(原创，到现在为至最为复杂的SQL查询代码)实现按部门月卡余额总额分组统计的SQL查询代码(在Ms SQL Server中调试通过)

SELECT dp.dpname1 AS 部门, cust_dp_SumOddfre.sum_oddfare AS 当月卡总余额

FROM (SELECT T_Department.DpCode1, SUM(custid_SumOddfare_group.sum_oddfare)

AS sum_oddfare

FROM (SELECT l2.CustomerID, SUM(r1.oddfare) AS sum_oddfare

FROM (SELECT CustomerID, MAX(OpCount) AS max_opcount

FROM (SELECT CustomerID, OpCount, RTRIM(CAST(YEAR(OpDt)

AS char)) + '-' + RTRIM(CAST(MONTH(OpDt) AS char))

+ '-' + RTRIM(DAY(0)) AS dt

FROM T_ConsumeRec

UNION

SELECT CustomerID, OpCount, RTRIM(CAST(YEAR(cashDt)

AS char)) + '-' + RTRIM(CAST(MONTH(cashDt) AS char))

+ '-' + RTRIM(DAY(0)) AS dt

FROM T_Cashrec) l1

WHERE (dt <= '2005-6-1')/*输入查询月份,可用参数传递*/

GROUP BY CustomerID) l2 INNER JOIN

(SELECT CustomerID, OpCount, oddfare

FROM T_ConsumeRec

UNION

SELECT CustomerID, OpCount, oddfare

FROM T_Cashrec) r1 ON l2.CustomerID = r1.CustomerID AND

r1.OpCount = l2.max_opcount

GROUP BY l2.CustomerID) custid_SumOddfare_group INNER JOIN

T_Customers ON

custid_SumOddfare_group.CustomerID = T_Customers.CustomerID INNER JOIN

T_Department ON SUBSTRING(T_Customers.Account, 1, 2)

= T_Department.DpCode1 AND SUBSTRING(T_Customers.Account, 3, 2)

= T_Department.DpCode2 AND SUBSTRING(T_Customers.Account, 5, 3)

= T_Department.DpCode3

GROUP BY DpCode1) cust_dp_SumOddfre INNER JOIN

(SELECT DISTINCT dpcode1, dpname1

FROM t_department) dp ON dp.dpcode1 = cust_dp_SumOddfre.DpCode1

附：查询用到的基本表形成脚本：
