Power Query Source (Preview)

APPLIES TO: yesSQL Server, including on Linux yesAzure SQL Database yesAzure SQL Data Warehouse noParallel Data Warehouse

This article describes how to configure the properties of the Power Query Source in the SQL Server Integration Services (SSIS) data flow. Power Query is a technology that allows you to connect to various data sources and transform data using Excel/Power BI Desktop. For more info, see Power Query - Overview and Learning article. The script generated by Power Query can be copied & pasted into the Power Query Source in the SSIS data flow to configure it.


For the current preview release, to facilitate quick feedback-gathering and frequent feature enhancements, Power Query Source can only be used in SQL Server Data Tools (SSDT) and Azure-SSIS Integration Runtime (IR) in Azure Data Factory (ADF). You can download the latest SSDT that supports the Power Query Source from here. To provision Azure-SSIS IR, see Provision SSIS in ADF article.

Configure the Power Query Source

To open Power Query Source Editor in SSDT, drag & drop Power Query Source from SSIS Toolbox onto the data flow designer and double-click on it.

PQ Source

Three tabs are shown on the left side. On Queries tab, you can select your query mode from the dropdown menu.

  • Single Query mode allows you to copy & paste a single Power Query script from Excel/Power BI Desktop.
  • Single Query from Variable mode allows you to specify a string variable that contains your query to be executed.

PQ Source Queries Tab Single

On Connection Managers tab, you can add or remove Power Query connection managers that contain data source access credentials. Selecting the Detect Data Source button identifies the referenced data sources in your query and lists them for you to assign the appropriate existing Power Query connection managers or create new ones.

Finally, on Columns tab, you can edit the output column info.

Configure the Power Query Connection Manager

When designing your data flow with Power Query Source on SSDT, you can create a new Power Query Connection Manager in the following ways:

  • Indirectly create it on Connection Managers tab of Power Query Source after selecting Add/Detect Data Source button and selecting from the dropdown menu as described above.
  • Directly create it by right-clicking on Connection Managers panel of your package and selecting New Connection... from the dropdown menu.

PQ Source Connection Managers Panel Add

In Add SSIS Connection Manager dialog, double-click on PowerQuery from the list of connection manager types.

In Power Query Connection Manager Editor, you need to specify Data Source Kind, Data Source Path, and Authentication Kind, as well as assign the appropriate access credentials. For Data Source Kind, you can currently select one of 22 kinds from the dropdown menu.

PQ Source Connection Manager Editor Kind

Some of these sources (Oracle, DB2, MySQL, PostgreSQL, Teradata, Sybase) require additional installations of ADO.NET drivers that can be obtained from Power Query Prerequisites article. You can use the custom setup interface to install them on your Azure-SSIS IR, see Customizing Azure-SSIS IR article.

For Data Source Path, you can enter data source-specific properties forming a connection string without the authentication info. For example, the path for SQL data source is formed as <Server>;<Database>. You can select the Edit button to assign values to data source-specific properties forming the path.

Finally, For Authentication Kind, you can select Anonymous/Windows Authentication/Username Password/Key from the dropdown menu, enter the appropriate access credentials, and select the Test Connection button to ensure that Power Query Source has been properly configured.

Current limitations

  • Oracle data source can not currently be used, because Oracle ADO.NET driver can not be installed on Azure-SSIS IR, so please install Oracle ODBC driver instead and use ODBC data source to connect to Oracle for now, see ORACLE STANDARD ODBC example in Customizing Azure-SSIS IR article.

  • Web data source can not currently be used on Azure-SSIS IR with custom setup, so please use it on Azure-SSIS IR without custom setup for now.
