的SQL Server 2008：計數鍵數目在多個日期範圍跨多個表

Question

感謝今天早上誰回答我的問題的人：

SQL Server 2008: Count Number of Keys In Multiple Date Ranges

這是它的一個擴展，我不清楚如何將此前的解決方案概括爲這種情況。

我正在使用的數據庫具有藥物，實驗室值和幾個表格中的一組患者的診斷。與上述類似的問題：

多年來，X = 1996 - 2008年：

我要計數的患者認爲有X年規定的特定藥物的數量，採取了X年特定實驗室值，（這最後一個是有點不同！） 和1996年或以後首次給出的具體診斷，這在第x年還沒有得到解決。

編輯：原來，pt_id是不任何表的主鍵 - 從我一直在讀SELECT COUNT DISTINCT(pm.pt_id)（因爲DISTINCT正在緩慢），但我會被罰款與使用不同的解決方案如果它工作。

這裏是2008年單獨查詢，但我又希望有一個查詢，將計算，每年從1996年的值至2008年

SELECT COUNT (pm.pt_id) 
FROM dm.medications pm 
/*patient was prescribed statins together with fibrates this year*/ 
WHERE pm.pt_id IN 
(
    SELECT statins.pt_id 
    FROM dm.patient_medications statins 
    INNER JOIN dm.patient_medications other_meds 
    ON statins.pt_id = other_meds.pt_id 
    WHERE Year(other_meds.order_dts) = 2008 
    AND Year(statins.order_dts) = 2008 
    AND statins.generic_nm in ('Atorvastatin','Cerivastatin') 
    AND other_meds.generic_nm in ('Clofibrate','Fenofibrate','Gemfibrozil') 
) 
/* patient had a diagnosis code in the list first diagnosed in 1996 or later and not yet resolved in this year */ 
WHERE pm.pt_id in 
(
    SELECT pd.pt_id, 
    FROM dm.diagnoses pd 
    WHERE pd.icd9_cd IN('728.89','729.1','710.4','728.3','729.0','728.81','781.0','791.3') 
    AND Year(pd.init_noted_dts) >= 1996 
    AND pd.rslvd_dts IS NOT NULL 
    AND Year(pd.rslvd_dts) >= 2008 
) 
/* patient had a lab value above 1000 this year */ 
AND pm.pt_id IN 
(
    SELECT pl.pt_id 
    FROM dm.labs pl 
    WHERE pl.lab_val > 1000 
    AND pl.lab_val IS NOT NULL 
    AND pl.lab_val < 999999 
    AND pl.lab_nm = 'CK (CPK)' 
    AND Year(pm.order_dts) = 2008 
) 
/* we have demographic information about this patient */ 
AND pm.pt_id IN 
(
    SELECT p.pt_id 
    FROM mrd.demographics p 
) 
/* this is a real person */ 
AND pm.pt_id IS NOT NULL 

Answer 1

試試這個：再次

SELECT COUNT(*), t1.year 
FROM dm.medications pm 
/*patient was prescribed statins together with fibrates this year*/ 
inner join (
    SELECT statins.pt_id, Year(other_meds.order_dts) as Year 
    FROM dm.patient_medications statins 
    INNER JOIN dm.patient_medications other_meds ON statins.pt_id = other_meds.pt_id 
     AND Year(other_meds.order_dts) = Year(statins.order_dts) 
    WHERE statins.generic_nm in ('Atorvastatin','Cerivastatin') 
     AND other_meds.generic_nm in ('Clofibrate','Fenofibrate','Gemfibrozil') 
) t1 on pm.pt_id = t1.pt_id 
/* patient had a diagnosis code in the list first diagnosed in 1996 or later and not yet resolved in this year */ 
left outer join 
(
    SELECT pd.pt_id, Year(pd.rslvd_dts) as Year 
    FROM dm.diagnoses pd 
    WHERE pd.icd9_cd IN ('728.89','729.1','710.4','728.3','729.0','728.81','781.0','791.3') 
     AND Year(pd.init_noted_dts) >= 1996 
) t2 on pm.pt_id = t2.pt_id and t1.Year = t2.Year 
/* patient had a lab value above 1000 this year */ 
inner join (
SELECT pl.pt_id, Year(pm.order_dts) as Year 
    FROM dm.labs pl 
    WHERE pl.lab_val > 1000 
     AND pl.lab_val < 999999 
     AND pl.lab_nm = 'CK (CPK)' 
) t3 on pm.pt_id = t3.pt_id and t2.Year = t3.Year 
/* we have demographic information about this patient */ 
inner join (
    SELECT p.pt_id 
    FROM mrd.demographics p  
) t4 on pm.pt_id = t4.pt_id and t3.Year = t4.Year 
/* this is a real person */ 
where pm.pt_id IS NOT NULL 
    and t1.year between 1996 and 2008 
    and t2.Year is null 
group by t1.year
