Prisma

I just read an article that `migrate deploy` command doesn't rely on the schema file for migrations. From where does it fetch the DB URL?

It does read the schema for the if the database URL is defined directly or via an environment variable defined.

Can you share the link to the docs where this is written?

<https://www.prisma.io/docs/concepts/components/prisma-migrate#source-controlling-the-migration-history>

```The prisma migrate deploy command, which is used to deploy changes to staging, testing, and production environments, only runs migration files. It does not use the Prisma schema file.```

This means that it does not use the models defined in your `schema.prisma` but the `.sql` files from the `migrations` folder.

It does read your `schema.prisma` as without that it wouldn’t know the environment variable for the database URL.

We should add that to the last sentence <@UESADRKMY>. Something like "... to get the data model."
