Installing Msodbcsql in Azure Databricks
Installing the Microsoft ODBC Driver for SQL Server (msodbcsql) in Azure Databricks involves a series of steps that allow you to connect to Azure SQL databases from your Databricks environment. Here’s how you can do it:
- Install pyodbc Library: First, ensure that the pyodbc library is installed in your Databricks cluster. You can install it using the following command in a Databricks notebook:
dbutils.library.installPyPI("pyodbc") - Install Msodbcsql Driver: You need to install the msodbcsql driver on the Databricks cluster nodes. This can be done using shell commands. Here’s an example for Ubuntu-based systems:
%sh curl https://packages.microsoft.com/keys/microsoft.asc | apt-key add - curl https://packages.microsoft.com/config/ubuntu/16.04/prod.list > /etc/apt/sources.list.d/mssql-release.list apt-get update ACCEPT_EULA=Y apt-get install msodbcsql17 - Verify Installation: After installation, verify that the driver is correctly installed by checking the list of installed packages or running a test query using pyodbc.
