queryForList vs queryForObject

[Engel, Gregory A]

With the follwing result map using a list property "contact" works perfectly and always returns a single value as expected.

However if I use an object property "primaryContact" I get the following error.

 

--- The error occurred in com/tms/ede/server/persistance/dao/sqlmapdao/sourcesmaps/maps/EDEProgservMap.xml. 
--- The error occurred while applying a result map. 
--- Check the EDEProgservRSMap_Primary. 
--- Check the result mapping for the 'primaryContact' property. 
--- Cause: java.sql.SQLException: Error: executeQueryForObject returned too many results.
Caused by: java.sql.SQLException: Error: executeQueryForObject returned too many results.

I can't understand what's going on here. I always get a single value in the returned list which is what I want but if I use the

same query with a query for object I get an error.

 

Heres the resultmap

 

<resultMap id="EDEProgservRSMap_Primary" class="com.tms.ede.server.persistance.dao.sqlmapdao.sourcesmaps.vo.EDEProgservVO">
 <result property="id" column="progserv_id"/>
 <result property="statusId" column="progserv_status_id"/>
 <result property="sourceId" column="source_id"/>
 <result property="curTmsCallSign" column="call_sign_text"/>
 <result property="sourceName" column="source_name"/>
 <result property="finderText" column="source_finder_text"/>
 <!--result property="contacts" column="source_id" select="getPrimaryContactVOBy_SourceId_PrimaryOnly"/-->
 <result property="primaryContact" column="source_id" select="getPrimaryContactVOBy_SourceId_PrimaryOnly"/>
</resultMap>

 

Here's the sql map...

 

<statement id="getPrimaryContactVOBy_SourceId_PrimaryOnly"
 parameterClass="java.lang.Long"
 resultClass="com.tms.ede.server.persistance.dao.sqlmapdao.sourcesmaps.vo.PrimaryContactVO"
 resultMap="PrimaryContactRSMap"
>

 

SELECT
 source.source_id,
 source_contact.contact_group_owner_id,
 source_contact_group.contact_id,
 contact.contact_type_id,
 contact.first_name,
 contact.last_name,
 contact.job_title,
 contact.email_address,
 contact.department
FROM
 source,
 source_contact,
 source_contact_group,
 contact
WHERE
 source.source_id = #value#
AND
 source.source_id=source_contact.source_id
AND
 source_contact.contact_group_owner_id=source_contact_group.contact_group_owner_id
AND
 source_contact_group.contact_id=contact.contact_id
AND
 contact.contact_type_id = 57
</statement>
