Add value to entire column in attributes

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.

This is what happends when i use field calculator.

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

Answer 1

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

[ONEWAY] = "B"

• obviously our fields are a little different, just make sure you select the field you want to calcuate to

Answer 2

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

Answer 3

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.
