"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
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;
