About this Gig
Need clean and efficient SQL queries?
I write, fix and optimize SQL queries for SQL Server and Oracle (PL/SQL). Every query comes with clear comments so you can easily understand and reuse it.
What I offer:
- Write SELECT queries with joins, subqueries and CTEs
- Create or fix CREATE, ALTER, INSERT, UPDATE, DELETE and MERGE statements
- Debug queries that give wrong results or errors
- Optimize slow queries
- Schedule queries to run automatically (Premium)
Important:
Please contact me before placing the order. Share your requirements and table structure so we can confirm the exact scope and delivery time. Packages are "up to" the number of queries listed. Very large queries may count as more (I will tell you before you order).
I work only with SQL Server and Oracle. I do not offer NoSQL, server setup or backups.
I focus on accurate, clean and easy-to-understand work. Send me your query and let's get it working!

FAQ
Which databases do you work with?
I work only with SQL Server and Oracle. I write new queries from scratch and also fix existing ones. I do not offer NoSQL, server setup or backups.
What will I receive?
A *.sql script* with clear comments, plus a short explanation of what each query does. For optimization, I also explain what I changed and why.
What should I send you before ordering?
Please send your requirements, table structure (if any), sample data and the result you expect. This helps me confirm the right package and delivery time.
Can you create new tables and write new queries from scratch?
Yes. Tell me what you need, for example a table structure and the queries you want, and I will write them with clear comments.
Will I understand the queries you deliver?
Yes. Every query comes with clear comments and a short explanation so you can reuse and modify it later.
What if my query is very large?
Packages are “up to” the number of queries listed. If a query is very large, I will tell you before you order, so there are no surprises.
Is my data safe?
Yes. Please share only what is needed (sample rows are enough) and remove any sensitive details where possible.
