About us
JSSUG is now Jax Data!
Jax Data is a registered non-profit 501c3 charitable organization providing free technical education about the Data Platform surrounding Microsoft SQL Server. This group was founded by Brian Knight in January 2003, creating a community for database developers and administrators in the Jacksonville area. Jax Data aims to educate, share knowledge, best practices, and network. Today, it is a community focusing on data, development, administration, and business intelligence. Free meetings are open to the public on the third Wednesday of every month. Meetings include presentations, technology announcements, local job opportunities, and quick brainstorming/guidance for users experiencing difficulty.

Precon: Advanced T-SQL Triage: The Art of Fixing Terrible Code - Erik Darling
University of North Florida, 1 UNF Dr., Jacksonville, FL, US*****Register here: https://bit.ly/dayofdataprecon2026-1 *****
You’ve seen it before: the procedure that looks like it was generated by an AI trained on Stack Overflow and despair. It’s got MERGE. It’s got RIGHT JOINs. It’s got logic so tangled you’d need a flowchart, a flashlight, and a therapist to debug it. And now… it’s your problem.
In this full-day festival of query-fixing, Erik Darling leads you through the real world mysteries of advanced T-SQL: the strange, the slow, and the occasionally cursed. You’ll tackle tangled paging logic, rescue window functions and indexed views from spools and spills, and finally learn when to keep a CTE and when to yeet it. We’ll refactor data modifications that block like linebackers, decode procedural patterns, and write dynamic SQL that’s powerful and polite.
You’ll learn when to CROSS APPLY, dig into views vs. inline TVFs, and discover why RIGHT JOIN is not simply LEFT JOIN’s syntactic twin. We’ll uncover when user-defined functions wreck your query execution plans—and how to rewrite them with flair. If you’ve ever been curious about why that query sometimes takes SO long and how to best rewrite it without just guessing, this is your playground.
Expect fast demos, big laughs, and a glorious cheat sheet to take home. Because refactoring SQL isn’t just necessary—it’s super fun when you're in the right party.
