Question

我试着检索运行

import pymssql 
conn = pymssql.connect(server='IP', user='domain\user', password='PSWD', tds_version='8.0') 
cursor = conn.cursor() 
cursor.execute("EXEC msdb.dbo.sp_start_job @job_name = 'jobname'") 

结果表单时，它的任务添加到提示来处理它不会返回任何东西，但是当作业未拼命地跑，将返回这样的东西在进行测试的情况下

Traceback (most recent call last): 
    File "shared/python3", line 85, in <module> 
    cursor.execute("EXEC msdb.dbo.sp_start_job @job_name = ''") 
    File "pymssql.pyx", line 467, in pymssql.Cursor.execute (pymssql.c:7533) 
pymssql.OperationalError: (14262, "The specified @job_name ('') does not exist.DB-Lib error message 14262, severity 16:\nGeneral SQL Server error: Check messages from the SQL Server\n") 

在这种情况下，错误指出Job_name不存在。我想要做的就是把结果上，我可以收杆进行差错控制...

我已经试过这样的字符串变量是什么：

import sys 

# Store the reference, in case you want to show things again in standard output 
old_stdout = sys.stdout 

# This variable will store everything that is sent to the standard output 
result = StringIO() 
sys.stdout = result 

# Here we can call anything we like, like external modules, and everything that they will send to standard output will be stored on "result" 
cursor.execute("EXEC msdb.dbo.sp_start_job @job_name = 'jobname'") 

# Redirect again the std output to screen 
sys.stdout = old_stdout 

# Then, get the stdout like a string and process it! 
result_string = result.getvalue() 
process_string(result_string) 

link。但无法让它工作。

您正在看到回溯，因为您没有处理在作业名称不存在时发生的异常。如果您想捕获错误消息，则可以简单地捕获该异常。作为一个通用的例子，而不是仅仅做

crsr.execute(sql) 

你可以做

try: 
    crsr.execute(sql) 
except Exception as e: 
    (error_code, error_message) = e 

，然后使用error_code和error_message值，并写入到一个日志文件，或将它们吐出到控制台，或其他。
