Usage
- Init a database
from aio_databases import Database
db = Database('sqlite:///:memory:')
- Prepare the database to work
async def my_app_starts():
# Initialize a database's pool
await db.connect()
async def my_app_ends():
# Close pool/connections
await db.disconnect()
# As an alternative users are able to use the database
# as an async context manager
async with db:
await my_main_coroutine()
- Run SQL queries
await db.execute('select $1', '1')
await db.executemany('select $1', '1', '2', '3')
records = await db.fetchall('select (2 * $1) res', 2)
assert records == [(4,)]
record = await db.fetchone('select (2 * $1) res', 2)
assert record == (4,)
assert record['res'] == 4
result = await db.fetchval('select 2 * $1', 2)
assert result == 4
- Use transactions
async with db.transaction() as trans1:
# do some work ...
async with db.transaction() as trans2:
# do some work ...
await trans2.rollback()
