The simplest would be to have something like the following:

<select id="selectData" resultType="hashmap">
  SELECT SUPPLIERS.SUPPLIER_NAME, ORDERS.ORDER_NUMBER FROM SUPPLIERS, ORDERS WHERE SUPPLIERS.SUPPLIER_ID = ORDERS.SUPPLIER_ID
</select>

Open in new window


because you define an *implicit* resultMap. If you want to define an explicit resultMap you need to have a proper object

package my.pack.age;
public class MyResult {
   String supplier_name;
   int order_number;

    // C'tor and getters/setters
}


<select id="selectData" resultType="my.pack.age.MyResult">
  SELECT SUPPLIERS.SUPPLIER_NAME, ORDERS.ORDER_NUMBER FROM SUPPLIERS, ORDERS WHERE SUPPLIERS.SUPPLIER_ID = ORDERS.SUPPLIER_ID
</select>

Open in new window
