Question

我正在尝试将某些行转换为SQL Server中的列，但所有连接的表都让我感到困惑。我不知道在哪里或如何添加CASE或PIVOT。

DECLARE @BeginDateTime DATETIME
DECLARE @EndDateTime DATETIME
SET @BeginDateTime = '20170901'
SET @EndDateTime = '20170922'

SELECT DISTINCT     
CONVERT(VARCHAR(10), BILL_TABLE.srvc_thru_dt, 101) AS DischargeDate, PATIENT_TABLE.[Master Patient ID] AS MedRec, PATIENT_TABLE.[Hospital #] AS VisitID, LOCATION_TABLE.loc_ds AS Location, PERSON_TABLE.lst_nm AS LastName, PERSON_TABLE.fst_nm AS FirstName, CONVERT(VARCHAR(10), PATIENT_TABLE.[Date of Birth], 101) AS DOB, PATIENT_TABLE.ZIP, DIAGNOSIS_TABLE.ICD9_diag_ty + CONVERT(VARCHAR(10),DIAGNOSIS_TABLE.ICD9_rank_no) AS DxRank, CODING_TABLE.icd9_code AS Dx

FROM         BILL_TABLE INNER JOIN
             PATIENT_TABLE ON BILL_TABLE.vst_int_id = PATIENT_TABLE.[Visit #] INNER JOIN
             PERSON_TABLE ON PATIENT_TABLE.psn_int_id = PERSON_TABLE.psn_int_id LEFT OUTER JOIN
             LOCATION_TABLE ON PATIENT_TABLE.loc_lvl_5_id = LOCATION_TABLE.loc_int_id LEFT OUTER JOIN
             DIAGNOSIS_TABLE ON PATIENT_TABLE.[Visit #] = DIAGNOSIS_TABLE.vst_int_id LEFT OUTER JOIN
             CODING_TABLE ON DIAGNOSIS_TABLE.icd9_int_id = CODING_TABLE.icd9_int_id

WHERE  (bil_cre_dt >= @BeginDateTime) AND 
    bil_cre_dt < @EndDateTime AND
    srvc_cd_int_id IN (20329, 21912, 20332, 20333, 20335, 20337, 20339, 20340, 20341, 20343) AND
    DIAGNOSIS_TABLE.ICD9_diag_ty != 'A'

这给了我以下结果：

 DischargeDate  | MedRec | VisitID | Location | LastName | FirstName |    DOB    |  ZIP  | DxRank |  Dx
 ---------------|--------|---------|----------|----------|-----------|-----------|-------|--------|------   
 09/20/2017     |  12345 |  111100 |    203   |  TESTER  |    JEFF   | 01/01/1984| 90210 |   P1   | 4005A
 09/20/2017     |  12345 |  111100 |    203   |  TESTER  |    JEFF   | 01/01/1984| 90210 |   S2   | R42
 09/20/2017     |  12345 |  111100 |    203   |  TESTER  |    JEFF   | 01/01/1984| 90210 |   S3   | E860
 09/21/2017     |  23456 |  111101 |    205   |  TESTER  |    BILL   | 02/02/2007| 45321 |   P1   | N390

我需要将结果看起来像这样：

DischargeDate  | MedRec | VisitID | Location | LastName | FirstName |    DOB    |  ZIP  |  P1  |  S2  |  S3
---------------|--------|---------|----------|----------|-----------|-----------|-------|------|------|-------   
09/20/2017     |  12345 |  111100 |    203   |  TESTER  |    JEFF   | 01/01/1984| 90210 |4005A |  R42 | E860
09/21/2017     |  23456 |  111101 |    205   |  TESTER  |    BILL   | 02/02/2007| 45321 |N39   |  NULL| NULL

Answer 1

我无法运行此查询，但我认为这应该有效 -

DECLARE @BeginDateTime DATETIME
DECLARE @EndDateTime DATETIME
SET @BeginDateTime = '20170901'
SET @EndDateTime = '20170922'

;WITH PIVOTDATA
AS
(
    SELECT DISTINCT     
        CONVERT(VARCHAR(10), BT.srvc_thru_dt, 101) AS DischargeDate, 
        PT.[Master Patient ID] AS MedRec, 
        PT.[Hospital #] AS VisitID, 
        LT.loc_ds AS Location, 
        PT1.lst_nm AS LastName, 
        PT1.fst_nm AS FirstName, 
        CONVERT(VARCHAR(10), PT.[Date of Birth], 101) AS DOB, 
        PT.ZIP, 
        DT.ICD9_diag_ty + CONVERT(VARCHAR(10),DT.ICD9_rank_no) AS DxRank, 
        CT.icd9_code AS Dx
    FROM BILL_TABLE  BT
    INNER JOIN PATIENT_TABLE PT
    ON BT.vst_int_id = PT.[Visit #] 
    INNER JOIN PERSON_TABLE PT1
    ON PT.psn_int_id = PT1.psn_int_id 
    LEFT OUTER JOIN LOCATION_TABLE LT 
    ON PT.loc_lvl_5_id = LT.loc_int_id 
    LEFT OUTER JOIN DIAGNOSIS_TABLE DT 
    ON PT.[Visit #] = DT.vst_int_id 
    LEFT OUTER JOIN CODING_TABLE CT
    ON DT.icd9_int_id = CT.icd9_int_id
    WHERE  (bil_cre_dt >= @BeginDateTime)  
       AND bil_cre_dt < @EndDateTime
       AND srvc_cd_int_id IN (20329, 21912, 20332, 20333, 20335, 20337, 20339, 20340, 20341, 20343)
       AND DT.ICD9_diag_ty != 'A'
)
SELECT 
    DischargeDate,
    MedRec,
    VisitID,
    Location,
    LastName,
    FirstName,
    DOB,
    ZIP,
    P1, S2, S3
FROM PIVOTDATA
PIVOT(MAX(Dx) FOR DxRank IN (P1, S2, S3)) AS P;

试试这个：

DECLARE @BeginDateTime DATETIME
DECLARE @EndDateTime DATETIME
SET @BeginDateTime = '20170901'
SET @EndDateTime = '20170922'

SELECT DISTINCT     
CONVERT(VARCHAR(10), BILL_TABLE.srvc_thru_dt, 101) AS DischargeDate, PATIENT_TABLE.[Master Patient ID] AS MedRec, PATIENT_TABLE.[Hospital #] AS VisitID, LOCATION_TABLE.loc_ds AS Location,
 PERSON_TABLE.lst_nm AS LastName, PERSON_TABLE.fst_nm AS FirstName, CONVERT(VARCHAR(10), PATIENT_TABLE.[Date of Birth], 101) AS DOB,
  PATIENT_TABLE.ZIP, 
CASE when (DIAGNOSIS_TABLE.ICD9_diag_ty + CONVERT(VARCHAR(10),DIAGNOSIS_TABLE.ICD9_rank_no))='P1' then CODING_TABLE.icd9_code END P1,
CASE WHEN (DIAGNOSIS_TABLE.ICD9_diag_ty + CONVERT(VARCHAR(10),DIAGNOSIS_TABLE.ICD9_rank_no))='S2' then CODING_TABLE.icd9_code END S2,
CASE WHEN (DIAGNOSIS_TABLE.ICD9_diag_ty + CONVERT(VARCHAR(10),DIAGNOSIS_TABLE.ICD9_rank_no))='S3' then CODING_TABLE.icd9_code END S3
FROM         BILL_TABLE INNER JOIN
             PATIENT_TABLE ON BILL_TABLE.vst_int_id = PATIENT_TABLE.[Visit #] INNER JOIN
             PERSON_TABLE ON PATIENT_TABLE.psn_int_id = PERSON_TABLE.psn_int_id LEFT OUTER JOIN
             LOCATION_TABLE ON PATIENT_TABLE.loc_lvl_5_id = LOCATION_TABLE.loc_int_id LEFT OUTER JOIN
             DIAGNOSIS_TABLE ON PATIENT_TABLE.[Visit #] = DIAGNOSIS_TABLE.vst_int_id LEFT OUTER JOIN
             CODING_TABLE ON DIAGNOSIS_TABLE.icd9_int_id = CODING_TABLE.icd9_int_id

WHERE  (bil_cre_dt >= @BeginDateTime) AND 
    bil_cre_dt < @EndDateTime AND
    srvc_cd_int_id IN (20329, 21912, 20332, 20333, 20335, 20337, 20339, 20340, 20341, 20343) AND
    DIAGNOSIS_TABLE.ICD9_diag_ty != 'A'

我有一个想法可以帮助你解决这个问题。

您的结果数据

select * into #Result from
(
select '09/20/2017'DischargeDate  ,'12345' MedRec ,'111100' VisitID ,'203' Location ,'TESTER' LastName ,'JEFF' FirstName ,'01/01/1984'  DOB    ,'90210'  ZIP  ,'P1'DxRank ,'4005A'  Dx
union all
select '09/20/2017',  '12345',  '111100',    '203',  'TESTER',    'JEFF', '01/01/1984', '90210',   'S2', 'R42'
union all
select '09/20/2017',  '12345',  '111100',    '203',  'TESTER',    'JEFF', '01/01/1984', '90210',   'S3', 'E860'

)as a

静态查询

;with cte as (
select * from (
select MedRec,DxRank ,Dx from #result
)as b
pivot(max(Dx)for DxRank in([P1],[S2],[S3]) )as a
)
select distinct b.DischargeDate  , b.MedRec , b.VisitID , b.Location , b.LastName , b.FirstName ,b.DOB,[P1],[S2],[S3] from cte a
inner join 
(select DischargeDate  , MedRec , VisitID , Location , LastName , FirstName ,    DOB ,ZIP     from #Result)b
on b.MedRec=a.Medrec

动态查询

Declare @columns varchar(max)=stuff((select distinct ','+Dxrank from #result for xml path('')),1,1,'')
Declare @Query nvarchar(max)
set @Query=';with cte as (
select * from (
select MedRec,DxRank ,Dx from #result
)as b
pivot(max(Dx)for DxRank in('+@columns+') )as a
)
select distinct b.DischargeDate  , b.MedRec , b.VisitID , b.Location , b.LastName , b.FirstName ,    b.DOB,'+ @columns+  ' from cte a
inner join 
(select DischargeDate  , MedRec , VisitID , Location , LastName , FirstName ,    DOB      from #Result)b
on b.MedRec=a.Medrec'

print @Query
