Python Database API Specification v2.0

https://peps.python.org/pep-0249/

import firebirdsql
conn = firebirdsql.connect(
    host='localhost',
    database='/foo/bar.fdb',
    port=3050,
    user='alice',
    password='secret'
)
cur = conn.cursor()
cur.execute("select * from baz")
for c in cur.fetchall():
    print(c)
conn.close()

asyncio

import asyncio
import firebirdsql
async def conn_example():
    conn = await firebirdsql.aio.connect(
        host='localhost',
        database='/foo/bar.fdb',
        port=3050,
        user='alice',
        password='secret'
    )
    cur = conn.cursor()
    await cur.execute("select * from baz")
    print(await cur.fetchall())
asyncio.run(conn_example())

Use pool

import asyncio
import firebirdsql
async def pool_example(loop):
    pool = await firebirdsql.aio.create_pool(
        host='localhost',
        database='/foo/bar.fdb',
        port=3050,
        user='alice',
        password='secret'
        loop=loop,
    )
    async with pool.acquire() as conn:
        async with conn.cursor() as cur:
            await cur.execute("select * from baz")
            print(await cur.fetchall())
    pool.close()
    await pool.wait_closed()
loop = asyncio.get_event_loop()
loop.run_until_complete(pool_example(loop))
loop.close()
