Veelgestelde vragen
Which database platforms do you work with?
I specialize in Microsoft SQL Server. I can also work with standard SQL that runs on MySQL or PostgreSQL for basic queries.
Do I need to share my database with you?
No. I just need a description of your table structure and the logic you want to achieve. You can share sample data or anonymized examples if helpful.
Can you fix a query that is running slowly?
Yes. Query optimization is one of my core services. Share the query and I will analyze it and deliver an improved version with an explanation of the changes.
