Hola He leído detenidamente tu requerimiento y entiendo que necesitas una solución inmediata para los errores en tus sentencias SELECT Mi enfoque para resolver este problema se basa en tres pilares: 1. Diagnóstico de Errores Identificaré si los problemas provienen de: Sintaxis específica del motor: Diferencias en el manejo de comillas, alias o funciones de fecha. Lógica de Joins: Cruces mal estructurados que generan productos cartesianos o pérdida de datos. Agregaciones: Uso incorrecto de la cláusula GROUP BY o filtros en HAVING. 2. Entrega Técnica Una vez analizado el esquema y los datos de ejemplo, te entregaré: Scripts SQL corregidos: Código limpio, optimizado y con comentarios detallados. Documentación breve: Un resumen por cada consulta explicando el "por qué" del error y la solución aplicada. 3. Garantía de Calidad Aseguraré que los resultados coincidan exactamente con la lógica de negocio que esperas, eliminando los resultados inesperados y mejorando el rendimiento de las consultas. Tengo experiencia avanzada gestionando bases de datos relacionales y me especializo en escribir código SQL legible que otros desarrolladores puedan mantener fácilmente. Quedo a la espera del esquema y las sentencias defectuosas para ponerme manos a la obra de inmediato.

Hello — I’d be glad to help troubleshoot and correct the failing SQL queries in your database. I have strong experience working with MySQL, PostgreSQL, and Oracle, with a particular focus on writing portable, standards-compliant SQL. My approach will ensure your queries not only run correctly in the current environment, but remain compatible across database engines wherever possible. How I’ll Help Review Schema & Sample Data Analyze table structures, constraints, relationships, and indexes Confirm assumptions the original queries rely on Identify Root Causes of Failures Syntax errors or vendor-specific functions Incorrect joins, grouping, or filtering logic Null-handling or type-mismatch issues Ambiguous column references or reserved-keyword conflicts Rewrite Queries to ANSI-SQL Where Feasible Replace engine-specific constructs with portable alternatives Ensure queries run cleanly in MySQL now Note any unavoidable vendor differences (and provide equivalents) Provide Clear Explanations Inline comments in each corrected query If you’re ready, please share the schema, sample data, and problematic queries — I’ll start by reviewing them and provide initial findings promptly. Looking forward to helping you get everything running smoothly. — Akinsola
