FAQ
What SQL databases do you work with?
I primarily work with SQL and Microsoft SQL Server. Please contact me before ordering if you use a different database system.
Can you fix an existing SQL query?
Yes. Send me your current query, the error or problem you are experiencing, and the result you expect.
Can you create queries involving multiple tables?
Yes. I can create queries using JOINs, subqueries, CTEs, aggregations and other advanced SQL techniques.
Can you optimize a slow query?
Yes, depending on the query and the information available about the database structure. Please contact me first for performance-related projects.
Should I contact you before ordering?
For complex queries, multiple tables or custom requirements, I recommend contacting me first so I can confirm the scope and the right package.
