I will write and optimize oracle sql and plsql queries, views and procedures
Acerca de este Servicio
Need a SQL query that returns the right numbers, or one that runs too slowly? I will write clean, commented SQL you can trust.
I work every day with Oracle SQL and PL/SQL on large banking data warehouses, where every number must reconcile.
What I can do:
- Complex queries: joins, window functions, CTEs, aggregations
- Optimize slow queries and explain why they were slow
- Views, stored procedures and PL/SQL packages
- Reporting tables and data marts for Power BI or Excel
- Data checks and reconciliation queries
Databases: Oracle, SQL Server, MySQL, PostgreSQL.
You get the .sql file with comments and a short explanation. You can order right away and share your table structure or sample data after ordering. I never need passwords to your production system. I work through Fiverr chat and reply quickly.

FAQ
Do you need access to my database?
No. Table structures and a small sample of data are enough. I never need passwords to your production system.
Can you explain the query?
Yes. Every query comes with comments and a short plain-English explanation of how it works.
Do you help with homework or exams?
No. I only work on real business data and projects.
