如何在sequel server management studio 2017中使用正确的语法直接运行python代码

Question

我写了一个python脚本，通过"import pyodbc“从sql获取数据，这个脚本提取的数据被解析成文本消息网关API，从而相应地向客户发送文本消息。这在python中工作得很好。

但是，现在我想编写一个sql存储过程，它将在我的业务中每次生成新发票时运行，将电话号码+消息的数据发送到同一sql存储过程中的python python脚本。

我现在遇到的问题是用ssms 2017编写这个python脚本，并在没有语法错误的情况下执行它。考虑到我使用的是sql 2017，我已经分别启用了python和r。

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}")

'

这是我收到的错误

您的环境很可能使用Python 3.5.2

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

但是，在Python 3.6中引入了f字符串

所以你要么升级你的Python，要么重写异常处理，例如：

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

如果您不确定环境使用的是哪个Python版本，可以查看

import sys
print(sys.version)
