🌐 The Verdú Method

Native Cross-Database Queries in Firebird 2.5 Using EXECUTE STATEMENT ON EXTERNAL

"Una técnica que conecta España con China… sin APIs, sin replicación, solo con SQL puro."

This repository documents a groundbreaking technique discovered by Salvador Verdú in 2023, enabling real-time queries across multiple Firebird 2.5 databases —even across continents— using only native SQL features.

✅ No external libraries
✅ No UDFs, no ETL, no scripts
✅ Works with remote databases over TCP/IP
✅ Full error handling and scalability


🔍 ¿Qué es el Método Verdú?

Es una técnica que aprovecha una funcionalidad no documentada pero operativa en Firebird 2.5:

EXECUTE STATEMENT 'SELECT ...' 
  ON EXTERNAL '114.22.xxx.xxx:C:\ruta\base.fdb'
  AS USER 'SYSDBA' PASSWORD 'masterkey'
  INTO :var1, :var2;
