FAQ
What do you need from me to start the SQL work?
I need your database schema (table names + columns) and a clear description of what you want to analyze. A sample dataset is always helpful.
Do you need access to my database?
Not always. In most cases, you can share a schema or sample data. If live access is required, read-only access is enough.
What kind of SQL tasks do you handle?
Data extraction, joins, aggregations, KPI calculations, optimization of slow queries, and preparing data for dashboards like Power BI.
Can you work with PostgreSQL or MySQL specifically?
Yes. I work with PostgreSQL and MySQL regularly. If your SQL dialect is slightly different, I’ll adapt the queries.
Will you explain the SQL queries after delivery?
Yes. My SQL is clean and readable, and I can explain how the logic works if needed.
Should I message you before placing an order?
Yes. SQL tasks vary in complexity. Messaging first ensures correct pricing and avoids delays.
