FAQ
Do you need access to my database?
Not always. If you can provide table structure, sample data, and the expected output, I can often write the query without direct database access.
Which databases do you work with?
I can work with PostgreSQL, MySQL, SQLite, and SQL Server. Please message me first for ClickHouse or another specific SQL dialect.
Can you write queries for reports or dashboards?
Yes. I can prepare SQL queries that return structured data for reports, dashboards, spreadsheets, or analysis.
Can you fix an existing SQL query?
Yes, but if the main task is fixing a broken query, my other SQL fix gig may be a better fit.
Can you optimize slow queries?
I can do basic query cleanup and simple improvements. Advanced database performance tuning should be discussed before ordering.
Will you explain the query?
Yes. I can include a short explanation of what the query does and how to use it.
