Subject Problems with groupBy
Date Fri, 07 Apr 2006 12:25:15 GMT
Help!!  I am having problems getting my groupBy to work. My query brings back 5 rows, but the
businessEmployeesList collection is not populated for any of the business objects. Here is
my mapping:  

<resultMap id="businessResult" class="business" groupBy="bus_Id">
    <result property=""  />  .................... <-- all properties for this table
</resultMap>

<resultMap id="empRoleResult" class="empRole" groupBy="emp_Id, bus_Id">
    <result property=""  />  ....................  <-- all properties for this table
</resultMap>

<resultMap id="busEmpRoleResult" class="business" extends="businessResult">
    <result property="businessEmployeesList" resultMap="Business.empRoleResult" />
</resultMap>

<select id="getBusEmpRoleByIdNum" parameterClass="java.lang.String" resultMap="busEmpRoleResult">
SELECT *
FROM AIDDB2.BUSINESS AS A
INNER JOIN AIDDB2.ROLE AS B ON A.BUS_ID = B.BUS_ID
WHERE BUS_ID_NUM = #value#
</select>

I am using ArrayList list = (ArrayList)getSqlMapExecutor().queryForList("getBusEmpRoleByIdNum",
idNumber.trim());  to get the data

When I debug this, it appears the businessEmployeesList collection is null, which would seem
to make sense since it appears from the debug statements that the role is being built after
the list is populated (I have debug statements in the constructors).  Where are the Role records
going?  I can see they are being built, but the List I get back only seems to have the 5 business
objects!  I have tried removing the groupBy on the businessResult map, adding it to the busEmpRoleResult
map and every combination of the two, but no approach seems to work.  Does anybody have any
suggestions?  Thanks!!
