| Label | Explanation | Data Type |
Input Features
| The input features to be exported to a new feature class. | Feature Layer |
Output Feature Class
| The output feature class containing the exported features. | Feature Class |
Expression
(Optional) | An SQL expression used to select a subset of features. | SQL Expression |
Use Field Alias as Name
(Optional) | Specifies whether the input's field names or field aliases will be used as the output field name.
| Boolean |
Field Map
(Optional) | The attribute fields that will be in the output with the corresponding field properties and source fields. By default, all fields from the inputs will be included. Fields can be added, deleted, renamed, and reordered, and you can change their properties. Merge rules allow you to specify how values from two or more input fields are merged or combined into a single output value. There are several merge rules you can use to determine how the output field will be populated with values.
| Field Mappings |
Sort Field (Optional) | The field or fields whose values will be used to reorder the input records and the direction the records will be sorted.
| Value Table |
Summary
Exports the rows of a feature class or feature layer to a feature class.
Usage
To manage the fields in the output dataset and the contents of those fields, use the Field Map parameter.
- To change the field order, select a field name and drag it to the new position.
- The default data type of an output field is the same as the data type of the first input field (of that name) it encounters. You can manually change the data type at any time to any other valid data type.
- The available merge rules are first, last, join, sum, mean, median, mode, minimum, maximum, standard deviation, and count.
- When using the Join merge rule, you can specify a delimiter such as a space, comma, period, dash, and so on. To use a space, ensure that the pointer is at the start of the input box and press the Spacebar once.
- You can specify the start and end positions of text fields using the format option.
- Do not perform standard deviation on a single input because values cannot be divided by zero, so standard deviation is not a valid option for single inputs.
An SQL expression can be used to select a subset of features. For more information about the syntax for the Expression parameter, see SQL reference for query expressions used in ArcGIS.
Rows can be reordered in ascending or descending order by specifying the Sort Field parameter value. If more than one field is specified, rows will be sorted by the first field, and within that order, by the second field, and so on.
When converting geodatabase data that has subtypes or domains, both the subtype and domain codes and descriptions can be included in the output. Use the Transfer field domain descriptions environment to control this behavior. By default, only domain and subtype codes will be included in the output, not descriptions.
Note:
Conversion to shapefiles with subtype and domain descriptions may take more time (slower performance) than without descriptions. If subtype and domain descriptions are not required in the output, it is recommended that you use the default setting (unchecked) for the Transfer field domain descriptions environment for best performance.

Code sample
The following Python window script demonstrates how to use the ExportFeatures function in immediate mode.
import arcpy
arcpy.env.workspace = "C:/data/SFValley.gdb"
arcpy.conversion.ExportTable("streets", "C:/output/output.gdb/streets")The following stand-alone script demonstrates how to use the ExportFeatures function.
# Name: ExportFeatures_Example2.py
# Description: Use Export Features with an expression to create a subset of the
# original feature class.
# Import system modules
import arcpy
# Set environment settings
arcpy.env.workspace = "C:/data/SFValley.gdb"
# Set local variables
inFeatures = "streets"
outFeatureClass = "C:/output/output.gdb/arterials"
expression = arcpy.AddFieldDelimiters(arcpy.env.workspace, "Category") + " = 'Arterials'"
# Execute ExportFeatures
arcpy.ExportTable_conversion(inFeatures, outFeatureClass, expression,
"NOT_USE_ALIAS", None, None)Environments
