Why does this SQL lock table block readers?
Why does this SQL lock table block readers in production. The SQL code runs a long update in a transaction, holding locks and blocking reads. In SQL services this causes latency spikes and timeouts.

Why does this SQL cache leak across tenants?
Why does this SQL cache leak across tenants in production. The SQL layer caches results without a tenant key, so one tenant sees another tenant's data. In SQL multi tenant apps this is a privacy incident.

What's wrong with this SQL hmac check?
What's wrong with this SQL HMAC check in a webhook table. The SQL code compares signatures with a non constant time check in application logic. In SQL backed services this allows timing attacks.

What's wrong with this SQL file import?
What's wrong with this SQL file import job. The SQL code loads a CSV with the wrong delimiter and silently shifts columns. In SQL pipelines this corrupts data without errors.

Why does this SQL join explode rows?
Why does this SQL join explode rows in production. The SQL code joins two tables without a proper predicate, causing a cartesian explosion. In SQL services this creates massive duplicates and outages.

What's wrong with this SQL pagination?
What's wrong with this SQL pagination in a busy table. The SQL code uses OFFSET while new rows are inserted, so items shift and get skipped. In SQL APIs this causes missing and duplicated results.

Why does this SQL retry charge customers twice?
Why does this SQL retry logic charge customers twice in production. The SQL code inserts a charge record on retry without an idempotency key, so the gateway processes duplicates. In SQL billing systems this creates double charges and refunds.
