Thanks for your response Eni, appreciate it.

i did try both % and !
It seems the problem is with the compatibility of pymssql library with the DLT serverless compute specifically , as i am able to install and run import other libraries from pip but not pymssql

From driver logs it appears that the pip install for pymssql succeeds successfully for fails to run the import statement due to some compatibility with the DLT serverless compute runtime 

You may try it in your sample pipeline as well
