Alter Domain (Data Management Tools)

Summary

Alters the properties of an existing attribute domain in a workspace.

Usage

  • Domain management involves the following steps:

    1. Modify an existing domain using this tool, or create a new domain using the Create Domain tool.

    2. Add values to or set the range of values for the domain using the Add Coded Value to Domain tool or Set Value For Range Domain tool.

    3. Associate the domain with a feature class using the Assign Domain To Field tool.

  • Coded value domains only support the default value, duplicate split policy, and default value merge policy.

  • Range domains support all split and merge policies. After a split or merge operation, the attribute values of output features are calculated based on the numeric values of the input features and the specified split or merge policy.

  • The properties of a domain in an enterprise geodatabase workspace can be altered when the Input Workspace value is a database connection file connected as the domain owner or the geodatabase administrator.

Parameters

Label Explanation Data type

Input Workspace

The geodatabase that contains the domain that will be altered.

Workspace

Domain Name

The name of the domain that will be altered.

String

New Domain Name

(Optional)

The new name of the domain.

String

New Domain Description

(Optional)

The new description of the domain.

String

New Split Policy

(Optional)

Specifies the split policy that will used for the domain. The behavior of an attribute's values when a feature is split is controlled by its split policy.

  • Use the attribute's default value—The attributes of the two resulting features will be the default value of the attribute of the given feature class or subtype.

  • Duplicate attribute values—The attribute of the two resulting features will be a copy of the original object's attribute value.

  • Use geometric ratio—The attributes of resulting features will be a ratio of the original feature's value. The ratio is based on the proportion into which the original geometry is divided. If the geometry is divided equally, the attribute of each new feature will be one-half the value of the original object's attribute. This option only applies to range domains.

String

New Merge Policy

(Optional)

Specifies the merge policy that will be used for the domain. When two features are merged into a single feature, merge policies will control attribute values in the new feature. This parameter is only applicable to range domains, as coded value domains can only use the default merge policy.

  • Use the attribute's default value—The attribute of the resulting feature will be the default value of the attribute of the given feature class or subtype. This option only applies to nonnumeric fields and coded value domains.

  • Sum of the values—The attribute of the resulting feature will be on the sum of the values from the original feature's attribute. This option only applies to range domains.

  • Area weighted average—The attribute of the resulting feature will be the weighted average of the attribute values of the original features. The average is based on the original feature's geometry. This option only applies to range domains.

String

New Domain Owner

(Optional)

The name of the database user that the domain ownership will be transferred to. Ensure that the new domain owner exists in the database; the tool does not check the validity of the owner name specified. This parameter is not applicable for domains created in a file geodatabase.

String
