FAQ
What if the query doesn't work on my database?
I'll fix it for free. Just send me the error message and I'll debug and rewrite until it runs correctly on your system.
Can you write queries for very large tables with millions of rows?
Yes. For large tables I'll also write queries with performance in mind — using proper indexing hints, avoiding full scans, and using efficient JOIN strategies.
Can you explain the query so I understand it?
Absolutely. Every query I deliver includes inline comments explaining what each section does. I can also send a short written explanation separately if needed.
