ResultSet into ResultSet Mysql servlets

Question

Hi!
I have a problem with this code:
while (result.next())
dgenre=statement.executeQuery("select value from table_genre where id_1=1 and id_2=3");                              
if (dgenre.next())
out.println("hello");
dgenre.close();     
println("<br> La dist�ncia �s:" + dist);
i = i+1;
out.println(i);
even if i should be 10, becouse "result" have ten results, the program only do once the bucle.
Is possible that Mysqd doens't allow 1 query into another?
Thanx!

MySQL does not support subselects but that isn't what you're doing, so it shouldn't be an issue. The question is, what are you doing? You're running the exact same query:dgenre=statement.executeQuery("select value from table_genre where id_1=1 and id_2=3"); as many times as this: while (result.next()) {
}is true, which doesn't appear to serve any purpose.
