[postgis-users] Tabla con diferencias (Table with differences)

[Néstor Ramires]

Using this statement I get the 28 records in the table mineral_ln that if they are "duplicated" in the table Forestal_ln

SELECT mineral_ln.id FROM mineral_ln, forestal_ln WHERE ST_Contains(mineral_ln.geometria, forestal_ln.geometria);

What would you have to modify in the query to get the three records (ID: 20, 25, 27 of the MINERAL_LN table) that do not appear in those 28 records?


Utilizando esta sentencia obtengo los 28 registros de la tabla mineral_ln que si están "duplicados" en la tabla forestal_ln

SELECT mineral_ln.id FROM mineral_ln, forestal_ln WHERE ST_Contains(mineral_ln.geometria, forestal_ln.geometria);

¿Qué tendría que modificar en la consulta para obtener los tres registros (id: 20, 25, 27 de la tabla mineral_ln) que no aparecen en esos 28 registros?
