anodb 4.2.1

Convenient Wrapper around AioSQL and a Database Connection

AnoDB

Convenient Wrapper around aiosql and a Database Connection.

Description

This class creates a persistent database connection and imports SQL queries from a file.

If the connection is broken, a new connection is attempted.

Compared do aiosql, the point is not to need to pass a connection as an argument on each call: The DB class embeds both connection and query methods.

Example

Install the module with pip install anodb or whatever method you like. Once available, you can use it:

import anodb
db = anodb.DB('sqlite3', 'test.db', 'test.sql')

db.do_some_insert(key=1, val='hello')
db.do_some_update(key=1, val='world')
print("data", db.do_some_select(key=1))
db.commit()

db.close()

With file test.sql containing something like:

-- name: do_some_select
SELECT * FROM Stuff WHERE key = :key;

-- name: do_some_insert!
INSERT INTO Stuff(key, val) VALUES (:key, :val);

-- name: do_some_update!
UPDATE Stuff SET val = :val WHERE key = :key;
