Drizzle ORM - Goodies

Type API

To retrieve a type from your table schema for select and insert queries, you can make use of our type helpers.

PostgreSQL

MySQL

SQLite

SingleStore

import { serial, text, pgTable } from 'drizzle-orm/pg-core';
import { type InferSelectModel, type InferInsertModel } from 'drizzle-orm'

const users = pgTable('users', {
  id: serial('id').primaryKey(),
  name: text('name').notNull(),
});

type SelectUser = typeof users.$inferSelect;
type InsertUser = typeof users.$inferInsert;
// or
type SelectUser = typeof users._.$inferSelect;
type InsertUser = typeof users._.$inferInsert;
// or
type SelectUser = InferSelectModel<typeof users>;
type InsertUser = InferInsertModel<typeof users>;

import { int, text, mysqlTable } from 'drizzle-orm/mysql-core';
import { type InferSelectModel, type InferInsertModel } from 'drizzle-orm'

const users = mysqlTable('users', {
  id: int('id').primaryKey(),
  name: text('name').notNull(),
});

type SelectUser = typeof users.$inferSelect;
type InsertUser = typeof users.$inferInsert;
// or
type SelectUser = typeof users._.$inferSelect;
type InsertUser = typeof users._.$inferInsert;
// or
type SelectUser = InferSelectModel<typeof users>;
type InsertUser = InferInsertModel<typeof users>;

import { int, text, sqliteTable } from 'drizzle-orm/sqlite-core';
import { type InferSelectModel, type InferInsertModel } from 'drizzle-orm'

const users = sqliteTable('users', {
  id: int('id').primaryKey(),
  name: text('name').notNull(),
});

type SelectUser = typeof users.$inferSelect;
type InsertUser = typeof users.$inferInsert;
// or
type SelectUser = typeof users._.$inferSelect;
type InsertUser = typeof users._.$inferInsert;
// or
type SelectUser = InferSelectModel<typeof users>;
type InsertUser = InferInsertModel<typeof users>;

import { int, text, singlestoreTable } from 'drizzle-orm/singlestore-core';
import { type InferSelectModel, type InferInsertModel } from 'drizzle-orm'

const users = singlestoreTable('users', {
  id: int('id').primaryKey(),
  name: text('name').notNull(),
});

type SelectUser = typeof users.$inferSelect;
type InsertUser = typeof users.$inferInsert;
// or
type SelectUser = typeof users._.$inferSelect;
type InsertUser = typeof users._.$inferInsert;
// or
type SelectUser = InferSelectModel<typeof users>;
type InsertUser = InferInsertModel<typeof users>;

Logging

To enable default query logging, just pass { logger: true } to the drizzle initialization function:

import { drizzle } from 'drizzle-orm/...'; // driver specific

const db = drizzle({ logger: true });

You can change the logs destination by creating a DefaultLogger instance and providing a custom writer to it:

import { DefaultLogger, LogWriter } from 'drizzle-orm/logger';
import { drizzle } from 'drizzle-orm/...'; // driver specific

class MyLogWriter implements LogWriter {
  write(message: string) {
    // Write to file, stdout, etc.
  }
}

const logger = new DefaultLogger({ writer: new MyLogWriter() });
const db = drizzle({ logger });

You can also create a custom logger:

import { Logger } from 'drizzle-orm/logger';
import { drizzle } from 'drizzle-orm/...'; // driver specific

class MyLogger implements Logger {
  logQuery(query: string, params: unknown[]): void {
    console.log({ query, params });
  }
}

const db = drizzle({ logger: new MyLogger() });

Multi-project schema

Table creator API lets you define customise table names.
It’s very useful when you need to keep schemas of different projects in one database.

PostgreSQL

MySQL

SQLite

SingleStore

import { serial, text, pgTableCreator } from 'drizzle-orm/pg-core';

const pgTable = pgTableCreator((name) => `project1_${name}`);

const users = pgTable('users', {
  id: serial('id').primaryKey(),
  name: text('name').notNull(),
});

import { int, text, mysqlTableCreator } from 'drizzle-orm/mysql-core';

const mysqlTable = mysqlTableCreator((name) => `project1_${name}`);

const users = mysqlTable('users', {
  id: int('id').primaryKey(),
  name: text('name').notNull(),
});

import { int, text, sqliteTableCreator } from 'drizzle-orm/sqlite-core';

const sqliteTable = sqliteTableCreator((name) => `project1_${name}`);

const users = sqliteTable('users', {
  id: int('id').primaryKey(),
  name: text('name').notNull(),
});

import { int, text, singlestoreTableCreator } from 'drizzle-orm/singlestore-core';

const mysqlTable = singlestoreTableCreator((name) => `project1_${name}`);

const users = singlestoreTable('users', {
  id: int('id').primaryKey(),
  name: text('name').notNull(),
});

import { defineConfig } from "drizzle-kit";

export default defineConfig({
  schema: "./src/schema/*",
  out: "./drizzle",
  dialect: "mysql", 
  dbCredentials: {
    url: process.env.DATABASE_URL,
  }
  tablesFilter: ["project1_*"],
});

You can apply multiple or filters:

tablesFilter: ["project1_*", "project2_*"]

Printing SQL query

You can print SQL queries with db instance or by using standalone query builder.

const query = db
  .select({ id: users.id, name: users.name })
  .from(users)
  .groupBy(users.id)
  .toSQL();
// query:
{
  sql: 'select 'id', 'name' from 'users' group by 'users'.'id'',
  params: [],
}

Raw SQL queries execution

If you have some complex queries to execute and drizzle-orm can’t handle them yet, you can use the db.execute method to execute raw parametrized queries.

PostgreSQL

MySQL

SQLite

SingleStore

const statement = sql`select * from ${users} where ${users.id} = ${userId}`;
const res: postgres.RowList<Record<string, unknown>[]> = await db.execute(statement)

import { ..., MySqlQueryResult } from "drizzle-orm/mysql2";

const statement = sql`select * from ${users} where ${users.id} = ${userId}`;
const res: MySqlRawQueryResult = await db.execute(statement);

const statement = sql`select * from ${users} where ${users.id} = ${userId}`;

const res: unknown[] = db.all(statement)
const res: unknown = db.get(statement)
const res: unknown[][] = db.values(statement)
const res: Database.RunResult = db.run(statement)

import { ..., SingleStoreQueryResult } from "drizzle-orm/singlestore";

const statement = sql`select * from ${users} where ${users.id} = ${userId}`;
const res: SingleStoreRawQueryResult = await db.execute(statement);

Standalone query builder

Drizzle ORM provides a standalone query builder that allows you to build queries without creating a database instance and get generated SQL.

PostgreSQL

MySQL

SQLite

SingleStore

import { QueryBuilder } from 'drizzle-orm/pg-core';

const qb = new QueryBuilder();

const query = qb.select().from(users).where(eq(users.name, 'Dan'));
const { sql, params } = query.toSQL();

import { QueryBuilder } from 'drizzle-orm/singlestore-core';

const qb = new QueryBuilder();

const query = qb.select().from(users).where(eq(users.name, 'Dan'));
const { sql, params } = query.toSQL();

Get typed table columns

You can get a typed table columns map, very useful when you need to omit certain columns upon selection.

PostgreSQL

MySQL

SQLite

SingleStore

index.ts

schema.ts

import { getTableColumns } from "drizzle-orm";
import { user } from "./schema";

const { password, role, ...rest } = getTableColumns(user);

await db.select({ ...rest }).from(users);

import { serial, text, pgTable } from "drizzle-orm/pg-core";

export const user = pgTable("user", {
  id: serial("id").primaryKey(),
  name: text("name"),
  email: text("email"),
  password: text("password"),
  role: text("role").$type<"admin" | "customer">(),
});

index.ts

schema.ts

import { getTableColumns } from "drizzle-orm";
import { user } from "./schema";

const { password, role, ...rest } = getTableColumns(user);

await db.select({ ...rest }).from(users);

import { int, text, mysqlTable } from "drizzle-orm/mysql-core";

export const user = mysqlTable("user", {
  id: int("id").primaryKey().autoincrement(),
  name: text("name"),
  email: text("email"),
  password: text("password"),
  role: text("role").$type<"admin" | "customer">(),
});

index.ts

schema.ts

import { getTableColumns } from "drizzle-orm";
import { user } from "./schema";

const { password, role, ...rest } = getTableColumns(user);

await db.select({ ...rest }).from(users);

import { integer, text, sqliteView } from "drizzle-orm/sqlite-core";

export const user = pgTable("user", {
  id: integer("id").primaryKey({ autoIncrement: true }),
  name: text("name"),
  email: text("email"),
  password: text("password"),
  role: text("role").$type<"admin" | "customer">(),
});

index.ts

schema.ts

import { getTableColumns } from "drizzle-orm";
import { user } from "./schema";

const { password, role, ...rest } = getTableColumns(user);

await db.select({ ...rest }).from(users);

import { int, text, mysqlTable } from "drizzle-orm/singlestore-core";

export const user = singlestoreTable("user", {
  id: int("id").primaryKey().autoincrement(),
  name: text("name"),
  email: text("email"),
  password: text("password"),
  role: text("role").$type<"admin" | "customer">(),
});

Get table information

PostgreSQL

MySQL

SQLite

SingleStore

import { getTableConfig, pgTable } from 'drizzle-orm/pg-core';

export const table = pgTable(...);

const {
  columns,
  indexes,
  foreignKeys,
  checks,
  primaryKeys,
  name,
  schema,
} = getTableConfig(table);

import { getTableConfig, mysqlTable } from 'drizzle-orm/mysql-core';

export const table = mysqlTable(...);

const {
  columns,
  indexes,
  foreignKeys,
  checks,
  primaryKeys,
  name,
  schema,
} = getTableConfig(table);

import { getTableConfig, sqliteTable } from 'drizzle-orm/sqlite-core';

export const table = sqliteTable(...);

const {
  columns,
  indexes,
  foreignKeys,
  checks,
  primaryKeys,
  name,
  schema,
} = getTableConfig(table);

import { getTableConfig, mysqlTable } from 'drizzle-orm/singlestore-core';

export const table = singlestoreTable(...);

const {
  columns,
  indexes,
  checks,
  primaryKeys,
  name,
  schema,
} = getTableConfig(table);

Compare objects types (instanceof alternative)

You can check if an object is of a specific Drizzle type using the is() function. You can use it with any available type in Drizzle.

IMPORTANT

You should always use is() instead of instanceof

Few examples

import { Column, is } from 'drizzle-orm';

if (is(value, Column)) {
  // value's type is narrowed to Column
}

Mock Driver

This API is a successor to an undefined drizzle({} as any) API which we’ve used internally in Drizzle tests and rarely recommended to external developers.

We decided to build and expose a proper API, every drizzle driver now has drizzle.mock():

import { drizzle } from "drizzle-orm/node-postgres";

const db = drizzle.mock();

you can provide schema if necessary for types

import { drizzle } from "drizzle-orm/node-postgres";
import * as schema from "./schema"

const db = drizzle.mock({ schema });
