Javascript 如何在数据源文件（.xml）中定义3个表的视图

我想在一个数据源中定义一个包含3个表的视图 文件，但我不知道确切的语法！你能帮我吗？ PS：我不知道我是否使用了正确的语法。事实上，我甚至不知道我们应该把这3张桌子放在同一个标签上还是单独的标签上！ 谢谢你的帮助， 这是我的密码：

<DataSource 
    dbName="SQLServer_CRM"
    tableName="crm_objects"
    ID="crm_objects"
    dataSourceVersion="1"
    generatedBy="v8.3p"

    <!--

    <fields>

        <field name="crm_obj_parent_idnum"          title="Parent ID"           type="integer"      foreignKey="crm_objects.crm_obj_idnum" rootValue="1" detail="true" required="true" canSave="true" canEdit="false"  hidden="true"/>

    </fields>

    <operationBindings>

        <operationBinding operationType="fetch">

            <whereClause>crm_objects.crm_obj_kind = crm_kind.crm_kind_idnum AND crm_objects.crm_obj_idnum = crm_attrdata.crm_attrdat_fk_obj_idnum AND ($defaultWhereClause)</whereClause>
        </operationBinding>
    </operationBindings>

    <!-- <operationBindings>

        </operationBinding>

    </operationBindings> -->
</DataSource>

以下是解决方案：
