Pessoal A Embarcadero disponibilizou um "white paper" escrito pelo Jonathan Lewis: Writing Optimal SQL.
Pelo que li, por cima, é baseado numa apresentação dele (mas sem as ilustrações dos slides...). Vou enviar o arquivo ao Chiappa, para armazenar na área de arquivos do grupo. Quem quiser, também pode se inscrever para receber o link de download... mas a mensagem diz que o documento pode ser compartilhado.
