            <h5>Database Access</h5>
            <p>
              Setting the database for this datasource does not deny access to other databases. The InfluxDB query
              syntax allows switching the database in the query. For example:
              <code>SHOW MEASUREMENTS ON _internal</code> or <code>SELECT * FROM "_internal".."database" LIMIT 10</code>
              <br />
              <br />
              To support data isolation and security, make sure appropriate permissions are configured in InfluxDB.
