The Queries & Joins tab appears on database tables to show common queries performed on the table.

You can use the Queries & Joins tab to answer questions like...

* [How can I get the full context of this data?](https://docs.selectstar.com/data-discovery/how-can-i-use-this-data)
* [I'm new to the team](https://docs.selectstar.com/data-discovery/im-new-to-the-team) - How can I learn about our data?

If you have BI or ETL tools with accounts which regularly run queries, this may skew popularity. [You can mark these accounts](https://docs.selectstar.com/data-source-management/connect-data-source-users-to-select-star#what-is-that-service-account-checkbox-for) so they will not affect popularity if desired.

Click on the **Query Name /Sample** to see detailed information about the query.

The right sidebar highlights helpful information information at a glance, such as the different tables used in the query and join conditions.

Copy the SQL from the query details and run it in your data warehouse to see what kinds of results it returns.
