This repository contains real-world SQL fixes and query adaptations based on my experience as a Senior Technical Support Analyst. These examples reflect common issues encountered in enterprise environments, including:
- Schema/view mismatches
- Missing columns in SELECT statements
- Business logic integration (discounts, payment types, product gifts)
- JOIN errors and logic corrections
Each script includes comments and context to help others understand the root cause and resolution approach.
- SQL (PostgreSQL, MySQL)
- Database views and schema design
- Real-world business logic scenarios
I'm Julio Arispe, a versatile tech support analyst expanding into Python and data analysis. I specialize in troubleshooting complex systems and translating business needs into technical solutions.
