(was: I've found that I didn't use SQLTemplate and #result directive correctly.

If we want to use #result directive, we need to wrap each column in our SQL template to it. For my use-case
{code}
        String sql = "SELECT #result('ID' 'int'), "
                + "#result('DATETIME' 'org.joda.time.DateTime'), "
                + "#result('DATETIME1' 'org.joda.time.DateTime') "
                + "FROM JODA, JODA1";

        EntityResult jodaResult = new EntityResult(Joda.class);
        jodaResult.addDbField(Joda.ID_PK_COLUMN, "ID");
        jodaResult.addObjectField(Joda.DATETIME_PROPERTY, "DATETIME");

        SQLResult resultDescriptor = new SQLResult();
        resultDescriptor.addEntityResult(jodaResult);
        resultDescriptor.addColumnResult("DATETIME1");

        SQLTemplate query = new SQLTemplate(Joda.class, sql);
        query.setResult(resultDescriptor);
{code}

With aliases
{code}
        String sql = "SELECT #result('j.ID' 'int' 'ID'), "
                + "#result('j.DATETIME' 'org.joda.time.DateTime' 'DATETIME'), "
                + "#result('DATETIME1' 'org.joda.time.DateTime') "
                + "FROM JODA j, JODA1";

        EntityResult jodaResult = new EntityResult(Joda.class);
        jodaResult.addDbField(Joda.ID_PK_COLUMN, "ID");
        jodaResult.addObjectField(Joda.DATETIME_PROPERTY, "DATETIME");

        SQLResult resultDescriptor = new SQLResult();
        resultDescriptor.addEntityResult(jodaResult);
        resultDescriptor.addColumnResult("DATETIME1");

        SQLTemplate query = new SQLTemplate(Joda.class, sql);
        query.setResult(resultDescriptor);
{code}

In both of the examples above, I've had the same correct result
{noformat}
class org.example.cayenne.persistent.Joda
class org.joda.time.DateTime
{noformat})

> SQLTemplateAction doesn't consider javaType from #result directive when configurating RowDescriptorBuilder. It put to RowDescriptorBuilder.typeOverrides only types from current ObjEntity and DbEntity. 
> So the following example doesn't work correctly.
> I added Joda DateTimeType provided by John Huss in [CAY-1626|https://issues.apache.org/jira/browse/CAY-1626] to the ExtendedType.
> Than I created two DbEntities with fields of TIMESTAMP type and one dependent ObjEntity.
> {code:xml|tittle=datamap}
> 	<db-entity name="JODA">
> 		<db-attribute name="DATETIME" type="TIMESTAMP"/>
> 		<db-attribute name="ID" type="INTEGER" isPrimaryKey="true" isMandatory="true"/>
> 	</db-entity>
> 	<db-entity name="JODA1">
> 		<db-attribute name="DATETIME1" type="TIMESTAMP"/>
> 	</db-entity>
> 	<obj-entity name="Joda" className="org.example.cayenne.persistent.Joda" dbEntityName="JODA">
> 		<obj-attribute name="datetime" type="org.joda.time.DateTime" db-attribute-path="DATETIME"/>
> 	</obj-entity>
> {code}
> And I got java.util.Date instead of org.joda.time.DateTime for column DATETIME1 AS D by the code below.
> {code}
>         String sql = "SELECT j.ID, "
>                 + "#result('j.DATETIME' 'org.joda.time.DateTime' '' 'JODA.DATETIME'), "
>                 + "#result('DATETIME1' 'org.joda.time.DateTime' '' 'JODA1.DATETIME1') AS D "
>                 + "FROM JODA j, JODA1";
>         EntityResult jodaResult = new EntityResult(Joda.class);
