In addition to looking at a table's column, you can also look at its connections if your table includes any. Connections show up here if there’s a column in the table you’re looking at that’s included in another table (i.e., a foreign key relationship). Click on **Connections** (located next to the **Fields** button) to view the connected tables.
### Foreign keys
You can find a list of connections to other tables (i.e., [foreign key](/glossary/foreign_key) relationships) under **Connected to these tables**. If there’s a column in the table you’re looking at that’s included in another table, Metabase will display this section in the sidebar. Note that connections are managed by your Metabase admin. If a foreign key relationship exists in your database, but not in your Metabase, your Metabase admin will need to update your [Metabase data model](../administration-guide/03-metadata-editing.md).

When you run a query from the SQL editor, Metabase sends the query to your database exactly as it is written. Any results or errors displayed in Metabase are the same as the results or errors that you would get if you ran the query directly against your database. If the SQL syntax of your query doesn’t match the SQL dialect used by your database, your database won’t be able to run the query.
## How Metabase executes SQL variables
When your query includes a SQL variable, the `{% raw %}{{#5}}{% endraw %}` tag will be substituted with the SQL query of the referenced question or model, surrounded by parentheses.
For an example, see the documentation on [Referencing models and saved questions in SQL queries](../users-guide/referencing-saved-questions-in-queries.html).
