I am using ArcMap 10 from ArcGIS 10.2.1 package.
I got an attribute table, with few collumns. I need to replace some column "String_A" entries with newer "String_B" entries, in the same row. In both "String_A" and "String_B" columns are some values. Some entries in column "String_A" dont need to be changed, only those, where "String_B" entries not . Both columns are strings.
I am doing it by hand for now, but it would be nice to have a script in python, that can do it for me, because from time to time I need to update table with some new entries.
I am learning python, but with my knowledge for today I can't do this task. So, I need some help with Field calculator and python :)
From "String_B" to "String_A" replace entries, example in the picture: http://tinypic.com/r/2dcd79u/8
