Oh sorry! I used wrong host! All ok!

Yes, there was issue with host name, but it's do not solve problem. Second DB have same fields and I still getting false instead moving into while loop

It's look like it do `next` step before return something.
So if in DB 1 value it will work like:
do step
if no value after it --> return false
if yes --> return true

but I need any way to check if first value in DB is exists. Any suggestion?

If you expect to have single or zero rows in result, use
if (rs.next()) {
            dbuser = rs.getString(1);
            dbpassword = rs.getString(2);
            writeln(dbuser);
} else {
            writeln("user not found");
}
