sql - 複数行の集計 SQL Server 2008

Question

これは、このクエリhereの拡張です。現在正しい結果セットがあり、次のようになっています。

MD Name | # PTS | Med Staff | AVG LOS | AVG Bench LOS | AVG DIFF
MCP     |    4  | Ortho SX  | 8.000000| 2.650000      | 5.350000

この結果に追加したいのは、部門で見られた患者の合計と、同じ平均ですが、部門全体の平均です。上記の元のクエリに別の列を追加して、次のようにすることで、部門ごとの合計患者数を正しく集計することができました。

(SELECT
    COUNT(DISTINCT V.PT_ID) 
    FROM smsdss.pract_dim_v p
    JOIN smsmir.vst_rpt v
    on v.adm_pract_no = p.src_pract_no
    WHERE pv.med_staff_dept = p.med_staff_dept
    AND v.adm_dtime BETWEEN @STARTDATE AND @ENDATE
    AND v.vst_type_cd = 'I'
    AND p.spclty_desc != 'NO DESCRIPTION'
    --AND pv.spclty_desc NOT LIKE 'HOSPITALIST%'
    AND v.drg_std_days_stay IS NOT NULL
    AND p.pract_rpt_name != '?'
    AND p.orgz_cd = 's0x0'
    AND p.med_staff_dept IN (
    'INTERNAL MEDICINE',
    'FAMILY PRACTICE',
    'SURGERY'
    )
) AS '# PTS For Dept'

合計を手動で確認しましたが、正しいです。p.med_staff_dept に AVG LOS、AVG BENCH LOS、および AVG DIFF を追加したいことはわかっています。ここから、ワック・ア・ドゥー (技術用語) の結果が得られ始めます。

これは、部門ごとの AVG LOS を取得しようとする部分です。

(SELECT
    AVG(v.len_of_stay)
    FROM smsdss.pract_dim_v p
    JOIN smsmir.vst_rpt v
    ON v.adm_pract_no = p.src_pract_no
    WHERE pv.med_staff_dept = p.med_staff_dept
    AND v.adm_dtime BETWEEN @STARTDATE AND @ENDATE
    AND v.vst_type_cd = 'I'
    AND p.spclty_desc != 'NO DESCRIPTION'
    --AND pv.spclty_desc NOT LIKE 'HOSPITALIST%'
    AND v.drg_std_days_stay IS NOT NULL
    AND p.pract_rpt_name != '?'
    AND p.orgz_cd = 's0x0'
    AND p.med_staff_dept IN (
    'INTERNAL MEDICINE',
    'FAMILY PRACTICE',
    'SURGERY'
    )
) AS 'DEPT ALOS'

私のグループのうちの 2 つは、Excel と照合すると正しい数値を取得しますが、行の中央のグループは次のように非常に正しくありません。

# PTS FOR DEPT | DEPT ALOS
330            | 5.284848 <-- SAME IN EXCEL
737            | 4.952510 <-- EXCEL SHOWS 196 AND 6.214285
111            | 3.072072 <-- SAME IN EXCEL

これは、合計でクエリの FROM 句です。

FROM smsmir.vst_rpt vr
JOIN smsdss.pract_dim_v pv
ON vr.adm_pract_no = pv.src_pract_no

WHERE vr.adm_dtime BETWEEN @STARTDATE AND @ENDATE
AND vr.vst_type_cd = 'I'
AND pv.spclty_desc != 'NO DESCRIPTION'
--AND pv.spclty_desc NOT LIKE 'HOSPITALIST%'
AND vr.drg_std_days_stay IS NOT NULL
AND pv.pract_rpt_name != '?'
AND pv.orgz_cd = 's0x0'
AND pv.med_staff_dept IN (
'INTERNAL MEDICINE',
'FAMILY PRACTICE',
'SURGERY'
)
GROUP BY pv.pract_rpt_name, pv.med_staff_dept, pv.spclty_desc
ORDER BY pv.med_staff_dept, AVG(vr.len_of_stay - vr.drg_std_days_stay)DESC

望ましい最終出力:

MD NAME | # PTS | MED STAFF | AVG LOS | AVG BENCH | AVG DIFF | DEPT TOT | AVG LOS | AVG BNCH | AVG DIFF
MCP     |   4   | Ortho SX  | 8.000000| 2.650000  | 5.350000 | 300      | 4.990000| 4.500000 | 0.490000

内科の番号はどれも正しく出ていません。

私が見つけた問題はここにあります：

, (SELECT
    COUNT(DISTINCT V.PT_ID) 
    FROM smsdss.pract_dim_v p
    JOIN smsmir.vst_rpt v
    on v.adm_pract_no = p.src_pract_no
    WHERE pv.med_staff_dept = p.med_staff_dept
    AND v.adm_dtime BETWEEN @STARTDATE AND @ENDATE
    AND v.vst_type_cd = 'I'
    AND p.spclty_desc != 'NO DESCRIPTION'
    AND pv.spclty_desc NOT LIKE 'HOSPITALIST%' <-- should be p.spclty not pv.
    AND v.drg_std_days_stay IS NOT NULL
    AND p.pract_rpt_name != '?'
    AND p.orgz_cd = 's0x0'
    AND p.med_staff_dept IN (
    'INTERNAL MEDICINE',
    'FAMILY PRACTICE',
    'SURGERY'
    )
) AS '# PTS For Dept'

両方の列選択ステートメントで pv.spclty_desc を p.spclty_desc に変更することで、問題が修正されました。しかし、これは、ステートメントで内部医療のみが失敗し、他の2つは失敗しなかった理由を教えてくれません.
