Is this a hosted Wordpress site or are you hosting it yourself. If self-hosted, try this: 324: Finding Your Database Name in WordPress | InMotion Hosting
If hosted by another provider, I'd be very surprised if they'd give you direct access to the database.
Thanks Ken Flerlage
We are Using Digital Ocean to host the site.
If I understand that article correctly I only need my db name to connect? How does tableau know where to search for that dbname with no other url connection string?
