dm-aiomysql 0.1.3

This is my custom aiomysql client

DM-aiomysql

Urls

• PyPI
• GitHub

* Package contains both asynchronous and synchronous clients

Usage

Run in Windows

If you run async code in Windows, set correct selector

import asyncio
import sys

if sys.platform == "win32":
    asyncio.set_event_loop_policy(asyncio.WindowsSelectorEventLoopPolicy())

Example of using DMAioMysqlClient

Analogue to DMAioMysqlClient is the synchronous client DMMysqlClient.

from dm_aiomysql import DMAioMysqlClient
import asyncio


async def main():
    # create client
    mysql_client = DMAioMysqlClient("localhost", 3306, "username", "password", "database")

    # execute query - results is list[list[Any]]
    list_results = await mysql_client.query("SELECT * FROM users")

    # execute query - results is list[dict[str, Any]
    dict_results = await mysql_client.query("SELECT * FROM users", dict_results=True)

    # execute query with params placeholders
    results = await mysql_client.query("SELECT * FROM users WHEN name = %s", params=["John"])

    # commit data
    await mysql_client.query("UPDATE users SET age = %s WHERE id = %s", params=[25, 2], commit=True)

    # insert data
    data = {"id": 1, "name": "John_1", "age": 21}
    await mysql_client.insert_one("my_table", data)

    # insert many data
    data_list = [{"id": 2, "name": "John_2", "age": 22}, {"id": 3, "name": "John_3", "age": 23}]
    await mysql_client.insert_many("users", data_list)


if __name__ == "__main__":
    asyncio.run(main())

Example of using DMAioEnvMysqlClient

DMAioEnvMysqlClient fully inherits the DMAioMysqlClient class. But the connection parameters are loaded from the ENV variables.

The client will not be created until all ENV variables are set.

Analogue to DMAioEnvMysqlClient is the synchronous client DMEnvMysqlClient.

from dm_aiomysql import DMAioEnvMysqlClient
from dotenv import load_dotenv, find_dotenv

# load ENV variables
load_dotenv(find_dotenv())

# create default client
mysql_client = DMAioEnvMysqlClient()
# needed ENV variables MYSQL_HOST, MYSQL_PORT, MYSQL_USERNAME, MYSQL_PASSWORD, MYSQL_DATABASE

# create custom client
custom_mysql_client = DMAioEnvMysqlClient(env_prefix="PROD_MYSQL")  # by default: env_prefix="MYSQL"
# needed ENV variables PROD_MYSQL_HOST, PROD_MYSQL_PORT, ...

Set custom logger

If you want set up custom logger

from dm_aiomysql import DMAioMysqlClient


# create custom logger
class MyLogger:
    def debug(self, message):
        pass

    def info(self, message):
        pass

    def warning(self, message):
        print(message)

    def error(self, message):
        print(message)


# set up custom logger for all clients
DMAioMysqlClient.set_logger(MyLogger())
