如何使python在pyodbc上退出超時錯誤？

Question

當數據庫拋出超時錯誤時，如何讓我的python腳本退出？我只得到了消息，如果我CTRL-C手動退出 - 我想獲得蟒蛇立即停止在錯誤 ..

#!/usr/bin/python 
import pyodbc 
conn = pyodbc.connect("DSN=OurDSN", autocommit=True) 
cursor = conn.cursor() 
query = "SELECT * FROM our_table limit 100" 
for row in cursor.execute(query): 
    print row 

錯誤消息：

"Traceback (most recent call last):   
File "./impala_test.py", line 6, in <module> 
conn = pyodbc.connect("OurDSN=Hive", autocommit=True) 
pyodbc.Error: ('HY000', '[HY000] [unixODBC][Cloudera][HiveODBC] (34) Error from Hive: EAGAIN (timed out). (34) (SQLDriverConnect)')"

pyodbc的query timeout在默認情況下被禁用。嘗試將其設置爲您想要的值？
