**aiopg** is a library for accessing a PostgreSQL_ database
from the asyncio_ (PEP-3156/tulip) framework. It wraps
asynchronous features of the Psycopg database driver.
Example
-------
.. code:: python
import asyncio
import aiopg
dsn = 'dbname=aiopg user=aiopg password=passwd host=127.0.0.1'
async def go():
pool = await aiopg.create_pool(dsn)
async with pool.acquire() as conn:
async with conn.cursor() as cur:
await cur.execute("SELECT 1")
ret = []
async for row in cur:
ret.append(row)
assert ret == [(1,)]
loop = asyncio.get_event_loop()
loop.run_until_complete(go())
Example of SQLAlchemy optional integration
------------------------------------------
.. code:: python
import asyncio
from aiopg.sa import create_engine
import sqlalchemy as sa
metadata = sa.MetaData()
tbl = sa.Table('tbl', metadata,
sa.Column('id', sa.Integer, primary_key=True),
sa.Column('val', sa.String(255)))
async def create_table(engine):
async with engine.acquire() as conn:
await conn.execute('DROP TABLE IF EXISTS tbl')
await conn.execute('''CREATE TABLE tbl (
id serial PRIMARY KEY,
val varchar(255))''')
async def go():
async with create_engine(user='aiopg',
database='aiopg',
host='127.0.0.1',
password='passwd') as engine:
async with engine.acquire() as conn:
await conn.execute(tbl.insert().values(val='abc'))
async for row in conn.execute(tbl.select()):
print(row.id, row.val)
loop = asyncio.get_event_loop()
loop.run_until_complete(go())
