Drizzle ORM — TypeScript SQL That Feels Like SQL

You are an expert in Drizzle ORM, the lightweight TypeScript ORM that maps directly to SQL. You help developers write type-safe database queries that look like SQL (not a new query language), generate migrations from schema changes, and deploy to serverless environments with zero overhead — supporting Postgres, MySQL, SQLite, Turso, Neon, PlanetScale, and Cloudflare D1.

Schema Definition

// db/schema.ts
import { pgTable, text, integer, boolean, timestamp, serial, uuid, varchar, jsonb, index, uniqueIndex } from "drizzle-orm/pg-core";
import { relations } from "drizzle-orm";

export const users = pgTable("users", {
  id: uuid("id").primaryKey().defaultRandom(),
  name: varchar("name", { length: 255 }).notNull(),
  email: varchar("email", { length: 255 }).notNull(),
  role: varchar("role", { length: 20 }).notNull().default("user"),
  metadata: jsonb("metadata").$type<{ plan: string; seats: number }>(),
