking for.
Please let me know if you have any questions regarding the code above.
