Prerequisites

By default, Power BI installs an OLE DB driver for Azure Synapse Analytics (SQL DW). However, for optimal performance, we recommend that the customer installs the SQL Server Native Client before using the Azure Synapse Analytics (SQL DW) connector. SQL Server Native Client 11.0 and SQL Server Native Client 10.0 are both supported in the latest version.

Capabilities Supported

  • Import
  • DirectQuery (Power BI only)
  • Advanced options
    • Command timeout in minutes
    • Native SQL statement
    • Relationship columns
    • Navigate using full hierarchy
    • SQL Server failover support

Display of advanced options available in Power Query Desktop

The following table lists all of the advanced options you can set in Power Query Desktop and Power Query Online.

Advanced option Description
Command timeout in minutes If your connection lasts longer than 10 minutes (the default timeout), you can enter another value in minutes to keep the connection open longer. This option is only available in Power Query Desktop.
SQL statement For information, go to Import data from a database using native database query.
Include relationship columns If checked, includes columns that might have relationships to other tables. If this box is cleared, you won’t see those columns.
Navigate using full hierarchy If checked, the navigator displays the complete hierarchy of tables in the database you're connecting to. If cleared, the navigator displays only the tables whose columns and rows contain data.
Enable SQL Server Failover support If checked, when a node in the Azure SQL failover group isn't available, Power Query moves from that node to another when failover occurs. If cleared, no failover occurs.

Once you've selected the advanced options you require, select OK in Power Query Desktop or Next in Power Query Online to connect to your Azure SQL database.
