**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))
