Feature Class To Feature Class (Conversion)

Summary

Converts a feature class or feature layer to a feature class.

Legacy:

This is a deprecated tool. This functionality has been replaced by the Export Features tool.

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 details about the syntax for the Expression parameter, see SQL reference for query expressions used in ArcGIS.

• When converting geodatabase data that has subtypes or domains to a shapefile, both the subtype and domain codes and descriptions can be included in the output. Use the Transfer field domain descriptions geoprocessing environment to do this. By default, only domain and subtype codes will be included in the output, not descriptions.

  Note:

  Converting 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, leave the Transfer field domain descriptions environment unchecked (False or NOT_TRANSFER_DOMAINS in Python) for best performance.

Parameters

Dialog

Label	Explanation	Data Type
Input Features	The feature class or feature layer that will be converted.	Feature Layer
Output Location	The location where the output feature class will be created. This can be either a geodatabase or a folder. If the output location is a folder, the output will be a shapefile.	Workspace;Feature Dataset
Output Name	The name of the output feature class.	String
Expression (Optional)	An SQL expression used to select a subset of features.	SQL Expression
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 will be merged or combined into a single output value. The following merge rules can be used to determine how the output field will be populated with values: First—Use the input fields' first value. Last—Use the input fields' last value. Join—Concatenate (join) the input field values. Sum—Calculate the total of the input field values. Mean—Calculate the mean (average) of the input field values. Median—Calculate the median (middle) of the input field values. Mode—Use the value with the highest frequency. Min—Use the minimum value of all the input field values. Max—Use the maximum value of all the input field values. Standard deviation—Use the standard deviation classification method on all the input field values. Count—Find the number of records included in the calculation.	Field Mappings
Configuration Keyword (Optional)	Specifies the default storage parameters (configurations) for geodatabases in a relational database management system (RDBMS). This setting is applicable only when using enterprise geodatabase tables. Configuration keywords are set by the database administrator. Learn more about configuration keywords	String

Derived Output

Label	Explanation	Data Type
Output Feature Class	The output feature class.	Feature Class

arcpy.conversion.FeatureClassToFeatureClass(in_features, out_path, out_name, {where_clause}, {field_mapping}, {config_keyword})

Name	Explanation	Data Type
in_features	The feature class or feature layer that will be converted.	Feature Layer
out_path	The location where the output feature class will be created. This can be either a geodatabase or a folder. If the output location is a folder, the output will be a shapefile.	Workspace;Feature Dataset
out_name	The name of the output feature class.	String
where_clause (Optional)	An SQL expression used to select a subset of features. For more information on SQL syntax see the help topic SQL reference for query expressions used in ArcGIS.	SQL Expression
field_mapping (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 will be merged or combined into a single output value. The following merge rules can be used to determine how the output field will be populated with values: First—Use the input fields' first value. Last—Use the input fields' last value. Join—Concatenate (join) the input field values. Sum—Calculate the total of the input field values. Mean—Calculate the mean (average) of the input field values. Median—Calculate the median (middle) of the input field values. Mode—Use the value with the highest frequency. Min—Use the minimum value of all the input field values. Max—Use the maximum value of all the input field values. Standard deviation—Use the standard deviation classification method on all the input field values. Count—Find the number of records included in the calculation. In Python, you can use the FieldMappings class to define this parameter.	Field Mappings
config_keyword (Optional)	Specifies the default storage parameters (configurations) for geodatabases in a relational database management system (RDBMS). This setting is applicable only when using enterprise geodatabase tables. Configuration keywords are set by the database administrator. Learn more about configuration keywords	String

Code sample

FeatureClassToFeatureClass example 1 (Python window)

The following Python window script demonstrates how to use the FeatureClassToFeatureClass function in immediate mode.

import arcpy
arcpy.env.workspace = "C:/data/GreenvalleyDB.gdb/Public Buildings"
arcpy.conversion.FeatureClassToFeatureClass("buildings_point", 
                                            "C:/output/output.gdb", 
                                            "buildings_point")

FeatureClassToFeatureClass example 2 (stand-alone script)

The following stand-alone script demonstrates how to use the FeatureClassToFeatureClass function.

# Name: FeatureClassToFeatureClass_Example2.py
# Description: Use FeatureClassToFeatureClass 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/GreenvalleyDB.gdb/Public Buildings"
 
# Set local variables
inFeatures = "buildings_point"
outLocation = "C:/output/output.gdb"
outFeatureClass = "postoffices"
delimitedField = arcpy.AddFieldDelimiters(arcpy.env.workspace, "NAME")
expression = delimitedField + " = 'Post Office'"
 
# Run FeatureClassToFeatureClass
arcpy.conversion.FeatureClassToFeatureClass(inFeatures, outLocation, 
                                            outFeatureClass, expression)
