When I do the following:

auto rows = mysql.query("select field from my_table limit 50");
foreach(row;rows){
writeln(row["field"]);}
// second time same loop
foreach(row;rows){
writeln(row["field"]);}
I only get the output of the first loop (50 lines), probably
this is a feature
not a bug, but what kind of Object is rows?
A nested loop, did not worked either:
foreach(row;rows){
foreach(field;row){
writeln(field);}
}
Which other ways to access the elements of rows do I have?
Sorry, but I am very new on D, (it may be the best language
available, I don't know yet, but it is really the most
interesting!) thank you!
what if you make array from it:
import std.array: array;
auto rows = mysql.query("select field from my_table limit
50").array;
