mysql-context-manager 0.1.5

Work with MySQL databases asynchronously, and in context.

MySQL Context Manager

Work with MySQL based databases asynchronously, using a context manager.

Getting started

You can get mysql-context-manager from PyPI, which means you can install it with pip easily:

python -m pip install mysql-context-manager

Example

from mysql_context_manager import MysqlConnector

async with MysqlConnector(hostname="localhost") as conn:
    results = await conn.query("select username from users where is_bender = 1 order by username asc;")
assert results[0]["username"] == "Aang"
assert results[1]["username"] == "Katara"
assert results[2]["username"] == "Toph"

Example using SQLAlchemy

from mysql_context_manager import MysqlConnector
import sqlalchemy
from sqlalchemy.dialects import mysql

metadata = sqlalchemy.MetaData()

users = sqlalchemy.Table(
    "users",
    metadata,
    sqlalchemy.Column("user_id", mysql.INTEGER(), autoincrement=True, nullable=False),
    sqlalchemy.Column("username", mysql.VARCHAR(length=128), nullable=False),
    sqlalchemy.Column("is_bender", mysql.SMALLINT(), autoincrement=False, nullable=True),
    sqlalchemy.PrimaryKeyConstraint("user_id"),
    mysql_default_charset="utf8mb4",
    mysql_engine="InnoDB",
)

async with MysqlConnector(hostname="localhost") as conn:
    results = await conn.query(users.select().where(users.c.username == "Aang"))
assert results[0]["username"] == "Aang"
assert results[0]["is_bender"] == 1
