M Function Reference


Some capabilities may be present in one product but not others due to deployment schedules and host-specific capabilities.


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