Power BI Desktop and the Power BI service have many data sources to which you can connect and get access to data. This article describes which data sources for Power BI support the connection method known as DirectQuery. For more information about DirectQuery, see DirectQuery in Power BI.

The following data sources support DirectQuery in Power BI:

  • Amazon Redshift
  • AtScale (Beta)
  • Azure Data Explorer
  • Azure HDInsight Spark
  • Azure SQL Database
  • Azure SQL Data Warehouse
  • Google BigQuery
  • HDInsight Interactive Query
  • IBM DB2 database
  • IBM Netezza
  • Impala (version 2.x)
  • Oracle Database (version 12 and above)
  • Oracle Essbase
  • SAP Business Warehouse Application Server
  • SAP Business Warehouse Message Server
  • SAP HANA
  • Snowflake
  • Spark (version 0.9 and above)
  • SQL Server
  • Teradata Database
  • Vertica

Data sources that have (Beta) or (Preview) after their name are subject to change, and are not supported for production use. They might also not be supported after publishing a report to the Power BI service, which means that opening a published report or exploring the dataset can result in an error.

The only difference between (Beta) and (Preview) data sources is that (Preview) sources must be enabled as a Preview feature before they become available for use. To enable a (Preview) data connector, in Power BI Desktop go to File > Options and Settings > Options, and then select Preview features.

Note

DirectQuery queries to SQL Server require authentication using current Windows authentication credentials or database credentials to establish access. Alternate credentials are not supported.

On-premises gateway requirements

Single sign-on (SSO) for DirectQuery sources

When the SSO option is enabled and your users access reports built atop the data source, Power BI sends their authenticated Azure AD credentials in the queries to the underlying data source. This enables Power BI to respect the security settings that are configured at the data source level.

The SSO option takes affect across all datasets that use this data source. It does not affect the authentication method used for import scenarios. The following data sources support SSO for connections through DirectQuery:

  • Azure SQL Database
  • Azure SQL Data Warehouse
  • Impala
  • SAP HANA
  • SAP BW
  • Spark
  • SQL Server
  • Teradata

Note

Azure Multi-Factor Authentication (MFA) is not supported. Users who want to use SSO with DirectQuery must be exempted from MFA.
