Field Python Class

重要

This Python SDK uses outdated technology that limits your extension opportunities.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.数据类型
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.
