Field Python Class

Important

This Python SDK uses outdated technology that limits your extension opportunities. We've built a new Platform SDK using Python and the latest open-source technology to deliver a vastly improved development experience. Go to Platform SDK to get started!

The Field class is provided as a reference class to extend the class members of a Field object instantiated within the running Alteryx process. Use the methods in the Field class to impact field types and metadata.

Field Types

This is a list of the field types recognized by the Alteryx Engine:

binary	boolean
numeric	byte, int16, int32, int64, fixeddecimal, float, double fixeddecimal requires both size and scale. See Data Types for more information about fixed decimal in Alteryx.Data Types
string	string, wstring, v string, v_wstring
date/time	date, time, datetime The format for these types is YYYY-MM-DD HH:mm:SS.
spatial	spatial object
blob	blob

Read-Only Field Attributes

description: The description of the field.

max_bytes: The maximum number of bytes a variable-length field can hold.

name: The name of the field.

offset: The offset of the field.

position: The 0-based index of the field in its parent RecordInfo.

scale: The scale of the field.

size: The size of the field in bytes.

source: The source of the field.

type: The type of the field.
