FAQ
Do I need to provide access to my SQL Server database?
Not always. For query development or troubleshooting, you can provide the table structure, sample data, existing SQL code, and expected results. Remote or database access may be required for more complex optimization or troubleshooting.
Can you work with an existing SQL Server database?
Yes. I can analyze and modify existing databases, queries, stored procedures, views, functions, triggers, and reports without requiring a database to be built from scratch.
Can you optimize slow SQL queries?
Yes. I can analyze slow queries, JOINs, execution logic, indexes, filters, and database structure to identify performance issues and recommend or implement improvements.
Can you create stored procedures, views, triggers, and functions?
Yes. I can develop or troubleshoot stored procedures, views, functions, triggers, CTEs, complex JOINs, subqueries, and other Microsoft SQL Server objects.
Do you work with ERP or business databases?
Yes. I have experience working with complex ERP and business databases involving accounting, purchasing, inventory, projects, financial reporting, and multi-company environments.
Should I contact you before placing an order?
For simple SQL tasks, you can order directly. For complex databases, integrations, performance issues, multiple requirements, or ERP-related work, please contact me first so I can recommend the appropriate package.
