[jira] Created: (IBATISNET-206) groupBy incorrectly handles left
outer join results where right part is empty
groupBy incorrectly handles left outer join results where right part is empty
-----------------------------------------------------------------------------
Key: IBATISNET-206
URL: https://issues.apache.org/jira/browse/IBATISNET-206
Project: iBatis for .NET
Issue Type: Bug
Components: DataMapper
Affects Versions: DataMapper 1.6
Reporter: Ihar Bury
We use the newly added groupBy functionality as follows:
<resultMap id="ConsumptionHistoryUsers" class="User" groupBy="Id">
<result property="Id" column="id" />
...
<result property="filteredTopContentConsumptionHistory" resultMapping="UserMap.ConsumptionHistoryUsersContent" />
</resultMap>
<resultMap id="ConsumptionHistoryUsersContent" class="Content">
<result property="Id" column="content_id" />
<result property="Creator" resultMapping="UserMap.ConsumptionHistoryUsersContentCreator" />
<result property="DateCreated" column="content_date_created" />
<result property="Title" column="content_title" />
<discriminator type="int" column="content_subtype_id" />
<subMap value="5" resultMapping="ConsumptionHistoryUsersBlog" />
</resultMap>
<resultMap id="ConsumptionHistoryUsersBlog" class="BlogContent" extends="UserMap.ConsumptionHistoryUsersContent">
</resultMap>
The result map is for select SQL like
select *
from User
left outer join Content on ...
This works well in the cases where each selected User has at least one Content joined to it. But when there is one User that doesn't have any corresponding content, a failure occurs. The record returned from the database has values for User and has null values for all Content columns. iBATIS should just store an empty collection to the resulting User object in this case but it tries to load all those nulls as a Content object. In our case that ends up with NullReferenceException while analizing the discriminator value.
subMap = _discriminator.GetSubMap( dataBaseValue.ToString() );
where dataBaseValue == null

Ihar Bury commented on IBATISNET-206:
-------------------------------------
I've uploaded a possible fix we used for our development.
We added an attribute to <result> element called notNullColumn. It should be set to a name of column that cannot be null in a referenced result map.
<resultMap id="ConsumptionHistoryUsers" class="User" groupBy="Id">
<result property="Id" column="id" />
...
<result property="filteredTopContentConsumptionHistory" resultMapping="UserMap.ConsumptionHistoryUsersContent" notNullColumn="content_id" />
</resultMap>
<resultMap id="ConsumptionHistoryUsersContent" class="Content">
<result property="Id" column="content_id" />
<result property="Creator" resultMapping="UserMap.ConsumptionHistoryUsersContentCreator" />
<result property="DateCreated" column="content_date_created" />
<result property="Title" column="content_title" />
<discriminator type="int" column="content_subtype_id" />
<subMap value="5" resultMapping="ConsumptionHistoryUsersBlog" />
