hey @Raphaël M (@rphlmr) ⚡ just FYI, thanks to your example and some googling I just understood how recursive query works, and even been able to write my own that takes current category and lists all its the the parents recursively 😅

well hopefully one day I'll uinderstand some of these typings 😅 other than that, you're a ⭐ thank you!

well TS is great, but I have no idea how people do come up with all these typings, that's madness, then recursion on itself is easy 🤣

well for now I did this manually 🤣 
export type Category = typeof CategoryTable.$inferSelect;

export type CategorySub = {
  categoryId: number;
  childId: number;
  category: CategoryChildren;
};

export type CategoryChildren = Category & {
  children: CategorySub[];
};

export type CategoryWithChildren = CategoryChildren | undefined;
export type Category = typeof CategoryTable.$inferSelect;

export type CategorySub = {
  categoryId: number;
  childId: number;
  category: CategoryChildren;
};

export type CategoryChildren = Category & {
  children: CategorySub[];
};

export type CategoryWithChildren = CategoryChildren | undefined;
works ok'ish

Self referencing table query
although typing the result of these 
with: {
      children: {
        with: {
          child: {
            with: {
              children: {
                with: {
                  child: true,
                },
              },
            },
          },
        },
      },
    },
with: {
      children: {
        with: {
          child: {
            with: {
              children: {
                with: {
                  child: true,
                },
              },
            },
          },
        },
      },
    },
is a nightmare for me 🤨

well again thank you! although that is such a madness that I'll just stick to the nested with solution posted above, as at least I understand what's going on 🤣

not sure if that's a drizzle only question but maybe you'll be able to point me to a proper solution with drizzle

Self referencing table query
my second approach after your help was to do it the other way, to have a separate column and many relation, but that's more complicated: 
export const CategoryTable = pgTable('category', {
  id: serial('id').primaryKey().unique(),
  slug: varchar('slug', { length: 128 }).notNull().unique(),
  name: varchar('name', { length: 128 }).notNull().unique(),
  image: varchar('image', { length: 1024 }).notNull(),
  description: text('description').notNull(),
});

export const CategoryRelations = relations(CategoryTable, ({ many }) => ({
  children: many(CategoryToChildTable, { relationName: 'parent' }),
}));

export const CategoryToChildTable = pgTable(
  'category_to_child',
  {
    categoryId: integer('category_id')
      .notNull()
      .references(() => CategoryTable.id),
    childId: integer('child_id')
      .notNull()
      .references(() => CategoryTable.id),
  },
  (tbl) => ({
    pk: primaryKey({ columns: [tbl.categoryId, tbl.childId] }),
  }),
);

export const CategoryToChildRelations = relations(
  CategoryToChildTable,
  ({ one }) => ({
    parent: one(CategoryTable, {
      relationName: 'parent',
      fields: [CategoryToChildTable.categoryId],
      references: [CategoryTable.id],
    }),
    child: one(CategoryTable, {
      relationName: 'child',
      fields: [CategoryToChildTable.childId],
      references: [CategoryTable.id],
    }),
  }),
);
export const CategoryTable = pgTable('category', {
  id: serial('id').primaryKey().unique(),
  slug: varchar('slug', { length: 128 }).notNull().unique(),
  name: varchar('name', { length: 128 }).notNull().unique(),
  image: varchar('image', { length: 1024 }).notNull(),
  description: text('description').notNull(),
});

export const CategoryRelations = relations(CategoryTable, ({ many }) => ({
  children: many(CategoryToChildTable, { relationName: 'parent' }),
}));

export const CategoryToChildTable = pgTable(
  'category_to_child',
  {
    categoryId: integer('category_id')
      .notNull()
      .references(() => CategoryTable.id),
    childId: integer('child_id')
      .notNull()
      .references(() => CategoryTable.id),
  },
  (tbl) => ({
    pk: primaryKey({ columns: [tbl.categoryId, tbl.childId] }),
  }),
);

export const CategoryToChildRelations = relations(
  CategoryToChildTable,
  ({ one }) => ({
    parent: one(CategoryTable, {
      relationName: 'parent',
      fields: [CategoryToChildTable.categoryId],
      references: [CategoryTable.id],
    }),
    child: one(CategoryTable, {
      relationName: 'child',
      fields: [CategoryToChildTable.childId],
      references: [CategoryTable.id],
    }),
  }),
);
that can be queried with: 
db.query.CategoryTable.findMany({
    where: eq(CategoryTable.slug, ''),
    with: {
      children: {
        with: {
          child: {
            with: {
              children: {
                with: {
                  child: true,
                },
              },
            },
          },
        },
      },
    },
  });
db.query.CategoryTable.findMany({
    where: eq(CategoryTable.slug, ''),
    with: {
      children: {
        with: {
          child: {
            with: {
              children: {
                with: {
                  child: true,
                },
              },
            },
          },
        },
      },
    },
  });

Self referencing table query
hey @Raphaël M (@rphlmr) ⚡ me again 😅 so as I mentiond at the beginning, what I was tring to achieve was to have CATEGORIES table for a samll shop, where each category can have 1 parent or null (top category) then what I would need is to have a way to query all of them in a tree like structure, top to bottom, which seems to be done in sql with "recursive" but that's still not yet available in drizzle and if I have: 
export const CategoryTable = pgTable(
  'category',
  {
    id: serial('id').primaryKey().unique(),
    parent_id: integer('parent_id').references(
      (): AnyPgColumn => CategoryTable.id,
    ),
    slug: varchar('slug', { length: 128 }).notNull().unique(),
    name: varchar('name', { length: 128 }).notNull().unique(),
    image: varchar('image', { length: 1024 }).notNull(),
    description: text('description').notNull(),
  },
  (table) => {
    return {
      slug_idx: index('slug_idx').on(table.slug),
    };
  },
);

export const CategoryRelations = relations(CategoryTable, ({ one }) => ({
  parent: one(CategoryTable, {
    fields: [CategoryTable.parent_id],
    references: [CategoryTable.id],
  }),
}));
export const CategoryTable = pgTable(
  'category',
  {
    id: serial('id').primaryKey().unique(),
    parent_id: integer('parent_id').references(
      (): AnyPgColumn => CategoryTable.id,
    ),
    slug: varchar('slug', { length: 128 }).notNull().unique(),
    name: varchar('name', { length: 128 }).notNull().unique(),
    image: varchar('image', { length: 1024 }).notNull(),
    description: text('description').notNull(),
  },
  (table) => {
    return {
      slug_idx: index('slug_idx').on(table.slug),
    };
  },
);

export const CategoryRelations = relations(CategoryTable, ({ one }) => ({
  parent: one(CategoryTable, {
    fields: [CategoryTable.parent_id],
    references: [CategoryTable.id],
  }),
}));
I can query everything using with but then it goes bottom to top, so the other way around is there a way to solve that in drizzle at the moment?

hey @Raphaël M (@rphlmr) ⚡ one more question, is there any difference in using ". references" vs using the extraConfig?

ahh that makes sense, seems I'll just migrate to postgres as seems there's many more tutorials for it, and at that point it doesn't make any difference for me
