Hello everyone, thank you!!
I am trying to make some connections to a Mysql database in asynchronous mode where there is dispute and print on the screen the result that arrives first... but I am not able to make it work...
import asyncio
import aiomysql
loop = asyncio.get_event_loop()
async def test_example():
pool = await aiomysql.create_pool(host='',
port=3306,
user='administrator',
password='',
db='sakila',
loop=loop)
pool2 = await aiomysql.create_pool(host='',
port=3306,
user='administrator',
password='',
db='sakila',
loop=loop)
async with pool2.acquire() as conn2:
async with conn2.cursor() as cur2:
await cur2.execute("SELECT count(*) FROM filme")
print(await cur2.fetchall())
async with pool.acquire() as conn:
async with conn.cursor() as cur:
await cur.execute("SELECT count(*) FROM aluguel")
print(await cur.fetchall())
pool.close()
pool2.close()
await pool.wait_closed()
loop.run_until_complete(test_example())
this was the last code I arrived, trying to make two connections to the bank and 2 queries but the code that is above always arrives first.. Does anyone have any idea how I can make them compete ?
Hello, I don’t know if you have already solved this problem, but if you remove the await when setting the variables pool and pool2, I believe it would solve.
