An overview of the Fields toolset

The Fields toolset contains tools for creating, modifying, and deleting fields. A field is a column in a table; each field contains the values for a single attribute. Any number of fields can be included in a table. Field settings can be specified, such as the field type and the maximum size of the data that can be stored in it.

Tools in the Fields toolset

Tool	Description
Add Field	Adds a new field to a table or the table of a feature class or feature layer, as well as to rasters with attribute tables.
Add Fields (multiple)	Adds new fields to a table, feature class, or raster.
Alter Field	This tool allows you to rename fields or field aliases for a geodatabase table or feature class.
Alter Fields	Alters the field properties of multiple fields in a feature class or table.
Assign Default To Field	Creates a default value for a specified field. When a new row is added to the table or feature class, the specified field will be set to this default value.
Batch Update Fields	Transforms fields in a table or feature class based on schema defined in the definition table and creates a new table or feature class.
Calculate Field	Calculates the values of a field for a feature class, feature layer, or raster.
Calculate Fields (multiple)	Calculates the values of two or more fields for a feature class, feature layer, or raster.
Delete Field	Deletes one or more fields from a table, feature class, feature layer, or raster dataset.
Migrate Text Field	Migrates text fields in an Oracle table from Unicode to non-Unicode types.

The Fields toolset also includes additional toolsets for working with fields.

Toolsets in the Fields toolset

Toolset	Description
COGO	The COGO toolset contains tools for enabling and disabling COGO on a line feature class.
Data Engineering	The Data Engineering toolset contains tools for preparing fields for analysis workflows, such as transforming, standardizing, encoding, and reclassifying values. These tools are designed to ensure that datasets are clean, consistent, and ready for modeling or analysis workflows.
Database	The Database toolset contains tools for adding global ID and incrementing ID fields, and for managing editor tracking.
Date and Time	The Date and Time toolset contains tools for temporal field manipulation.
GPS	The GPS toolset contains a tool for adding GNSS fields to a feature class.
