Este es el mejor tiempo que he logrado:
Code: Select all  Expand view
DROP TABLE IF EXISTS pruebas ;

CREATE TABLE pruebas  
   SELECT fechemis,td,numdoc,codicont,nombre FROM facturas GROUP BY codicont ;

SELECT * FROM pruebas
WHERE codicont NOT IN (SELECT codicont FROM catalogo WHERE nv = 'S') ;
 

TOTAL TIEMPO: 2.085 Secs
