FAQ
What do I need to share with you?
Just your table structure (schema or CREATE TABLE statements) and a clear description of what you need the query to do. A sample of your data helps too but isn't required.
Which databases do you support?
I work with MySQL, PostgreSQL, SQLite, and MS SQL Server. If you're using a different database, message me first and I'll let you know if I can help.
Can you fix a query I already wrote?
Yes. Share the query and the error or wrong output you're getting — I'll diagnose and fix it, and explain what was wrong.
What if I'm not happy with the result?
Basic package includes 2 revisions, Standard includes 3, and Premium includes unlimited revisions. Additional revision rounds can be purchased as an extra. I won't close an order until the delivery is accurate and meets your requirements.
Do you offer Python + MySQL integration?
Yes. I can write Python scripts that connect to your MySQL database and perform operations like inserting, fetching, updating, and deleting records. Share what you need and I'll let you know if it fits your package.
