[Sql Server] prisma migrate error when using multiple relations to the same table

Bug description

When I run npx prisma migrate dev --name initial with a schema like mine, the migration fails.

How to reproduce

• Create a prisma project with my schema.
• Create Azure SQL resources with this script
• replace the {SERVER} variables in the .env file (example)
• run npx prisma migrate dev --name initial --create-only
• the command will fail with the error message Database already exists FK__Address__userId
• after this error, the migrations table is totally broken and there’s nothing I can do to fix it, so I have to either drop all the objects or recreate the database
• There’s actually two errors here:

1. I want User to have multiple instances of Address, but Address shouldn’t have any relations with the User object. Because Prisma requires me to add this ‘Opposite Relation’, I created 3 distinct relations with the User object. All of them refer to the same FK, as indicated in this comment. Because all the relations point to the same column (userId), it should create just a single FK. Today, it’s trying to create 3, as you can see in the final migration file.

2. the error message is saying the the database already exists, but it should say Constraint already exists FK__Address__userId

Expected behavior

A successful migration is created and applied.

Oh, of course. that makes a lot of sense. it’s been a while since I last modeled a database. YOu inverted the FKs to make sure they’re present in the user/order objects instead of the Address object, right?

I’ll give this a go. If I find something weird, I’ll ping you. Thank you so much for your patience and help!

Error message should be less misleading in next release: https://github.com/prisma/prisma/issues/6547#issuecomment-822697209
