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
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.
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.

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 Teradata database.
