Best to do further reading into the functions you're using to make this decision. Some functions already handle parallelization, and in these cases this parameter should stay at the defualt zero. = Enables parallel execution of scripts.This must be of type pandas* DataFrame (or pandas Series, naturally). = Whatever the name of the variable in the Python script which contains the data you'd like to be returned to SQL Server.

= The name you want to give the dataset which is used inside the Python script.= T-SQL query that specifies the input data.

Even if the stored proc parameter is indented, you must write the script as you would in your preferred Python IDE (i.e. push the code all the way to the left with correct indentations). Be careful! Indentations are important in Python. Although I'll explain the parameters here in my own words and include any comments I think are worth knowing: The official details of this stored procedure can be found through the link I've posted at the bottom of this page. The stored procedure and its parameters look like this: The Python integration is enabled by the 'sp_execute_external_script' stored procedure, which is enabled as part of the installation & configuration process detailed in the link above. Instead, I'll just point you to the Microsoft docs. I shan't go through the installation and set-up of the Machine Learning Services feature, because it has already been done elsewhere. In this blog I will provide a few, simple examples which make use of this capability to carry out some simple Python commands. So any application that can speak to SQL Server can invoke the Python code and retrieve the results. So no more clunky data transferring! To address the second point – operationalizing a Python model/script is as easy as calling a stored procedure. So the huge benefit is the ability to stay within your preferred IDE, connect to a SQL Server instance and do the computations on the SQL Server Machine.

Achieve enterprise grade performance and scale (much faster mechanism than ODBC).

Easily operationalize Python code inside SQL.Eliminate data movement (having to transfer data samples from a database to a Python IDE using local compute resources).The main benefits from this are the abilities to: This capability was announced early last year, with the corresponding integration with R already being possible for a number of months. Before Christmas I played around with SQL Server 2017's inline Python integration capability.
