how to run migrations by code

I have a project with a main database, called general and inside it a table of companies, each company has a different database. My problem is the following, in this project I use the typeorm, but I am considering migrating to the prisma, the problem is that in the typeorm I can run the migrations inside the connection.

await connection.runMigrations({
       transaction: 'all',
});

Is there any way to get it to run in the same way as typeorm here in prisma??

I can connect to another db with a custom url:

import { PrismaClient } from '@prisma/client'

const client1 = new PrismaClient({ datasources: { db: { url: 'postgres://localhost/db1' }} })

@janpio I have a use case for you. We’re trying out https://github.com/testcontainers/testcontainers-node and we would like each of our test cases to bring up their own containers (postgres in this case), migrate the full database using Prisma programmatic API which will be fed with the temporal hosts/ports given from testcontainers (because it assigns different ones in each container) and then have all test cases run in parallel.

So programmatic access to Prisma will allow us to do that in just a cleaner way instead of running a script directly from the test case. Thanks, hope that makes sense
