FAQ
What SQL databases do you work with?
I can help with PostgreSQL, MySQL, SQLite, and standard SQL logic. If you use another database, please contact me before ordering.
Can you fix a query that returns wrong results?
Yes. Please send the query, table structure, sample data if possible, the error message, and the expected result.
Do you need access to my database?
Not always. In many cases I can work with the query, table schema, sample rows, screenshots, or exported data. Please do not send passwords or sensitive credentials.
Can you explain the SQL query?
Yes. I can include a short explanation of the query logic, joins, filters, and output, depending on the selected package or add-on.
Do you optimize slow SQL queries?
I can help with basic query improvement. For complex performance tuning, large databases, indexing strategy, or server-level optimization, please contact me before ordering.
