SQL Visual Debbuger

What it does

SQL Visual Debugger is a VS Code extension for stepping through supported MySQL SELECT queries clause by clause and inspecting the intermediate result after each stage. It helps explain how data changes through the query instead of only showing the final output.

Extension for Visual Studio Code - Find where your SQL result went wrong. Debug Excel, CSV, SQLite, MySQL, PostgreSQL, and SQL Server in VS Code.

SQL Visual Debugger turns supported SELECT and WITH queries into a step-by-step visual debugger inside VS Code. Instead of only seeing the final result, you can inspect how rows are filtered, joined, grouped, changed, or removed through the query pipeline. Debug SQL the way you debug code: step by step, with the intermediate state visible. SQL bugs are hard because the final result does not show where the problem happened. Was the row removed by WHERE ? Duplicated by a JOIN ? Grouped away by GROUP BY ? Filtered after aggregation by HAVING ? Changed by SELECT , CASE WHEN , or a window function? SQL Visual Debugger shows each stage of the query so you can find the exact step where the result…from marketplace.visualstudio.com

  Visualize SQL Queries2022 · animatesql.com · ▲259

  My co-worker and I were debugging a SQL issue; having not seen SQL in two years, I embarrassed myself by confusing union vs. join. After this episode, I tried refreshing my SQL memory, but there are few websites that animate SQL for you. Most of them just have a series of images to help you visualize. There are a few tools that are quite good and robust (especially for large/complex use cases) but require installation and are too complex for my simple purpose. So, just created a small tool to help visualise SQL. Most of the animations are just my understanding of how SQL works. Would…

  Letting LLMs Run a Debugger2025 · github.com · ▲147

  Hey HN, I just built an experimental VSCode extension called LLM Debugger. It’s a proof-of-concept that lets a large language model take charge of debugging. Instead of only looking at the static code, the LLM also gets to see the live runtime state—actual variable values, function calls, branch decisions, and more. The idea is to give it enough context to help diagnose issues faster and even generate synthetic data from running programs. Here’s what it does: * Active Debugging: It integrates with Node.js debug sessions to gather runtime info (like variable states and stack traces). *…

  Talanoa▲346

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
