pypyodbc: [Microsoft][ODBC SQL Server Driver][DBNETLIB]ConnectionWrite (send())

Question

My python script reads through around half of the dataset (around 5000 rows out of 10000) and all of a sudden produces this error midway:

[Microsoft][ODBC SQL Server Driver][DBNETLIB]ConnectionWrite (send())

I'm using pypyodbc to connect to the Azure SQL server. I haven't been able to find the solution anywhere online. I don't even know whats the cause that's leading to this error.

Please help.

Answer 1

Hope you are doing well. Have you had a chance to look at pyodbc and pymssql ?
They have a better community presence and are actively maintained. If the script fails with these drivers as well, there might be an issue with your script. I can try to help you troubleshoot if you share it.

Let me know if the issue gets fixed with the other drivers and if it does not I can help you out.

I tried to reproduce the issue, but failed. And I observed that the package last updated in 2013. It's an old and no longer maintenance package for Python ODBC. So I don't recommend to continue to use it to access the latest Azure SQL Database.

I strongly recommended you to use the package pymssql . It's the Azure offical recommend odbc driver for Python, please refer to https://azure.microsoft.com/en-us/documentation/articles/sql-database-libraries/ .

It can very good support any OS environment contains Windows, Linux, MacOS. You can refer to these docs https://azure.microsoft.com/en-us/documentation/articles/sql-database-develop-python-simple-windows/ , https://azure.microsoft.com/en-us/documentation/articles/sql-database-develop-python-simple-ubuntu-linux/ and https://azure.microsoft.com/en-us/documentation/articles/sql-database-develop-python-simple-mac-osx/ to getting started.

If you want to dive into the package usgae, please refer to the offical document http://pymssql.org/en/latest/index.html .

Best Regards.
