### Initializing DB0 with better-sqlite3 Connector (JavaScript)

Source: https://github.com/unjs/db0/blob/main/docs/2.connectors/sqlite.md

This example shows how to initialize a DB0 database instance using the `better-sqlite3` connector. This connector requires the `better-sqlite3` npm package to be installed as a prerequisite. It configures an in-memory database by passing `name: ':memory:'` to the connector.

```JavaScript
import { createDatabase } from "db0";
import sqlite from "db0/connectors/better-sqlite3";

const db = createDatabase(
  sqlite({
    name: ":memory:",
  }),
);
```

### Connecting to SQLite and Performing Basic CRUD Operations with db0

Source: https://github.com/unjs/db0/blob/main/docs/1.guide/1.index.md

This snippet demonstrates how to initialize db0 with a SQLite connector, create a 'users' table, insert a new user record, and query for users. It also illustrates the use of static parameters for table names, emphasizing the security warning against using untrusted sources for such parameters as they are not sanitized.

```TypeScript
import { createDatabase } from "db0";
import sqlite from "db0/connectors/better-sqlite3";

// Initiate database with SQLite connector
const db = createDatabase(sqlite({}));

// Create users table
await db.sql`CREATE TABLE IF NOT EXISTS users ("id" TEXT PRIMARY KEY, "firstName" TEXT, "lastName" TEXT, "email" TEXT)`;

// Add a new user
const userId = "1001";
await db.sql`INSERT INTO users VALUES (${userId}, 'John', 'Doe', '')`;

// Query for users
const { rows } = await db.sql`SELECT * FROM users WHERE id = ${userId}`;
console.log(rows);

// Using static parameters
const tableName = "users";
const { rows } =
  await db.sql`SELECT * FROM {${tableName}} WHERE id = ${userId}`;
console.log(rows);
```

### Integrating DB0 with Drizzle ORM in TypeScript

Source: https://github.com/unjs/db0/blob/main/docs/3.integrations/drizzle.md

This snippet demonstrates how to initialize a DB0 database instance using the `better-sqlite3` connector, perform basic SQL operations with the `db.sql` API (creating a table and inserting data), and then integrate with Drizzle ORM to leverage its typed API for more advanced queries like selecting all users. It highlights the seamless transition between DB0's simple API and Drizzle's powerful ORM capabilities.

```TypeScript
import { createDatabase } from "db0";
import sqlite from "db0/connectors/better-sqlite3";
import { drizzle } from "db0/integrations/drizzle";
import { sqliteTable, text, numeric } from "drizzle-orm/sqlite-core";

// Initialize DB instance
// You can use any other available connector
const db = createDatabase(sqlite({}));

// Use simple db0 API to make queries
await db.sql`create table if not exists users (
    id integer primary key autoincrement,
    full_name text
  )`;
await db.sql`insert into users (full_name) values ('John Doe')`;

// And then leverage drizzle typed API to make more advanced ones
const drizzleDb = drizzle(db);
await drizzleDb.select().from(users).all();
```
