Hey!

This seems like an issue with your project/application, the database you are trying to connect is called tanks_db but only the one called railway exists. Unfortunately, we're unable to offer support for issues unrelated to the Railway product or platform but our community might be able to help debug that!

Hello!

Could you please tell me where have you renamed it? Maybe a screenshot would help.

Thanks

The issue is all within Railway here are some screenshots. Thank you!

Thanks!

The MYSQL_DATABASE variable in Railway only tells your application which database name it should connect to — it doesn’t actually create or rename the database inside MySQL.

What you can do is:

- Keep the MYSQL_DATABASE variable set to tanks_db in your Railway settings.

- Connect to the MySQL server as root using MySQL Workbench (or any other client), with the MYSQL_ROOT_PASSWORD and the server host/port provided by Railway.

- Once connected, create the database manually by running:

CREATE DATABASE tanks_db;

After that, the tanks_db database should exist, and your application (as well as the Railway “Database” tab) should be able to connect to it normally.

Not sure if I was clear enough, but you can think of Railway as just a layer on top of what is actually running underneath.

The database itself lives inside its own “capsule”, and Railway only exposes a configuration layer around it.

So even if you change the database name in that outer layer, it doesn’t change what already exists inside the capsule.

Wonderful thank you! I will get this! So if I have multiple databases in this single capsule - can I reference them all from the outer layer? It is confusing there is only one place for a database name within the capsule when I am able to set up multiple. Thank you!

I have created the tanks_db database in Workbench and deleted the railway database. It still isn't connecting - it spins indefinitely. I am still using root to connect.

Disregard - I logged out and back in and it worked!
