#Install yo azure data studio codeUsing pyodbc, you can easily connect Python applications to data sources with an ODBC driver. In the code cell below, since I know it’s already installed and we have imported it in the cell above, I’ve created both a connection to a SQL Server database named “JimsData” and a SQL command string to query a table named Correlations. Pyodbc is an open-source Python module that makes accessing ODBC (Open Database Connectivity) databases simple. #Install yo azure data studio installIf you are unsure if a module is installed, you can click on Manage packages (shown below) and then view all of the installed packages or, install something new by click Add new: Below, I’ve added a code cell to import the python modules that I want to use later in the notebook (note that I have already installed these libraries into my environment). You add a new code cell by clicking the +Cell command in the toolbar and then selecting Code cell. Notebook code cells allow you to enter and run program code interactively within a notebook. To add a link, you just highlight the desired text and click the link icon, where you can paste in the appropriate URL: Since my audience may not have used notebooks before, I have inserted a reference link to a web page where they can read more information about Azure notebooks. So, for example, in the above image you can see that I’ve added a text cell with a heading and then underneath, an additional note about Azure Notebooks. One of the “cooler things” about notebook text cells is that you can include a reference link within your text. You can select either a rich text, markdown or “split view” (of the cell) to see as you type text, which helps you to get the formatting just right. The cell opens up in “edit mode” so you can type some (markdown) text. Let’s start building this notebook by adding a new text cell by clicking the +Cell command in the toolbar and selecting Text cell. Like GitHub, Azure Data Studio notebooks use markdown language for formatting text cells. Text cells allow you to easily document code in a notebook by adding “Markdown text blocks” in between code cells. You can interleave code and text, but they are separate elements that format in whatever order you’ve placed them. A cell is essentially a section or “step” in a notebook. #Install yo azure data studio seriesNotebooks consist of a series of “cells”. Once you select a kernel and save the notebook, when you reopen the notebook, the associated kernel will be automatically launched and be ready for use. Once you select Python 3, you will need to configure Python for the notebook, by selecting the option to use either an existing Python installation (if Python is already installed) or create a new Python installation (if you select this option, Azure Data Studio will perform the Python installation for you). In this example, we’ll change the kernel to Python 3. By default, the SQL kernel (for executing T-SQL queries for SQL Server) is selected. There are kernels for many languages available, for example the “ipython” kernel (listed as “Python 3”) executes Python code. Once you create a notebook, you’ll need to select a “notebook kernel” for the notebook to “use”.Ī notebook kernel is the “engine” that executes the code you add to the notebook. To create an ADS notebook (from within Azure Data Studio), you simply select File, then New Notebook. You can use ADS notebooks for data cleaning and transformation, numerical simulation, statistical modeling, data visualization, and machine learning (just to name a few). A “Jupyter” Notebook is an open-source web application that lets you create and share documents containing live code, equations, visualizations, and narrative text. Variable correlation can be key to increasing the accuracy of a forecast or predicting potential outcome scenarios.Īzure Notebooks is a Microsoft Azure Platform as a Service (PaaS) offering of Jupyter Notebooks. The objective of this exercise is to demonstrate creating an Azure Data Studio (ADS) Notebook using Python to query SQL Server and investigate correlations between variables.
