如果用户登录失败，则 Python SQL Server 登录重试逻辑

Question

Python SQL Server login retry logic if login failed for user. I am using this logic in a script, but sometimes it's failing to login to the database.

I want to retry to connect to the database if the connection fails.

try:
    cnxn = pyodbc.connect('DRIVER={ODBC Driver 17 for SQL Server};SERVER='+server+';DATABASE='+database+';UID='+username+';PWD='+ password)
    cursor = cnxn.cursor()

Answer 1

with this the connection will be retried until success. do you think there should be limited number of tries?

cursor = None
while cursor is None:
    try:
        
        cnxn = pyodbc.connect('DRIVER={ODBC Driver 17 for SQL Server};SERVER='+server+';DATABASE='+database+';UID='+username+';PWD='+ password)
        cursor = cnxn.cursor()
    except:
         pass
