如何捕获特定的pyodbc错误消息

本文介绍了如何捕获特定的pyodbc错误消息的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我尝试了以下代码，

import pyodbc try: pyodbc.connect('DRIVER={%s};SERVER=%s;DATABASE=%s;UID=%s;PWD=%s' % (driver, server, database, uid, password)) except pyodbc.Error, err: logging.warn(err)

我得到的错误消息格式是

The error message format i get is

('HY000', "[HY000] [MySQL][ODBC 5.1 Driver]Access denied for user 'root'@'192.168.2.27' (using password: YES) (1045) (SQLDriverConnect)")

我只想接收错误的消息部分，即

I want to receive just the message part of the error i.e.

Access denied for user 'root'@'192.168.2.27'(using password: YES)

我不知道我是否可以捕获错误，例如找不到驱动程序，主机关闭等.

I dont know if I can catch errors specifically like, driver not found, host down etc..

我也尝试捕获错误，例如:

I also tried catching errors as:

except pyodbc.OperationalError, err: logging.warn(err) except pyodbc.DataError, err: logging.warn(err) except pyodbc.IntegrityError, err: logging.warn(err) except pyodbc.ProgrammingError, err: logging.warn(err) except pyodbc.NotSupportedError, err: logging.warn(err) except pyodbc.DatabaseError, err: logging.warn(err) except pyodbc.Error, err: logging.warn(err)

但是最后一个总是捕获错误.

but the last one always catches the error.

此外，我还看到 pyodbc.Error.message 始终为空. 我如何只获取错误消息.

Fruthermore i saw the pyodbc.Error.message is always empty. How can i get just the message in the error.

谢谢

推荐答案

pyodbc似乎只是包装了基础ODBC实现中的错误/异常，因此您不太可能做到这一点.

pyodbc seems to just wrap the errors/exceptions from the underlying ODBC implementation, so it's unlikely that you will be able to do this.
