I use a python script to compare the value of a field like follows: def compare(class1): if class1 in (612, 611): return "Text1" elif class1 == 617: return "Text2" else: return !Field! (followed by arcpy.CalculateField_management...) this works per...
The calculation can only be applied to one field per operation. To apply multiple calculations, use theCalculate Fieldstool. Existing field values will be overwritten. To preserve the original values, make a copy of the input table as a backup, or use theEnable Undooption in theGeoprocessingpan...
