[Microsoft] [用于SQL Server的ODBC驱动程序17]登录超时已过期（0）（SQLDriverConnect）'）

Question

I am unable to make a connection to the SQL server from Unix using python.

I will not be able to replace the driver from ODBC Driver 17 for SQL Server to ODBC Driver 13 for SQL Server as explained in Pyodbc: Login Timeout Error due to other dependencies.

Can somebody please suggest an alternative?

CODE:

import sqlalchemy as sa

from urllib import parse as db_parse

from sqlalchemy import event

params = db_parse.quote_plus(r"DRIVER={ODBC Driver 17 for SQL Server};SERVER='server,port';DATABASE=DB_NAME;username=USER_ID;password=PWD;Trusted_Connection=yes")

engine = sa.create_engine('mssql+pyodbc:///?odbc_connect={}'.format(params))

connection = engine.connect()

ERROR:

sqlalchemy.exc.OperationalError: (pyodbc.OperationalError) ('HYT00', '[HYT00] [Microsoft][ODBC Driver 17 for SQL Server]Login timeout expired (0) (SQLDriverConnect)') (Background on this error at: http://sqlalche.me/e/e3q8)

Answer 1

My connection string looks different:

"DRIVER={ODBC Driver 17 for SQL Server};SERVER=myserver;DATABASE=mydb;UID=myuser;PWD=mypassword"

leeds to

import pyodbc
connection = pyodbc.connect("DRIVER={ODBC Driver 17 for SQL Server};SERVER=myserver;DATABASE=mydb;UID=myuser;PWD=mypassword", autocommit=True)

Instead of UID you are using username, etc. All words starting with 'my' have to be replaced with the actual db, user and password. You should also remove the Trusted_Connection=True; part as Panagiotis Kanavos pointed out in the comment. This says you are using your windows-user to authenticate (which is obviously not available on linux).
