FAQ
Do you need access to my database?
No. I can work with your SQL queries, table structure and sample data. For advanced cases, I may guide you on how to share execution plans safely.
What do you need to start?
I need your SQL query, a description of the issue (slow performance, errors, etc.), and optionally table structure or sample data.
Can you optimize very large or complex queries?
Yes, but for complex scenarios I recommend contacting me before placing an order so we can define the scope correctly.
Will you modify my database?
No. I provide optimized queries and recommendations. Any changes to your database will always be under your control.
