The Code Block parameter allows you to create complex expressions. To use the random module successfully, add it as an import in the Code Block parameter. Comparable functions using Python's random module should be used instead. To calculate a field to be a numeric value, enter the numeric value in the Expression parameter no quotation marks around the value are required.Īrcgis.rand() is no longer supported as of ArcGIS Pro 2.0. To calculate strings to text or character fields, on the dialog box, the string must use double quotation marks ("string"), or in scripting, the string using double quotation marks must also be encapsulated in single quotation marks ('"string"'). Make a copy of the input table if you want to preserve the original values.įor Python calculations, field names must be enclosed in exclamation points (!fieldname!).įor Arcade calculations, field names must be prefixed with $feature.
To apply multiple calculations, use the Calculate Fields tool.Įxisting field values will be overwritten. The calculation can only be applied to one field per operation.
CALCULATE GEOMETRY X ARCPY UPDATE
When used with a selected set of features, such as those created from a query in Make Feature Layer or Select Layer By Attribute, this tool will only update the selected records. To learn more about SQL expressions, see Calculate field values. To learn more about Arcade expressions, see the ArcGIS Arcade guide. To learn more about Python expressions, see Calculate Field Python examples.
