Obter resultado do Join de duas tabelas


Recommended Posts

Boa tarde!

Estou a fazer um inner join de duas tabelas...


CREATE DEFINER=`root`@`localhost` PROCEDURE `Join`()

 Select sip2.temp_teste.sitio
 from sip2.temp_teste
   inner join sip2.teste
   on sip2.temp_teste.sitio = sip2.teste.sitio;

E gostava de saber como consigo saber o resultado do Join?

Pois, se o Join for 0, quer dizer que não há valores iguais, entao eu faria o insert dos registos da tabela temporária para a tabela final...

Alguém me pode explicar como posso fazer?
