pyodbc控制台错误消息

Question

如何显示非表返回查询的控制台输出？

例如

Vector row = (Vector) data.elementAt(0);

我在MS SQL Server Management Studio上收到以下错误消息，但不确定如何在带有w / pyodbc的python中看到它。

conn = pyodbc.connect('Driver={SQL Server Native Client 12.0};Server=...')
conn.autocommit = True
cursor = conn.cursor()
sql = """
    ALTER DATABASE XXXX
    SET OFFLINE WITH ROLLBACK IMMEDIATE

    RESTORE DATABASE XXXX
    FROM DISK = '\\path\to\file\XXXX.bak'
"""
cursor.execute(sql)

但是Pyodbc的运行没有引发任何异常，并且很正常。 打印光标对象仅返回光标对象，而Msg 3201, Level 16, State 2, Line 4 Cannot open backup device '\\path\to\file\XXXX.bak'. Operating system error 5(Access is denied.). Msg 3013, Level 16, State 1, Line 4 RESTORE DATABASE is terminating abnormally. 仅适用于结果查询。
