Snippets for tests:
SELECT toTimeZone(now(), 'UTC')
SELECT toTimeZone(now(), 'EST')
SELECT toTimeZone(now(), 'Europe/Moscow')
This also works, but it could be reconsidered as a bug in Clickhouse and therefore be changed in future releases:
SELECT toStartOfDay(now())
Python 3.9 has native support for timezones (module zoneinfo
) and there is backports.zoneinfo
.
Using password with "/" (e.g. "6p_/D!h") raise ValueError
Function urlsplit
in the dsn_to_params
function parse parameter dns
(url string) by delim by slash and spoil password
I'd had exception: ValueError: Port could not be cast to integer value as '6p_'
I propose use function connect keyword args for hard password with slash. For example:
aiochsa.connect("clickhouse://localhost:8123/default", user="admin", password="6p_/D!h")
At current implementation using keywords "user" and "password" on create pool is useless, because it will be override at line 58 pool.py
params.update(dsn_to_params(dsn))
I wanna delete all rows from my table, but I'd have exception sqlalchemy.exc.CompileError: WHERE clause is required
My code:
await test_db.execute(electricity_battery.delete())
I cannot type a new connection object, because Pool may not be imported
db_conn: Optional["Pool"] = None
Python and MyPy point to that
Mypy: Name "Pool" is not defined
Unresolved reference 'Pool'
Need to add Pool to import at __init__.py
from .pool import connect, create_pool, Pool
