Connection class

Connection is context manages and must be used with with keyword. Connection returns Query callable object. Query can be called in this ways:

with Connection(**config) as db:
    db.exec("sql query here...")
    db.query(sql query here...")  # query is alias for exec()

# Query is callable and you can also do this:
with Connection(**config) as query:
    query("sql query here...")

Query

Query cannot be called itself, you must use Connection to correctly initialise Query object.

Methods and properties:

• query(), exec(). Execute SQL. There is You can use here this syntax: query('SELECT * FROM users WHERE id = %s', (15,)).
• commit(). Write changes into database.

SELECT

import json

from quicker import Connection


config = {
    'provider': 'mysql',
    'host': '127.0.0.1',
    'port': 3306,
    'user': 'myuser',
    'database': 'mydb',
    'password': 'example',
}

with Connection(**config) as query:
    users = query("SELECT * FROM `users`")

print(json.dumps(users, indent=4))
