Is it possible to introspect relations?
Let's say I have the following relation def:
```js
export const externalUsersRelations = relations(external_users, ({one}) => ({
users: one(users, {
fields: [external_users.user_id],...
Polymorphic relationships using a discriminator column
Hi all,
I'm currently migrating (tbh rebuilding) a project that currently uses Entity Framework.
In the database, we currently have a few polymorphic relationships, represented with a discriminator column. E.g.
LicenseAssignments has a column LicenseTargetDiscriminator (which could be something like User, Organisation, Document, etc.) and a column LicenseTargetId which contains the ID of the resource in its particular table....JsonB and $type
I don't get how we're supposed to use jsonb types with drizzle-orm and drizzle-zod
if we use jsonb().$type<SomeType> then it seems that when we use createInsertSchema etc we still need to add a refinement for the field or we have type issues
I created some issues on the repo to have more infos, but perhaps someone here knows what are the best way to handle typed jsonb fields?

How to make a wrapper function for a table (after version 0.39.0)?
Prior tot 0.39.0 I could easily make a wrapper function for a table, but since 0.39 the typing broke and gives multiple typing errors (even though the code does run properly). See discussion here: https://github.com/drizzle-team/drizzle-orm/issues/4069#issuecomment-2692199268
But for who doesn't like to click through:
Same issue for all my table wrapper functions:...
Cannot be cast automatically
I've been struggling with this error for hours.

Hi. I started trying out drizzle (0.41.0) today and sql-like queries work pretty well. Unfortunately I have a problem with the findMany query when including relations.
I created a schema "studentsTable" and set a simple one-to-many relation at "dormId" to the schema "dormsTable". When querying with findMany() and trying to get the relation I always get
⨯ TypeError: Cannot read properties of undefined (reading 'referencedTable')
```export const studentsTable = pgTable("students", {...Generating/ applying migrations directly in code instead of using the CLI?
Hey! I use drizzle in both my frontend and backend via sqlite and postgres modules, one thing I've found annoying is that I have to generate migration files for tests, even thought I would just prefer to be able to infer the create table statements from the schemas themselves. Is this possible now?

Need help with relation
I have two tables: ...
characters and character_scores. They are linked by an id column. characters can have many of the same ID and character_scores as well. I want to make a relation between those ID's so that when I query a unique row from characters I want to include the associated character_scores row(s). So for example (pseudo sql):
from characters I want 1 row where id = x and specialization = y and include columns from character_scores where id = x and category = z
from characters I want 1 row where id = x and specialization = y and include columns from character_scores where id = x and category = z

Running multiple projects from one database
I'm pretty new to backend concepts and drizzle. I have created one project already using T3 stack + drizzle and have the database on Supabase.
It's deployed and working as expected but I am now looking at starting another project.
I am aware that the following bit of table creation code effectively allows me to run multiple projects on one database as all tables for that project are prefixed:...
GraphQL deeply nested relations

Seed local SQLite database from Remote D1 data?
Hi Drizzle team, I've been doing some basic testing of D1 with Drizzle and I've added some data to my remote D1 instance with Drizzle Studio. I see that the updated data is in my remote D1. However, when I migrate and run wrangler dev, I don't see my data in local. What am I missing?
