FAQ
Can you fix SQL syntax errors?
Yes. I can fix common SQL syntax errors and help make the query run correctly.
Can you fix wrong report results?
Yes. I can review joins, filters, grouping, and aggregation logic to find why the report result looks wrong.
Do you need access to my database?
Not always. If you can provide the query, table structure, sample data, and expected result, I can often work without direct database access.
Which SQL databases do you work with?
I can work with common SQL syntax for PostgreSQL, MySQL, SQLite, and SQL Server. Please message me first for ClickHouse or other specific SQL dialects.
Can you optimize slow SQL queries?
I can help with basic query cleanup and simple performance improvements. Complex database performance tuning should be discussed before ordering.
Will you explain the fix?
Yes. I can include a short explanation of what was changed and why.
