Is there a way to add a value to the entire column? I don't think i can use raster calculator because it's a text i want to add, the letter "B".

Here is a picture.

Attribute table

This is what happends when i use field calculator.


I forgot the """""""". That's why it didn't work.


Just use the field calculator, goto attribute table and right click on the table header, and choose field calculator

[ONEWAY] = "B"

enter image description here

  • obviously our fields are a little different, just make sure you select the field you want to calcuate to
  • I have tried this but it doesn't work. "The calculated value is invalid for the row ObjectID = 0............."

  • try using a single quote 'B' instead of a double quote

Right click on the field name at the top and select "Field Calculator ..." Then in the window type "B" and calculate.


You want to right click the column header and in the pop-up menu that appears, choose the 'Field Calculator' option. Then in the Field Calculator wizard just Type a capitol B in the box at the bottom. Then hit OK and it should add B to every record in that attribute.
