Hi @Prashant2 I am curious to know how you installed the library in your notebook. Did you use

%pip install pymssql

If so, could you try using a shell command instead, like:

!pip install pymssql

I’ve had success using !pip install in serverless compute environments + dlt serverless jobs. For example, I recently installed weasyprint this way and was able to use it in a UDF for my final Delta Live Table.

Let me know if that works for you!
