turso> INSERT INTO users VALUES (1, 'alice');
turso> INSERT INTO users VALUES (2, 'bob');
turso> SELECT * FROM users;
1|alice
2|bob

Rust Installation

To use Turso with Rust, add it to your project with:

cargo add turso

Then, you can connect to a database and execute queries as follows:

let db = Builder::new_local("sqlite.db").build().await?
let conn = db.connect()?;

let res = conn.query("SELECT * FROM users", ()).await?

JavaScript Installation

For JavaScript projects, you can install Turso with npm:

npm i @tursodatabase/database

Here's an example of how to use Turso in a JavaScript project:

import { connect } from '@tursodatabase/database';

const db = await connect('sqlite.db');
const stmt = db.prepare('SELECT * FROM users');
const users = stmt.all();
console.log(users);

Python Installation

To use Turso with Python, install the pyturso package:

uv pip install pyturso

Here's an example of how to use Turso in a Python project:

import turso

con = turso.connect("sqlite.db")
cur = con.cursor()
res = cur.execute("SELECT * FROM users")
print(res.fetchone())

Go Installation

For Go projects, you can install Turso with:

go get turso.tech/database/tursogo
go install turso.tech/database/tursogo

Here's an example of how to use Turso in a Go project:

import (
    "database/sql"
    _ "turso.tech/database/tursogo"
)

conn, _ = sql.Open("turso", "sqlite.db")
defer conn.Close()

stmt, _ := conn.Prepare("select * from users")
defer stmt.Close()

rows, _ = stmt.Query()
for rows.Next() {
    var id int
    var username string
    _ := rows.Scan(&id, &username)
    fmt.Printf("User: ID: %d, Username: %s\n", id, username)
}

REAL Code Examples from the Repository

Let's dive into some real code examples from the Turso repository to see how it works in practice.

Example 1: Creating and Querying a Table

Here's a basic example of creating a table and querying it using the Turso command line interface:

turso> CREATE TABLE users (id INT, username TEXT);
turso> INSERT INTO users VALUES (1, 'alice');
turso> INSERT INTO users VALUES (2, 'bob');
turso> SELECT * FROM users;
1|alice
2|bob

This example demonstrates the basic workflow of creating a table, inserting data, and querying the data. The SQL syntax is familiar to anyone who has worked with SQLite, making it easy to get started.

Example 2: Using Turso with Rust

Here's an example of how to use Turso in a Rust project:

use turso::Builder;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let db = Builder::new_local("sqlite.db").build().await?
    let conn = db.connect()?;

    let res = conn.query("SELECT * FROM users", ()).await?
    println!("{:?}", res);

    Ok(())
}

In this example, we use the Builder to create a new local database connection. We then query the users table and print the results. The query method returns a result set that can be printed or processed further.

Example 3: Using Turso with JavaScript

Here's an example of how to use Turso in a JavaScript project:

import { connect } from '@tursodatabase/database';

async function main() {
    const db = await connect('sqlite.db');
    const stmt = db.prepare('SELECT * FROM users');
    const users = stmt.all();
    console.log(users);
}

main().catch(console.error);

In this example, we use the connect function to establish a connection to the database. We then prepare a SQL statement and execute it to retrieve all users. The results are logged to the console.

Example 4: Using Turso with Python

Here's an example of how to use Turso in a Python project:

import turso

con = turso.connect("sqlite.db")
cur = con.cursor()
res = cur.execute("SELECT * FROM users")
print(res.fetchone())

In this example, we use the connect function to establish a connection to the database. We then create a cursor and execute a SQL query to retrieve the first user. The result is printed to the console.
