Prisma 6.7.0 upsert WhereUniqueInput compound unique additional non-unique fields extendedWhereUnique

💡 Result:

In Prisma 6.7.0, the extendedWhereUnique feature is no longer a Preview feature; it has been promoted to General Availability [1]. This functionality was originally introduced in version 4.5.0 [2] to allow developers to include additional non-unique fields in the where filter of queries that target unique records—such as findUnique, update, delete, and upsert—provided that at least one unique field is also specified [3][2]. Key details regarding your query: Compound Unique Constraints: You can use compound IDs or compound unique constraints within the where filter of an upsert operation [4][5]. When using these, you must provide the values for all fields that make up the unique constraint [4][5]. ExtendedWhereUnique: Because this feature is now part of the stable Prisma Client API, you do not need to enable any preview feature flags in your schema.prisma file to use it [1]. By allowing non-unique fields alongside unique fields in the where clause, it enables more precise targeting for operations like upsert [2]. For example, if you have a model with a unique id, you can perform an upsert using both that id and an additional non-unique status field: await prisma.user.upsert({ where: { id: 1, status: 'ACTIVE' // This non-unique field is now supported }, update: { name: 'New Name' }, create: { id: 1, name: 'New Name', status: 'ACTIVE' } }); Ensure that the fields used to identify the record in the where clause are defined as part of a @unique or @id constraint in your schema; otherwise, Prisma will raise a validation error because it cannot guarantee a single unique record match [6][7].

Scope upsert.where with the bound tenant.

upsert only stamps create, so a unique match from another tenant can enter the update branch. Apply applyTenantWriteScope to upsert.where after injection. Keep the unique selector at the top level. Add an extension-level regression test for the matching update branch.
