Pass variable outside of closure

Question

var row, userIds = [];

con.query('SELECT * FROM cloud_users', function(err, rows) {
    if(err) throw err;

    for(i=0; i < rows.length; i++) {            
        row = rows[i];
        userIds[row.id] = 'TEST';
    }

    console.log(userIds);
});

console.log(userIds);

First console.log works but not the second. I need to have userIds outside of that closure. How?
