Summary
RecordSet objects are a lightweight representation of a table. They are a special data element that contains not only schema but also the data. The RecordSet object is also how tables are sent and received from the server.
Discussion
Note:
If you're loading a table into a new RecordSet and modifying the RecordSet with a geoprocessing tool that modifies the input such as Calculate Field or a function such as UpdateCursor, the original table will also be modified.
Syntax
RecordSet ({table})
Parameter | Explanation | Data Type |
table | Table to be loaded into the RecordSet object. | String |
Properties
Property | Explanation | Data Type |
JSON (Read Only) | Returns an Esri JSON representation of the geometry as a string. Tip:The returned string can be converted to a dictionary using the Python json.loads function. | String |
Method Overview
Method | Explanation |
load (table_path, {where_clause}) | Import from a table. |
save (table_path) | Export to a table. |
Methods
load (table_path, {where_clause})
Parameter | Explanation | Data Type |
table_path | The table to be imported. The input can be a catalog path to a feature class, a URL to a hosted feature layer, or a URL JSON with the syntax {"url":"<url>", "token":"<token", "referer":"<referer>"} to load data from external sources that require an access token. | String |
where_clause | An SQL expression used to select a subset of records. For more information on SQL syntax, see SQL reference for query expressions used in ArcGIS. (The default value is None) | String |
The optional parameters are positional only; they cannot be passed by keyword.

Parameter | Explanation | Data Type |
table_path | The output table to be created. | String |
Code sample
Import a server toolbox; get the RecordSet from the server tool's specified parameter.
import arcpy
# Add a custom server toolbox
arcpy.ImportToolbox("http://myserver/arcgis/services;Geocode")
# Get recordset from server tool's first parameter to use as schema
in_recordset = arcpy.GetParameterValue("GeocodeAddress", 0)
Create a RecordSet and load a subset of a hosted table.
import arcpy
# Set data
in_dataset = "https://maps.my.org/arcgis/rest/services/Tables/MapServer/0"
query = "Country_Code: 'IT'"
# Create empty RecordSet
record_set = arcpy.RecordSet()
# Load data into RecordSet with query
record_set.load(in_dataset, query)
