Example

The following examples make use of a simple table

CREATE TABLE `users` (
    `id` int(11) NOT NULL AUTO_INCREMENT,
    `email` varchar(255) COLLATE utf8_bin NOT NULL,
    `password` varchar(255) COLLATE utf8_bin NOT NULL,
    PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_bin
AUTO_INCREMENT=1 ;

import trio_mysql.cursors

# Connect to the database
connection = trio_mysql.connect(host='localhost',
                             user='user',
                             password='passwd',
                             db='db',
                             charset='utf8mb4',
                             cursorclass=trio_mysql.cursors.DictCursor)

async with connection as conn:
    async with conn.cursor() as cursor:
        # Create a new record
        sql = "INSERT INTO `users` (`email`, `password`) VALUES (%s, %s)"
        await cursor.execute(sql, ('webmaster@python.org', 'very-secret'))

    # connection is not autocommit by default. So you must commit to save
    # your changes.
    conn.commit()

    # Alternately, you can set up a transaction:
    async with conn.transaction():
        async with conn.cursor() as cursor:
            # Create a new record
            sql = "INSERT INTO `users` (`email`, `password`) VALUES (%s, %s)"
            await cursor.execute(sql, ('webmistress@python.org', 'totally-secret'))

    async with conn.cursor() as cursor:
        # Read a single record
        sql = "SELECT `id`, `password` FROM `users` WHERE `email`=%s"
        await cursor.execute(sql, ('webmaster@python.org',))
        result = await cursor.fetchone()
        print(result)

This example will print:

{'password': 'very-secret', 'id': 1}
