*

*
* For example, to get the `home` option for your second site, modify the example above like so:
*
* $ wp db query 'SELECT option_value FROM wp_2_options WHERE option_name="home"' --skip-column-names
* +----------------------+
* | https://example2.com |
* +----------------------+
*
* To confirm the ID for the site you want to query, you can use the `wp site list` command:
*
* # wp site list --fields=blog_id,url
* +---------+-----------------------+
* | blog_id | url |
* +---------+-----------------------+
* | 1 | https://example1.com/ |
* | 2 | https://example2.com/ |
