Need help writing, fixing, or improving an SQL query?

I am a software engineer with professional experience in software development, SQL, database investigation, debugging, and technical support.

I can help you with:

  • Writing SQL queries based on your requirements
  • Fixing errors in existing SQL queries
  • SELECT, INSERT, UPDATE, and DELETE queries
  • JOINs, filtering, sorting, and grouping
  • Subqueries and aggregate queries
  • Improving and optimizing existing queries
  • Troubleshooting unexpected query results
  • Explaining queries and their logic

I focus on understanding your requirement first and providing a clear, practical solution rather than simply sending code.

Before ordering:

Please contact me first if your task involves a complex database, stored procedures, large datasets, performance investigation, database design, or production-system access. This will allow me to understand the scope and recommend the appropriate package.

Please feel free to message me if you are unsure which package is suitable for your task.
