访问交叉表数据透视报表-需要使用总计字段的计算字段

Question

我有一个可以访问的交叉表报表，但是我需要计算总值的百分比。 SQL是：

TRANSFORM Count(qryPhysicianAdmitsFull.PhysicianID) AS CountOfPhysicianID
SELECT qryPhysicianAdmitsFull.Facility AS Facility, qryPhysicianAdmitsFull.[Primary Physician] AS Physician, Count(qryPhysicianAdmitsFull.PhysicianID) AS [Total Of PhysicianID]
FROM qryPhysicianAdmitsFull
GROUP BY qryPhysicianAdmitsFull.Facility, qryPhysicianAdmitsFull.[Primary Physician]
ORDER BY qryPhysicianAdmitsFull.Facility, qryPhysicianAdmitsFull.[Primary Physician]
PIVOT qryPhysicianAdmitsFull.Readmit;

我想计算每组PhysicianID的（（Readmit总数）/（医师ID数）* 100），并显示包含PhysicianID和Readmit计数的列。

我认为作为子查询是合适的，但到目前为止还没有乐趣。

谢谢
