"Implementing a unique constraint in Drizzle-orm PostgreSQL with the additional condition of deleted_at being

Is there a way to construct a table using a WHEN SQL tag?

I am interested in setting up a table similar to this:

"members_table",   {     id: serial("id").primaryKey(),     email: text("email").notNull(),     team_id: text("team_id").notNull(),     deleted_at: timestamp("deleted_at"),   },

I would like the uniqueness constraint to be implemented as follows:

CREATE UNIQUE INDEX email_team_id_unique_idx ON members_table (email, team_id) WHERE deleted_at IS NULL;

But in Drizzle. Can this be achieved?

I want to ensure that the same email and team_id cannot be duplicated. For example, [email protected] cannot exist in both team_id A and B, while [email protected] can be in A with deleted_at as NULL, and [email protected] can be in A with deleted_at set to August 15th, 2024 simultaneously. I hope this clarifies things.

I am working with Next.js, Neon, and PostgreSQL if that influences anything 🙂

I have experimented quite a bit, but without success. I am still relatively new to Drizzle and with a vast amount of documentation, it can be challenging to pinpoint exactly what I need. Any suggestions are appreciated, as there is a good chance you may have more knowledge on the subject than I do xD

Answer â„–1

Wow, I must admit I made a silly mistake just now. It turns out that my issue was caused by importing the wrong file for the uniqueIndex function. After realizing my error and changing the import to pg-core, everything started working properly. Lesson learned!
