You will get PostgreSQL, Microsoft SQL Server (T-SQL). SQL Error Debugging.
Project details
Over 10 years of experience, I specialize in high stakes database engineering and advanced relational logic. This project features a multi-platform synchronization strategy, bridging fragmented datasets in T-SQL (SSMS) and PostgreSQL through high-precision joins across four common columns.
Technical Highlights
• Multi-Key Joins: Engineered a robust 4-column matching engine for 100% data alignment.
• Advanced Logic: Utilized CTEs for memory efficiency and COALESCE for null-state validation.
• Expert Debugging: Resolved deep-level "Invalid Object" errors and schema-referencing conflicts.
• Performance: Optimized execution plans to deliver streamlined, production-ready code.
I manage the entire data lifecycle, from resolving Arabic character encoding to building scalable models. This is a validated data architecture built for accuracy.
Stop struggling with slow queries. Purchase this project for optimized SQL scripts that 100% data integrity.
