Selecionar todo o Banco de Dados MySQL

Leandro O. Alves


Quero vazer uma auto soma de uma coluna que existe em todas as tabelas. abaixo vai o code

$busca = mysql_connect("$local","$usuario","$senha") or die("ERRO AO CONECTAR AO MYSQL, VERIFIQUE COM O ADMINISTRADOR" . mysql_error());        mysql_select_db("$banco") or die("BASE DE DADOS INVÁLIDO");        $pesquisa = mysql_query("SELECT sum(pedn$OPCAO) FROM show tables  data BETWEEN '$data1' AND '$data2'   ");        while($sum = mysql_fetch_array($pesquisa)){        $soma = $sum["sum(pedn$OPCAO)"];        }

Com show tables não funciona, eu nem sei isso pode ser feito, mais desde já agradeço
