How to read a variable outside of the brackets? (or a loop)

Question

Example: How to get the value of the var idMedico outside of the connection brackets?

connection.query("SELECT idmedicos FROM medicos WHERE nome = '" + medico + "'", function (err, result) {
        var idMedico = result[0].idmedicos;
    });

        var idMedico = result[0].idmedicos;
        callback(idMedico);
    });

}


query('medico', function(result){
    console.log('result : ' + result)
});

Thank you for you help :) But it didn't work ;( – Luiz Gustavo Apr 29 '20 at 13:00
Define "It didn't work". This solution is the way to go. Just pass `result` to another function. – Jeremy Thille Apr 29 '20 at 13:08
