It correctly identified which tables the procedure writes to, found a table updated three separate times, and spotted a branch that has been unreachable since a parameter default changed. But it couldn't explain a clause that only fires on Tuesdays, whose reason was a promise made to a customer in 2011 by someone who left in 2014. The lesson: AI reads what code does, but only people remember why it does it. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### Can AI explain why an old undocumented SQL stored procedure behaves a certain way? AI can accurately describe what a stored procedure does mechanically, such as which tables it writes to, repeated updates, or dead code branches, but it cannot explain undocumented business reasons behind specific logic. One example involved a clause that only fires on Tuesdays, added in 2011 as an unwritten promise to a customer by an employee who left the company in 2014. _Anyone untangling legacy stored procedures with AI can find more real-world cases like this on daily.dev._ ### What can AI reliably do when analyzing a legacy stored procedure nobody understands? AI can quickly identify what a procedure touches, which tables it writes, where cursors are used, whether the same table is updated multiple times, and whether a code branch has become unreachable due to a changed parameter default. This mechanical analysis, once a careful manual afternoon of work, is described as one of the best current uses of AI in database work. _Developers evaluating where AI genuinely speeds up database maintenance can track examples like this on daily.dev._ ## Similar posts on daily.dev - [AI in Production Without a WHERE Clause](https://daily.dev/posts/ai-in-production-without-a-where-clause-suaczcnj5) · SQL Authority · 135 upvotes · 10 comments - [Nine Unusual Ways My Clients Use AI With SQL Server](https://daily.dev/posts/nine-unusual-ways-my-clients-use-ai-with-sql-server-399rw1ejp) · SQL Authority · 0 upvotes · 0 comments - [I Let AI Write My Code for 7 Days.
