  3. Optionally, enter values in any advanced options that you want to use to modify the connection query, such as a text value to use as a Role name or a command timeout. More information: Connect using advanced options

  4. Select OK.

    Note

    Once you enter your username and password for a particular Snowflake server, Power BI Desktop uses those same credentials in subsequent connection attempts. You can modify those credentials by going to File > Options and settings > Data source settings. More information: Change the authentication method

    If you want to use the Microsoft account option, the Snowflake Microsoft Entra ID integration must be configured on the Snowflake side. More information: Power BI SSO to Snowflake - Getting Started

  6. In Navigator, select one or multiple elements to import and use in Power BI Desktop. Then select either Load to load the table in Power BI Desktop, or Transform Data to open the Power Query Editor where you can filter and refine the set of data you want to use, and then load that refined set of data into Power BI Desktop.

Connect using advanced options

Power Query provides a set of advanced options that you can add to your query if needed.

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

Advanced option Description
Role name Specifies the role that the report uses via the driver. This role must be available to the user, otherwise no role is set.
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.
Connection timeout in seconds Specifies how long to wait for a response when interacting with the Snowflake service before returning an error. Default is 0 (no timeout).
Command timeout in seconds Specifies how long to wait for a query to complete before returning an error. Default is 0 (no timeout).
Database Specifies a specific database in the warehouse. This option is only available in Power Query Desktop.
SQL Statement For information, go to Import data from a database using native database query. This option is only available in Power Query Desktop.

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 Snowflake database.

Troubleshooting

Error: SQL compilation error: Object does not exist, or operation cannot be performed

The error occurs when the system can't find the specified object. Often, this error is due to the user having an invalid database name set as their default database.

Ensure that a valid default database name is used for the property DEFAULT_NAMESPACE: DESC USERusername

To update the default database name: alter userusername set DEFAULT_NAMESPACE=<database name>.<schema name>. For more information, see the Snowflake documentation - https://docs.snowflake.com/en/sql-reference/sql/alter-user

Limitations and known issues

Hyphens in database names

If a database name has a hyphen in it, you can encounter an ODBC: ERROR[42000] SQL compilation error. This issue is addressed in the September 2024 release.

Slicer visual for Boolean datatype

The slicer visual for the Boolean data type isn't functioning as expected in the June 2024 release. This is a known issue. As a temporary solution, users can convert the Boolean data type in their reports to text by navigating to: Transfer -> Data Type -> Text. A fix will be provided in October 2024 release.
