**aiomysql** is a "driver" for accessing a `MySQL` database

from the asyncio_ (PEP-3156/tulip) framework. It depends on and reuses most

parts of PyMySQL_ . *aiomysql* tries to be like awesome aiopg_ library and

preserve same api, look and feel.

Internally **aiomysql** is copy of PyMySQL, underlying io calls switched

to async, basically ``yield from`` and ``asyncio.coroutine`` added in

proper places)). `sqlalchemy` support ported from aiopg_.

Documentation

-------------

https://aiomysql.readthedocs.io/

Basic Example

-------------

**aiomysql** based on PyMySQL_ , and provides same api, you just need

to use  ``await conn.f()`` or ``yield from conn.f()`` instead of calling

``conn.f()`` for every method.

Properties are unchanged, so ``conn.prop`` is correct as well as

``conn.prop = val``.

.. code:: python

    import asyncio

    import aiomysql

    async def test_example(loop):

        pool = await aiomysql.create_pool(host='127.0.0.1', port=3306,

                                          user='root', password='',

                                          db='mysql', loop=loop)

        async with pool.acquire() as conn:

            async with conn.cursor() as cur:

                await cur.execute("SELECT 42;")

                print(cur.description)

                (r,) = await cur.fetchone()

                assert r == 42

        pool.close()

        await pool.wait_closed()

    loop = asyncio.get_event_loop()

    loop.run_until_complete(test_example(loop))

Example of SQLAlchemy optional integration

------------------------------------------

Sqlalchemy support has been ported from aiopg_ so api should be very familiar

for aiopg_ user.:

.. code:: python

    import asyncio

    import sqlalchemy as sa

    from aiomysql.sa import create_engine

    metadata = sa.MetaData()

    tbl = sa.Table('tbl', metadata,

                   sa.Column('id', sa.Integer, primary_key=True),

                   sa.Column('val', sa.String(255)))

    async def go(loop):

        engine = await create_engine(user='root', db='test_pymysql',

                                     host='127.0.0.1', password='', loop=loop)

        async with engine.acquire() as conn:

            await conn.execute(tbl.insert().values(val='abc'))

            await conn.execute(tbl.insert().values(val='xyz'))

            async for row in conn.execute(tbl.select()):

                print(row.id, row.val)

        engine.close()

        await engine.wait_closed()

    loop = asyncio.get_event_loop()

    loop.run_until_complete(go(loop))
