Applies to: SQL Server SSIS Integration Runtime in Azure Data Factory
Use the OData Source component in an SSIS package to consume data from an Open Data Protocol (OData) service.
Supported protocols and data formats
The component supports the OData v3 and v4 protocols.
For OData V3 protocol, the component supports the ATOM and JSON data formats.
For OData V4 protocol, the component supports the JSON data format.
Supported data sources
The OData source includes support for the following data sources:
- Microsoft Dynamics AX Online and Microsoft Dynamics CRM Online
- SharePoint lists. To see all the lists on a SharePoint server, use the following URL:
https://<server>/_vti_bin/ListData.svc. For more information about SharePoint URL conventions, see SharePoint Foundation REST Interface.
Supported data types
The OData source supports the following simple data types: int, byte, bool, byte, DateTime, DateTimeOffset, decimal, double, Guid, Int16, Int32, Int64, sbyte, float, string, and TimeSpan.
To discover the data types of columns in your data source, check the
https://<OData feed endpoint>/$metadata page.
For the Decimal data type, the precision and scale are determined by the source metadata. If the source metadata does not specify the Precision and Scale properties, the data may be truncated.
The OData Source component does not support complex types, such as multiple-choice items, in SharePoint lists.
If the source only allows TLS 1.2 connection, you need to enforce TLS 1.2 on your machine through registry settings. In an elevated command prompt run the following commands:
reg add HKLM\SOFTWARE\Microsoft.NETFramework\v4.0.30319 /v SchUseStrongCrypto /t REG_DWORD /d 1 /reg:64
reg add HKLM\SOFTWARE\Microsoft.NETFramework\v4.0.30319 /v SchUseStrongCrypto /t REG_DWORD /d 1 /reg:32
OData Format and Performance
Most OData services can return results in multiple formats. You can specify the format of the result set by using the
$format query option. Formats such as JSON and JSON Light are more efficient than ATOM or XML, and may give you better performance when transferring large amounts of data. The following table provides results from sample tests. As you can see, there was a 30-53% performance gain when switching from ATOM to JSON and a 67% performance gain when switching from ATOM to the new JSON light format (available in WCF Data Services 5.1).

OData Source Editor (Connection Page)
Use the Connection page of the OData Source Editor dialog box to select the OData connection manager for the OData source. This page also lets you specify a collection or a resource path and any query options to indicate what data needs to be retrieved from the OData source.
OData connection manager
Select an existing connection manager from the list, or create a new connection by clicking New.
After you select or create a connection manager, the dialog box displays the OData protocol version that the connection manager is using.
Create a new connection manager by using the OData Connection Manager Editor dialog box.
Use collection or resource path
Specify the method for selecting data from the source.
|Collection||Retrieve data from the OData source by using a collection name.|
|Resource Path||Retrieve data from the OData source by using a resource path.|
Specify options for the query. For example:
Displays the read-only feed URL based on options you selected on this dialog box.
Preview results by using the Preview dialog box. Preview can display up to 20 rows.
Use collection or resource path = Collection
Select a collection from the drop-down list.
Use collection or resource path = Resource Path
Type a resource path. For example: Employees
OData Source Editor (Columns Page)
Use the Columns page of the OData Source Editor dialog box to select external (source) columns to be included in the output and map them to output columns.
Available External Columns
View the list of available source columns in the data source. Use check boxes in the list to add to or remove columns to the table at the bottom of the page. The selected columns are added to the output.
View source columns that you chose to be included in the output.
Provide a unique name for each output column. The default is the name of the selected external (source) column; however, you can choose any unique, descriptive name.
OData Source Editor (Error Output Page)
Use the Error Output page of the OData Source Editor dialog box to select error handling options and to set properties on error output columns.
View the name of the data source.
View the external (source) columns that you selected on the Connection Manager page of the OData Source Editor dialog box.
Specify what should happen when an error occurs: ignore the failure, redirect the row, or fail the component.
