OData Source

  • Άρθρο

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.

Important

The OData Source component does not support complex types, such as multiple-choice items, in SharePoint lists.

Note

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).

Rows ATOM JSON JSON (Light)
10000 113 seconds 74 seconds 68 seconds
1000000 1110 seconds 853 seconds 665 seconds

OData Source Editor (Connection Page)
