The approach is intended to reduce Python object creation and memory overhead during data processing. ### Source excerpt Reviewed by Sumit Sarabhai Fetching a million rows from SQL Server into a Polars DataFrame used to mean a million Python objects, a million GC allocations, and then throwing it all away to build a DataFrame. Not anymore. mssql-python now supports fetching SQL Server data directly as Apache Arrow structures - a faster and more [...] The post Introducing Apache Arrow Support in mssql-python appeared first on Microsoft for Python Developers Blog. ## Write SQL Your Way: Dual Parameter Style Benefits in mssql-python DevFeed: [Write SQL Your Way: Dual Parameter Style Benefits in mssql-python]() Original publisher: [Read original article]() Author: Jahnvi Thakkar Published: 2026-04-07T16:12:05Z Content type: article Language: en Sources: [Microsoft Python Engineering]() Topics: [sql-server](), [Python](), [SQL](), [Microsoft](), [Azure]() Tags: [azure](), [azure-sql](), [client-driver](), [code](), [developers](), [microsoft](), [python](), [python-driver-for-azure-sql](), [python-driver-for-sql-server](), [sql](), [sql-server](), [sql-server-2025]() ### AI overview Microsoft's mssql-python driver now supports both qmark positional parameters and pyformat named parameters for Python applications using SQL Server and Azure SQL. The driver automatically detects the parameter style from the supplied tuple, list, or dictionary, while preserving existing qmark code without configuration changes. ### Source excerpt Reviewed by: Sumit Sarabhai If you've been writing SQL in Python, you already know the debate: positional parameters (?) or named parameters (%(name)s)? Some developers swear by the conciseness of positional. Others prefer the clarity of named. With mssql-python, you no longer need to choose - we support both. We've added dual parameter style support to mssql-python, enabling both qmark and pyformat parameter styles in Python [...] The post Write SQL Your Way: Dual Parameter Style Benefits in mssql-python appeared first on Microsoft for Python Developers Blog. ## Simplifying Resource Management in mssql-python through Context Manager DevFeed: [Simplifying Resource Management in mssql-python through Context Manager]() Original publisher: [Read original article]() Author: Jahnvi Thakkar Published: 2025-09-26T09:49:51Z Content type: tutorial Language: en Sources: [Microsoft Python Engineering]() Topics: [Python](), [sql-server](), [Databases](), [Exception]() Tags: [azure](), [azure-sql](), [cleanup](), [client-driver](), [databases](), [exception-handling](), [python](), [python-driver-for-azure-sql](), [python-driver-for-sql-server](), [sql-server](), [sql-server-2025](), [transactions]() ### AI overview This tutorial explains context manager support in the mssql-python driver for Python applications using SQL Server and Azure SQL. It describes how context managers manage connections and cursors, commit successful transactions, roll back transactions when exceptions occur, and close connections automatically. ### Source excerpt Reviewed by: Sumit Sarabhai and Gaurav Sharma If you've worked with databases in Python, you know the boilerplate: open a connection, create a cursor, run queries, commit or rollback transactions, close cursors and connection. Forgetting just one cleanup step can lead to resource leaks (open connections) or even inconsistent data. That's where context managers step [...] The post Simplifying Resource Management in mssql-python through Context Manager appeared first on Microsoft for Python Developers Blog. ## Understanding WebDriver, Selenium, Marionette, and Browser Automation DevFeed: [Understanding WebDriver, Selenium, Marionette, and Browser Automation]() Original publisher: [Read original article]() Author: Maja Frydrychowicz Published: 2016-07-12T04:00:00Z Content type: article Language: en Sources: [Mozilla Automation]() Topics: [webDriver](), [Browser Automation](), [Selenium](), [Testing](), [Firefox](), [HTTP](), [JSON](), [Mozilla](), [JavaScript](), [Open Source]() Tags: [automation](), [browser](), [browser-ui](), [browsers](), [client-driver](), [firefox](), [foss](), [geckodriver](), [harness](), [http](), [javascript](), [json](), [marionette](), [mozilla](), [open-source](), [payload](), [request](), [responses](), [selenium](), [w3c](), [web](), [webdriver]() ### AI overview An explanatory article untangles the terminology around Marionette, Selenium, WebDriver, FirefoxDriver, and geckodriver. It explains the W3C WebDriver Specification and how its browser-agnostic protocol uses JSON over HTTP to send commands and receive responses for browser automation and testing. ### Source excerpt I define WebDriver, W3C WebDriver, Selenium, geckodriver, FirefoxDriver, Marionette harness/runner/client/driver and more. ## ReactOS Reconsiders Its OpenGL Rendering Backend After Mesa ICD Deprecation DevFeed: [ReactOS Reconsiders Its OpenGL Rendering Backend After Mesa ICD Deprecation]() Original publisher: [Read original article]() Published: 2013-04-11T00:00:00Z Content type: article Language: en Sources: [Front Page on ReactOS Website]() Topics: [ReactOS](), [OpenGL](), [Graphics](), [3D graphics](), [Software](), [client](), [LLVM]() Tags: [3d](), [3d-graphics](), [client-driver](), [deprecated](), [driver](), [free](), [graphics](), [llvm](), [open-source](), [opengl](), [os](), [react](), [reactos](), [win32](), [winapi]() ### AI overview The ReactOS project relied on Mesa for OpenGL 3D graphics, but the Windows installable client driver it used was deprecated after Mesa's shift to Gallium3D. ReactOS evaluated software and LLVM-based rasterizer options, each with performance, completeness, hardware, or build-process limitations. ### Source excerpt OpenGL The ReactOS project has relied on the Mesa Project for OpenGL 3D graphics for a long time, but unfortunately the code needed by ReactOS is no longer maintained by Mesa. Actual rendering involves a chain of components, one of which is the called the installable client driver. The ICD is for the most part bundled with the graphics card driver, though it can also be a driver that performs rendering completely in software.
