Bala commented on IBATIS-406:
-----------------------------
Im also facing the same problem, with slightly diffrent requirement
my sqlMap entry .
<select id="querySearch" parameterClass="java.util.HashMap"
resultClass="java.util.HashMap">
$query$
</select>
query ="select c.id from table_C c ,table_M m where m.id=c.id"
second time im shifting the query like
query ="select m.name from table_C c ,table_M m where m.id=c.id"
im getting an error
Exception:: THREAD: http-8084-Processor20; MSG: [Error getting items:
--- The error occurred in sqlSearch.xml.
--- The error occurred while applying a result map.
--- Check the sqlSearch.querySearch-AutoResultMap.
--- Check the result mapping for the 'ID' property.
--- Cause: java.sql.SQLException: Invalid column name] Error getting items:
--- The error occurred in sqlSearch.xml.
--- The error occurred while applying a result map.
--- Check the sqlSearch.querySearch-AutoResultMap.
--- Check the result mapping for the ID property.
looks like ,still the old resultClass HasMap object used for new resultset.

> In Ibatis using sqlMaps, we are able to do embedded resultMaps within
> resultMaps. If we have one resultMap with only one result that is a
> resultMap (ie <result property="userAbsence"
> resultMap="User.UserAbsenceResult"/> )then using the groupby attribute has
> the effect of grouping by that property.
> However, if we have one resultMap that has multiple results that are
> resultMap then the group by only works for the first embedded item.
> Below is a working code snippet that uses embedded resultMaps. Adding the
> groupby attribute forces the class that is returned to only return one item
> per groupby key.

> Planning to get around this by creating separate SQLs for the userAbesence
> and the userSkill. Since we are only expecting 1 userID at a time we don't
> expect much overhead, then from the individual sqls for userSkill and
> userAbsence I can do the group by within the query. Does anyone have any
> other suggestions?
