Suggested way to query equivalent to prisma's findUnique

In prisma, if I specify an index on 3 fields (say field1, field2, and field3), I am able to query on that unique combination and do something like so:

await prisma.someTable.findUnique({
  where: {
    field1_field2_field3: { // This type requires all 3 specified
      field1: 'asdf',
      field2: 'asdf',
      field3: 'asdf'
    }
  }
});

await prisma.someTable.findUnique({
  where: {
    field1_field2_field3: { // This type requires all 3 specified
      field1: 'asdf',
      field2: 'asdf',
      field3: 'asdf'
    }
  }
});

Is there anything analogous in drizzle? The only workaround I see online is to just create a new field to represent the index, but that seems very hacky.

I believe this may just be a missing feature. There should be some way to have a findUnique function that is essentially a copy of findFirst except with different type defs for the where clause based on where the unique indexes are defined.

There is still no feature parity between Prisma and drizzle yet. I personally don't have any idea what that API is doing for you under the hood? Is it just filtering by those 3 fields? Is it looking at your actual indexes making sure is unique? Does it throw and error if more that one is received back? Does it add a limit 1 to the query? I would suggest to find out what is it that you need from findUnique exactly, in terms of SQL queries, and go from there.

i will clarify in a comment in the GH thread added very detailed comment with type interface + examples
