I have a powershell script that I'd like to run as a SQL Agent Job.
It contains 3 lines:
Invoke-SqlCmd...
Copy-Item...
python...
The first 2 lines work flawlessly, however the job fails on the third line in which I call some python.
The powershell script works fine when run manually from the powershell ISE. I assume, and this appears to be the case from some googling that the SQL Agent doesn't like or can't run python on its own, however I would have assumed that since its all part of a powershell script I would get around that problem.
The SQL job error is:
Executed as user: DOMAIN\SQL_ReportServer. A job step received an error at line 3 in a PowerShell script. The corresponding line is 'python StripQuotes.py "E:\DW_Exports\Pearsonvue\CDD.txt"'. Correct the script and reschedule the job. The error information returned by PowerShell is: 'The term 'python' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again. '. Process Exit Code -1. The step failed.
Is there anyway to get this process working?
The term 'python' is not recognized as the name of a cmdlet, function, script file, or operable program.
python is not visible in the PATH for the context of the SQL Server Agent or powershell proxy account. Try invoking python using the fully qualified pathname (e.g. C:\Python37\python.exe). You may encounter further errors which you should then debug as new and separate problems.

I'm trying to execute a python script by SSIS Execute Process Task. The Python script is correct. This script read data from yfinance and do some calculation, then export the calculation data into database. I need to execute this script every day. I make a batch file for execution of script file:
I used SSIS Execute SQL Task and configure properties follow:
But I received this error:
[Execute Process Task] Error: In Executing "D:....\batch_ssis.bat" "" at "", The process exit code was "9009" while the expected was "0".
That exit code 9009 comes from windows, it tries to execute batch_ssis.bat and can't resolve the information contained in the batch file
Make sure you do not have spaces in your path D:.....\ , if you do add quotations to your path so it looks like this "D:......"
Also ensure that python is installed and configured in your PATH windows environment variable so that you can call python from any directory within windows
Set FailTaskIfReturnCodeIsNotSuccessValue to False.
This worked for me today. It ignores whatever exit code the batch script returns.
In my case the expected job runs well but SSIS package failed because of the 9009 exit code returned. I still haven't figured out why.
My Visual Studio Code installation (v.1.59.1) is behaving strangely. Any command I type in the Terminal results in the error "The term 'myCommandHere' is not recognized as the name of a cmdlet, function, script file, or operable program."
This includes but is not limited to variable assignments, as per the above, although non-variable computations work.
I'm new to Python so I often try simple toy bits of code in the terminal to see if they'll work as expected. But since this problem appeared, I cannot use the Terminal for this, and need to run all code as .py scripts (which works fine).
I am on Windows 10, and VS is running with admin rights.
I am trying to run the flopy3_modflow_boundaries example from the FloPy Jupyter Notebook. The notebooks have worked perfectly well for earlier examples (including building, displaying images, running a MODFLOW-NWT model, and viewing the results...so I think have things substantially set up correctly), but for some reason when it gets to the following section of code:
!head -n 10 'data/test.riv'
I get the following error:
'head' is not recognized as an internal or external command,
operable program or batch file.
I'm not sure what the "!head" code with the exclamation mark is supposed to do, or how I can fix the error. If it matters, I'm running Python 3.9 on Windows 7. "Head" is a groundwater term, so I assume it is imported from FloPy in the first step of the notebook?
Thanks!
head is a Unix/Linux shell command to show the first n lines in a file. So running head -n 10 'data/test.riv' would output the first 10 lines in file data/test.riv. Note that when you precede a command with ! in a Jupyter cell, it runs the command as it would in a terminal, and not as Python code.
You can do any of the following:
Run the code on a Unix/Linux machine which has the head command.
Skip the command as it probably will not affect the rest of your code as it is meant to just show you the first 10 lines in the file, which you could just do by opening the file in a text editor.
Replace the command with an alternative command for head in Windows to perform the same function, although AFAIK, there isn't a direct equivalent.
I'm new to programming. Giving this another try.
I've been able to make Python run from PowerShell through changing the Environment variables. When I try to launch Python using Win + R, only py launches python. This puzzles me. PowerShell and cmd have no problem with just typing python.
I'm also trying to make it so that I can launch a python script from anywhere. I made a simple script called again.py in visual studio code and saved the script in a specific folder. When I try to run the script in VSC, I always get the error:
[Running] python -u "c:\Users\xyz\Programming\Python\again.py"
'python' is not recognized as an internal or external command,
operable program or batch file.
[Done] exited with code=1 in 0.137 seconds
By my understanding, if a folder is included in Path, and a file is called that is stored within that folder, the file/script should run. I should be able to call that file from anywhere, but I am just not able to type the file name in PowerShell or Run and have it run.
win + R returns:
Windows cannot find 'again.py'. Make sure you type the name correctly, and try again.
PowerShell: start again.py
start : This command cannot be run due to the error: The system cannot find the file specified.
At line:1 char:1
+ start again.py
+ ~~~~~~~~~~~~~~
+ CategoryInfo : InvalidOperation: (:) [Start-Process], InvalidOperationException
+ FullyQualifiedErrorId : InvalidOperationException,Microsoft.PowerShell.Commands.StartProcessCommand
Typing again.py into cmd causes it to run just fine.
The Powershell error is caused by a space in the file name. Powershell looks at input, start again.py, and parses it like so
first token on row is word "start"
start is an alias to start-process
second token on row is "again.py"
that will be passed as argument to start-process
The easiest work-around is to avoid spaces in file names. Use an underscore or camel case instead. That is, startAgain.py or start_again.py. One can use spaces, but there are extra quoting tricks involved. What's worse, those depend on shell. Cmd has its own rules, Powershell has very different ones. Since you are learning how to program, consider focusing on Python for now and worry later on shell quoting issues.
I am using python 3 on Win10 and running my code by opening a Command Prompt window and typing the file location. However, the window closes as soon as the program terminates, and before I can read any errors.
Edit: This happens whether or not the program has errors.
Thank you.
Solution 1:
I just saw your comment:
When I do that, I recieve the error 'python' is not recognized as an
internal or external command, operable program or batch file
It looks like you haven't specified the path to the python executable: you need to add the python executable path to your Window's PATH variable. You can see how to do that here: Add Python to the PATH Environmental Variable (‘python’ is not recognized as an internal or external command)
Solution 2:
You can use input("enter to exit") at the end of your python code to keep the program alive. It would exit once you press enter.
You could also surround your code in a try except statement and place thr input() in the except to prevent the program from exiting when there are errors, but like #Kevin mentioned in the comments, this would catch run time errors but not syntax errors.
Solution 3:
You can write errors or anything information you want to a file such as log.txt for example, and then read that log file once the code finishes running e.g. how to write to a file in Python
FWIW, I have several Python versions on my Windows system, so I don't want to add any Python directories to my path permanently.
Code for each version is in a separate folder (e.g. 'py37'), with a subfolder for each project e.g. 'myProject'.
In py37, there's a batch file called pyEnv.bat with this content:
#echo off
path=%path%;C:\Python37\;C:\Python37\Scripts\
cd.
cmd
In Windows explorer, I head over to the project folder I want to work in, click in the address bar and type ..\pyEnv. That launches a DOS-box, in which I now can do python myproject.py. You can see print() output, errors, and so on.
You can up-arrow to try different modules, having typed them first.
Once you quit the DOS-box, your path is back to normal again.
