FAQ
What SQL dialects do you support?
I primarily work with MySQL, PostgreSQL, and SQL Server. If you're using another database (like SQLite, Oracle, or MariaDB), feel free to message me first to confirm compatibility.
What do you need from me to get started?
Please provide: A brief description of the problem or what you're trying to achieve Any relevant SQL queries you're working with The table structures (schemas) involved Sample data or expected output (if available)
Can you work with large or complex databases?
Yes, but depending on the complexity (e.g., many joins, subqueries, or data sources), we may need to arrange a custom offer to ensure proper time and scope.
Do you provide documentation or explanations?
Absolutely! The Premium package includes a support guide that explains how the queries work and where you can modify them in the future. I also provide brief comments in the code across all tiers.
Will you connect to my live database?
For security reasons, I typically do not connect directly to live production systems. Instead, I work with shared queries, schema files, and sample datasets. If a secure connection is required, please message me to discuss options.
Can I request changes after delivery?
Yes. Each package includes a set number of revisions to tweak or clarify the solution. If the scope changes significantly, we can extend the project with a custom offer.
