Question

我想在表中添加其他（缺少的）行。现有情况：我有一个患者表，其中是注册日期，我计算患者已经在几周内注册了多长时间（＆＃34; TimeInProgram＆＃34;）。现在我对此进行汇总以获得当前在此期间的患者数量（参见COUNT - ＆gt;属性＆＃34;患者＆＃34;）。最后，我总结了一个窗口函数，以获得在特定时期内已经存在的患者数量。

SELECT aggregation.*, SUM("Patients") OVER () "All", SUM("Patients") OVER (ORDER BY "TimeInProgram" DESC ROWS UNBOUNDED PRECEDING) "PatientsCounterInTime" FROM (
SELECT COUNT(DISTINCT "PatientID") "Patients", "TimeInProgram" FROM (
SELECT
    pat."PatientID",
    ROUND(((DAYS_BETWEEN(pat."RegisteredOnDate", NOW())+1)/7.0), 0, 'ROUND_UP') "TimeInProgram"
    FROM t_patient pat
    ORDER BY "PatientID"
) data
GROUP BY "TimeInProgram"
ORDER BY "TimeInProgram"
) aggregation

您可以在此处看到结果：

PatientsCounterInTime PLUS以下行的患者是下一行的PatientsCounterInTime的值。您可以看到问题：有一些＆＃34; TimeInProgram＆＃34; -weeks缺失，如第4周或第5周，因为在那个时期没有病人。所以我想添加缺少的行。＆＃34; PatientsCounterInTime＆＃34;的价值在第4周，第5周应该是162，并且＆＃34;患者＆＃34;当然是0。

我使用HANA作为数据库。

亲切的问候和提前谢谢。

更新：

  SELECT "TiP" "TimeInProgram", "Patients", "PatientsCounterInTime" FROM (
        SELECT aggregation.*, SUM("Patients") OVER () "All", SUM("Patients") OVER (ORDER BY "TimeInProgram" DESC ROWS UNBOUNDED PRECEDING) "PatientsCounterInTime" FROM (
        SELECT COUNT(DISTINCT "PatientID") "Patients", "TimeInProgram" FROM (
        SELECT
            pat."PatientID",
            ROUND(((DAYS_BETWEEN(pat."RegisteredOnDate", NOW())+1)/7.0), 0, 'ROUND_UP') "TimeInProgram"
            FROM "t_patient" pat
            ORDER BY "PatientID"
        ) data 
        GROUP BY "TimeInProgram"
        ORDER BY "TimeInProgram"
        ) aggregation
    )
    RIGHT JOIN "t_time_in_program" t ON "TimeInProgram" = t."TiP";

（PatientsCounterInTime PLUS以下行的患者是下一行的PatientsCounterInTime的值。）

您可以在“_SYS_BI”架构中找到时间表。如果没有，here是有用的文章

以下是如何使用它的示例。假设您要显示从2000年到当前年份的时间段：

WITH dataset AS (
    Select '2016' as YEAR, '216' AS PATIENTS FROM DUMMY
    union all
    Select '2010' as YEAR, '200' AS PATIENTS FROM DUMMY 
)
SELECT 
        distinct tdim.year,
        case when dataset.PATIENTS is null then 0 else dataset.PATIENTS end  
    FROM "_SYS_BI"."M_TIME_DIMENSION_MONTH" tdim
left outer join  dataset on tdim.year = dataset.year
where tdim.year >=2000 and tdim.year <= YEAR(CURRENT_DATE)

如果您可以发送表创建语句+数据的一些插入，那就太棒了，所以我可能会帮助您更多。
