一、度量抒寫

1、Measure要寫在CalculatedMember之前，否則此度量在介面中無法顯示。

<!-- 掛號人次 -->
	<Measure name="掛號人次" aggregator="sum" formatString="###,###,###">
		<MeasureExpression>
			<SQL dialect="generic">
				(case when Fact_Prescription_Detail_view.GH_status = 5 then 1 else 0 end)
			</SQL>
		</MeasureExpression>
	</Measure>
    <!--藥品種數-->
    <Measure name="藥品種數" aggregator="distinct-count" column="Pres_Item_Name" formatString="###,###,###"></Measure>
    <!--就診人次-->
    <Measure name="就診人次" aggregator="distinct-count" column="Visitno" formatString="###,###,###"></Measure>

    <!--抗菌藥人次比例-->
	<CalculatedMember name="人均藥品種數" dimension="Measures" formatString="###,###,###">
      <Formula>IIF(([Measures].[就診人次]=0),null,round(([Measures].[藥品種數])/([Measures].[就診人次])))</Formula>
    </CalculatedMember>
