A satirical, nostalgic look back at the long-removed T-SQL Debugger that once shipped with SQL Server, paired with Profiler and a physical jog/shuttle hardware console attached via PS/2 ports. The piece humorously walks through how the debugger worked (Mark In/Mark Out, play/pause/rewind controls, variable inspection) and explains, tongue-in-cheek, why it disappeared: databases moved into locked data centers, the debugger caused server-wide freezes via the PREEMPTIVE_DEBUG wait type, and Azure SQL DB never got the system-level permissions needed to support it. It closes with a jab at Microsoft adding ads to SSMS and at pricey AI hardware gadgets.

Why was the T-SQL debugger removed from SQL Server Management Studio?
It was removed because databases moved from local desks into locked, remote data centers making the old hardware console impractical, because stepping through code froze the entire server for other users via the PREEMPTIVE_DEBUG wait type, and because Azure SQL DB never received the system-level permissions the debugger required, so Microsoft dropped it to keep one consistent tool across all database products.
