An overview of the Fields toolset

The Fields toolset contains a set of tools to add and make changes to the fields in the tables of a feature class. 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. Settings can be specified for fields, such as the field type and the maximum size of the data that can be stored in it.

Assign Default To Field

This tool will create a default value for a specified field. Whenever a new row is added to the table or feature class, the specified field will be set to this default value.

Calculate Field
