In my attribute table, I have over 200 fields and tens of thousands of rows or attributes. I am trying to sum the values in each field across each row. This seems like a basic function but when I search for this topic, I've only found instructions on summing entire fields. I could just select each individual field with a "+" in between in the field calculator but there has to be a simpler way than that.
In the field calculator there isn't a simpler way as far as I know. I do not think that it is common to want to sum every field in a row without being selective of the fields to be summed. Python could be used in the field calculator to do this, but you would end up writing code that is better to run in a script.
