Question

好的，这是我当前的查询：

SELECT pk.RxFill.PATIENT_PRICE
,PersonQuotas.QuotaYear
,PersonQuotas.QuotaMonth
(and a bunch of other stuff to link them)
FROM
pk.RxMain
INNER JOIN pk.Doctor
ON pk.RxMain.PHARMACY_ID = pk.Doctor.PHARMACY_ID AND pk.RxMain.DOCTOR_ID = pk.Doctor.DOCTOR_ID
INNER JOIN pk.Formula
ON pk.RxMain.PHARMACY_ID = pk.Formula.PHARMACY_ID AND pk.RxMain.FORMULA_ID = pk.Formula.FORMULA_ID
INNER JOIN pk.Patient
ON pk.RxMain.PHARMACY_ID = pk.Patient.PHARMACY_ID AND pk.RxMain.PATIENT_ID = pk.Patient.PATIENT_ID
INNER JOIN pk.RxFill
ON pk.RxMain.PHARMACY_ID = pk.RxFill.PHARMACY_ID AND pk.RxMain.RXMAIN_ID = pk.RxFill.RXMAIN_ID
INNER JOIN pk.Insurance
ON pk.RxFill.PHARMACY_ID = pk.Insurance.PHARMACY_ID AND pk.RxFill.INSURANCE_ID = pk.Insurance.INSURANCE_ID
INNER JOIN PersonsRepId
ON pk.Doctor.PHARMACY_ID = PersonsRepId.PharmacyId AND pk.Doctor.SALES_PERSON_ID = PersonsRepId.SalesRepId
INNER JOIN Persons
ON PersonsRepId.PersonId = Persons.PersonId
INNER JOIN PersonQuotas
ON Persons.PersonId = PersonQuotas.PersonId
WHERE
Year(pk.RxFill.FILL_DATE) >= Year(GetDate())

我只对最近的QuotaYear / QuotaMonth组合感兴趣，我们的记录数据库会为每个QuotaYear / QuotaMonth组合返回RXFILL行，因为我们已开始在SQL中跟踪它们（所以，我得到2014 / 4,2014 / 5,2014 / 6等等。

为了使问题更加复杂，我的表中可能不存在当前的年/月组合（例如，现在没有人为当前月份输入配额），所以我基本上能够识别最多最近一年/月（两者都以整数形式输入）并仅拉取那些行（以便我可以进行其他计算）。

我该怎么做 - 编辑：这样我就不必知道最近一个月的运行时间是什么？

Answer 1

我正在捅这个，可能会有一些更优化的东西。但基本上，使用CTE过滤年/日，并加入它。

with cte1 as (
    select top 1 max(QuotaYear) as QuotaYear, QuotaMonth
    from PersonQuotas
    group by QuotaMonth
    order by QuotaYear desc, QuotaMonth desc
)
SELECT pk.RxFill.PATIENT_PRICE
,PersonQuotas.QuotaYear
,PersonQuotas.QuotaMonth
--(and a bunch of other stuff to link them)
FROM
pk.RxMain
INNER JOIN pk.Doctor
ON pk.RxMain.PHARMACY_ID = pk.Doctor.PHARMACY_ID AND pk.RxMain.DOCTOR_ID = pk.Doctor.DOCTOR_ID
INNER JOIN pk.Formula
ON pk.RxMain.PHARMACY_ID = pk.Formula.PHARMACY_ID AND pk.RxMain.FORMULA_ID = pk.Formula.FORMULA_ID
INNER JOIN pk.Patient
ON pk.RxMain.PHARMACY_ID = pk.Patient.PHARMACY_ID AND pk.RxMain.PATIENT_ID = pk.Patient.PATIENT_ID
INNER JOIN pk.RxFill
ON pk.RxMain.PHARMACY_ID = pk.RxFill.PHARMACY_ID AND pk.RxMain.RXMAIN_ID = pk.RxFill.RXMAIN_ID
INNER JOIN pk.Insurance
ON pk.RxFill.PHARMACY_ID = pk.Insurance.PHARMACY_ID AND pk.RxFill.INSURANCE_ID = pk.Insurance.INSURANCE_ID
INNER JOIN PersonsRepId
ON pk.Doctor.PHARMACY_ID = PersonsRepId.PharmacyId AND pk.Doctor.SALES_PERSON_ID = PersonsRepId.SalesRepId
INNER JOIN Persons
ON PersonsRepId.PersonId = Persons.PersonId
INNER JOIN PersonQuotas
ON Persons.PersonId = PersonQuotas.PersonId
WHERE
--Year(pk.RxFill.FILL_DATE) >= Year(GetDate())
PersonQuotas.QuotaYear = cte1.QuotaYear
and PersonQuotas.QuotaMonth = cte1.quotaMonth
