如何将查询结果集转换为字符串

Question

In Java, after executing a query say I got a result set like:

bat 20 10
fat 20 5
cat 10 25

I want this resultset in a string such that the string will be:

bat,20,10 |fat,20,5 |cat,10,25

I am confused. How can I do that in Java?

Answer 1

ResultSet rs = ...
StringBuilder b = new StringBuilder();
while(rs.next()) {
 String s = rs.getString(1);
 int n1 = rs.getInt(2);
 int n2 = rs.getInt(3);
 b.append(s);
 b.append(",");
 b.append(n1);
 b.append(",");
 b.append(n2);
 b.append("|");
}

Answer 2

while iterating through the resultset you can append its contents to a string ..right.?

String finalStr = "";
while(resultSet.next()){
      finalStr+=resultSet.getString(1)+",";
      finalStr+=resultSet.getInt(2).toString()+",";
      finalStr+=resultSet.getInt(3).toString();
      finalStr+="|";
}
