Hi everybody, I have some questions about the results in explain. I don't know exactly what's the diference between "merge join" and "hash join", wich one is faster? What is the meaning of the cost number? Is there any documentation about this? Thanks in advance, -- Diogo de Oliveira Biazus diogo@ikono.com.br Ikono Sistemas e Automação http://www.ikono.com.br
