Default function not working

I’ve set the default value for a MySQL column to left(uuid(),8).

After using prisma introspect && prisma generate I get the following schema:

model game {
  id         String    @id @default("left(uuid(),8)")
}

Now, when using game.create prisma writes left(uuid(),8) into the id column.

I’ve tried setting id to null or undefined explicitly, but neither worked.

Is there any workaround for this?

Thanks.

Hi @baba43 — the syntax you used is for defining string defaults. If you want an expression as a default, you can use @default(dbgenerated("left(uuid(),8)"). I’d be curious to know if that works for you!

@baba43 If you can also share the SQL of this table, that would help in getting a more accurate reproduction.
