Aunque esto no es posible con cualquier base de datos. Dependiendo de la base y las componentes que se usen, a veces RecNo simplemente devuelve -1

Segun el Help:

As implemented in TDataSet, the value of RecNo is always -1. Ordinarily an application does not access RecNo at the TDataSet level. Instead a redeclared and implemented RecNo property in a descendant class such as TTable is accessed. RecNo provides a fallback property for derived datasets that do not support record numbers.
