緣由：把數據從Oracle遷移到MySQL後，致使D_Region表的字段PARENTID一些在Oracle中值爲NULL行在導入到MySQL後
變成了空值（即''),而在MDX Schema中又採用以下配置
        <Dimension name="Region D" caption="區域" foreignKey="REGION_ID">
           <Hierarchy hasAll="true" allMemberName="All Regions D" allMemberCaption="雲南省"  primaryKey="ID">
              <Table name="D_REGION"/>
          <Level name="Region Id" uniqueMembers="true" type="Numeric" column="ID" 
                         nameColumn="NAME" parentColumn="PARENTID" nullParentValue="null">
         <Closure parentColumn="PARENT_ID" childColumn="ID">
            <Table name="C_REGION_CLOSURE"/>
         </Closure>
            <Property name="Name" column="NAME"/>
            <Property name="Div Level" column="DIVLEVEL"/>
               </Level>
           </Hierarchy>
         </Dimension>
紅字部分致使MDX語句在MySQL中獲取'[Region D].[雲南省].[昆明市]'的Member找不到父節點標識。
解決：把MySQL中表D_REGION中全部PARENTID爲空的字段改成一個特殊標識值，如-1。
而後，更改MDX Schema爲以下配置
......
                nullParentValue="-1" ......
