How to run python code directly with correct syntax within sequel server management studio 2017


I wrote a python script that takes data from sql via "import pyodbc" The data this scrip pulls is parsed into a text message gateway API to send text messages to customers accordingly. This works fine in python.

However, now I want to write a sql stored procedure that will run every time an new invoice is generated in my business, the send the data for phone number + message through to this python python script within the same sql stored procedure.

The issue I am having right now is writing this python scrip with ssms 2017 and executing it without syntax error. Considering I am using sql 2017 I have enabled python and r respectively.

execute sp_execute_external_script
@language = N'Python',
@script =  N'

import africastalking

username = "sandbox"
apikey = "bf62be6"
africastalking.initialize(username, apikey)
sms = africastalking.SMS
recipients = ["+254797301255"]
message = ["Test from SQL"]
sender = "MegaLtd"

try:
    response = sms.send(message, recipients, sender)
    print(response)
except Exception as e:
    print(f"Houston, we have a problem {e}")

'

This is the error I receive

Solution

  • Your environment most likely uses Python 3.5.2

    https://learn.microsoft.com/en-us/sql/advanced-analytics/r/use-sqlbindr-exe-to-upgrade-an-instance-of-sql-server?view=sql-server-2017

    However, f-strings have been introduced in Python 3.6

    So you either have to somehow upgrade your Python, or just rewrite the exception handling, e.g. like this:

    # ORIG: print(f"Houston, we have a problem {e}")
    print("Houston, we have a problem {}".format(e))
    

    If you're not sure which Python version your environment uses, you could check with

    import sys
    print(sys.version)
