A thread-pooled sqlite3 for asyncio.

SQLitePool

A thread-pooled sqlite3 for asyncio.

Behavior

• stmt.execute() return bool instead of a cursor object:
• True if the query succeeds, or False otherwise
• Empty results on INSERT, UPDATE, DELETE, and SELECT are considered as False

Usage

import asyncio

from sqlitepool import ConnectionPool


async def main():
    pool = ConnectionPool('example.db', size=5)
    await pool.start()

    try:
        stmt = pool.prepare(
            'CREATE TABLE IF NOT EXISTS users ('
            '  id INTEGER PRIMARY KEY,'
            '  name TEXT NOT NULL,'
            '  age INTEGER NOT NULL'
            ');'
        )
        await stmt.execute()

        stmt = pool.prepare('INSERT INTO users (name, age) VALUES (?, ?)')
        await stmt.execute(['Alice', 30])

        stmt = pool.prepare('SELECT * FROM users LIMIT 10')
        await stmt.execute()
        row = await stmt.fetch()

        while row:
            print('*', row['name'], row['age'])
            row = await stmt.fetch()
    finally:
        await pool.shutdown()


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