我正在使用 SQL Server 2008。我想将三个不同的查询合并在一起，但由于查询的结构不同，我不确定如何正确执行。我的第一个查询创建了两个表来插入记录以进行比较，其中MAX返回访问列的 。前任：

询问：

SET ANSI_NULLS OFF
GO

-- VARIABLE DECLARATION
DECLARE @STARTDATE DATETIME
DECLARE @ENDDATE DATETIME

-- VARIABLE INITIALIZATION
SET @STARTDATE = '6/1/12';
SET @ENDDATE = '1/1/13';

--###########################################################################################
--## HERE IS WHERE WE DO TABLE COMPARISONS ##

SELECT
DISTINCT T1.ENCOUNTER,
T1.PT_NAME AS 'PT NAME', T1.MRN AS 'MRN', T1.LOS AS 'LOS', T1.PT_LOC AS 'PT LOC',
T1.PT_DISPO AS 'PT DISPO', T2.LAB_NAME2 AS 'LAB NAME', T2.LAB_VALUE2, T2.LOWER_LIMIT2 AS 'LOWER LIMIT',
T2.UPPER_LIMIT2 AS 'UPPER LIMIT', T2.AB_CODE2 AS 'AB CODE', T2.ORDER_ENTERED2

FROM @T1 T1
JOIN @T2 T2
ON T1.MRN = T2.MRN2

WHERE
T1.ENCOUNTER = T2.ENCOUNTER2
AND T1.ORDER_ENTERED < T2.ORDER_ENTERED2
AND T2.ORDER_ENTERED2 = (
                        SELECT MAX(TEMP.ORDER_ENTERED2)
                        FROM @T2 TEMP
                        WHERE T1.MRN = TEMP.MRN2
                        )

结果

CLIENT ID    VISIT ID     ARRIVE DATE     VALUE     DATE VALUE ORDERED
.......................................................................
1      |     1      |     1/1/13     |    5     |   1/1/13
1      |     1      |     1/1/13     |    6     |   1/2/13 <- returned row

此查询将返回日期值排序为 1/2/13 的行。

第二个查询计算了客户 ID 列中的客户在 12 个月的时间范围内出现了多少次。因此，对于上述内容，它将返回类似于查询 2 的内容：

-- VARIABLE DECLARATION
DECLARE @STARTDATE DATETIME
DECLARE @ENDDATE DATETIME

-- INITIALIZE VARIABLES
SET @STARTDATE = '6/1/12';
SET @ENDDATE = '1/1/13';

-- COLUMN SELECTION
SELECT DISTINCT CV.IDCode AS 'MRN', COUNT(CV.IDCODE) AS 'COUNT OF IP VISITS'

FROM CV3ClientVisit CV

WHERE CV.AdmitDtm BETWEEN @STARTDATE AND @ENDDATE
AND CV.TypeCode LIKE '%INPATIENT'
AND CV.VisitStatus IN(
'ADM',
'DSC'
)
GROUP BY CV.IDCode
ORDER BY COUNT(CV.IDCode) DESC

结果：客户 ID 访问次数 ................................................... 1 | 2

第三个也是最后一个查询告诉我他们做了多少次，例如

查询 3：

Declare @procedures Table (MRN varchar(20), Patient varchar(80), VisitID varchar(20), Admit datetime, Disch datetime, SurgProc varchar(200), ProcDesc varchar(200))
insert into @procedures


select cv.IDCode,cv.ClientDisplayName,cv.VisitIDCode,AdmitDtm,cv.DischargeDtm,ed.Description,ed.text from CV3ClientVisit cv
left join cV3ClientEventDeclaration ed
    on cv.GUID=ed.ClientVisitGUID
        where ed.typecode = 'Surgery'
        and cv.AdmitDtm > '6/30/12' and cv.AdmitDtm <='1/1/13'
        and Status = 'Active'

    select visitid, COUNT(visitid)as '#Surg Procs' from @procedures
        group by visitid

结果：

CLIENT ID     VISIT ID     ARRIVE DATE     DEPART DATE     COUNT OF PR VISITS
...............................................................................
1         |   1         |  1/1/13       |  1/3/13       |  3

所以我的问题是，我如何正确地JOIN将所有这些查询放在一起以获得一个结果？有时客户可能没有针对其中一个查询的结果。

我想最终的标题看起来像这样：

CLIENT ID | CLIENT VISIT ID | CLIENT NAME | LOS | PT LOC | PT DISPO | LAB NAME | LAB VALUE | LOWER LIMIT | UPPER LIMIT | AB CODE | COUNT OF IP VISITS | COUNT OF PROCEDURES

谢谢你

好的。我给你一个提示。

假设您有两种SELECT类型的查询。

第一次返回：Last Name, First Name, Date of Birth。

第二次回报：Last Name, First Name, Address, Occupation

您希望结果为：Last Name, First Name, Occupation, Date of Birth, Address

你会做这样的事情：

SELECT LastName, FirstName, NULL,      DOB,   NULL FROM ...
UNION
SELECT LastName, FirstName, Occupation, NULL, Address FROM ...
