Summary

Extracts a subset of data from one geodatabase to another geodatabase or an .xml file.

Learn more about extracting data from a geodatabase

Usage

  • This tool provides similar functionality to copying data from one geodatabase to another but supports copying a subset of data by setting the Extent environment, specifying a Extract Using Geometry Features parameter value, or using a selection. You can also extract the schema and data or schema only.

  • This tool can also be used to extract the schema only for a specified spatial reference by using the Output Coordinate System environment. Once the schema is obtained in the desired spatial reference, you can use the Reuse Schema parameter's Reuse option to extract the data to the new schema. The Output Coordinate System environment is ignored when the data extract type is used.

Parameters

LabelExplanationData Type
Datasets to Extract

The data that will be extracted.

Table View; Dataset
Extract
(Optional)

Specifies whether the schema and rows of the data or only the schema will be extracted.

  • Data—The schema and rows will be extracted. This is the default.
  • Schema only—Only the schema will be extracted.
String
Output Type
(Optional)

Specifies the output type the data will be extracted to.

  • Geodatabase—The data will be extracted to an existing geodatabase. This is the default.
  • XML file—The data will be extracted to an XML workspace document.
  • New file geodatabase—The data will be extracted to a new file geodatabase. Specify the location and name of the new file geodatabase using the Geodatabase Location and Geodatabase Name parameters.
String
Geodatabase to Extract Data to
(Optional)

The geodatabase that will contain the extracted data when the Output Type parameter is set to Geodatabase.

Workspace
XML File to Extract Data to
(Optional)

The name and location of the .xml file that will be created when the Output Type parameter is set to XML file.

Folder
Geodatabase Name
(Optional)

The name of the file geodatabase that will be created for the extracted data. This parameter is required when the Output Type parameter is set to New file geodatabase.

String
Expand Feature Classes and Tables
(Optional)

Specifies whether expanded feature classes and tables—such as those in networks, topologies, or relationship classes—will be added.

  • Use defaults—The expanded feature classes and tables related to the feature classes and tables in the input datasets will be added. The default for feature classes is to extract all features intersecting the spatial filter. If no spatial filter has been provided, all features will be included. The default for tables is to extract the schema only. This is the default.
  • Add with schema only—Only the schema for the expanded feature classes and tables will be added.

  • Do not reuse—The schema will not be reused. This is the default.
  • Reuse—The schema will be reused.
String
Extract Related Data
(Optional)

Specifies whether rows related to rows existing in the data will be extracted. For example, a feature (f1) is inside the geometry filter and a related feature (f2) from another class is outside the filter. Feature f2 will be included in the extracted data if you choose to get related data.

The spatial relationship is applied to data in an extent defined by the area of interest (AOI) specified in the Extract Using Geometry Features parameter.

  • Intersects—Features in the Input Datasets parameter value that intersect features in the Extract Using Geometry Features parameter value will be extracted.
  • Contains—Features in the Input Datasets parameter value that are contained by the selected feature in the Extract Using Geometry Features parameter value will be extracted.
String
All records for tables
(Optional)

Specifies whether all records or only the schema will be extracted for tables that do not have filters applied (such as selections or definition queries).

Tables with applied filters will be honored.

  • Checked—All records will be extracted to the geodatabase. This option will override the Expand Feature Classes and Tables parameter value.
  • Unchecked—Only the schema will be extracted to the geodatabase for tables. This is the default.
