Hello Larry,

in the above example; can I get only the second column back with  resultClass="String"
without resultmap? I mean how can I map it?

I have a group by query with more than one column, but only one of them is to be mapped
(the first one in this case). How can I do it whithout defining a class for it?

  <select id="Chk_Vordruck" resultClass="String">
        SELECT formular_vordruck_name AS Vordruck_Name,
               Formular_UFA AS Unterfallart,
               MIN(formular_jahr) AS min_jahr,
               MAX(formular_jahr) AS max_jahr
        FROM Formular
        GROUP BY formular_vordruck_name,
                 Formular_UFA
  </select>



thank you
regards
kambiz

You can't currently get a list of lists, but you can get a list of maps:

<select id="getClusterNames" resultClass="hashmap">
