I will write and fix sql server queries for reports and databases

Need a SQL Server query written, fixed, or explained? I can help.

I write clean, readable T-SQL queries for your database and make sure the results match what you expect.

What I can do:

- Write SELECT queries with JOIN, GROUP BY, subqueries and filters (DQL)

- Insert, update and delete data safely (DML)

- Create and modify tables, views and constraints (DDL)

- Fix queries that return errors or wrong results

- Explain how a query works in simple words

- Prepare queries for reports and ERP data

Database: Microsoft SQL Server

What I need from you:

- Your table structure or sample data

- A clear description of the result you want

- Your SQL Server version

What you get:

- A tested query in a .sql file

- A short explanation of the logic

- Revisions as listed in your package

For bigger tasks, please message me before ordering so I can confirm the scope and give you an accurate offer.

I focus on clear communication and on-time delivery.
