Sql server SQL Server 2008快速查询,sql-server,sql-server-2008-express,Sql Server,Sql Server 2008 Express,我无法使以下查询正常工作： SELECT tblEmployees.iEmployeeNum AS ID, tblEmployees.tLastName AS SURNAME, tblEmployees.tFirstName AS NAME, pInt.dtEventReal AS 'ENTRANCE', pIes.dtEventReal AS 'EXIT' FROM tblEmployees LEFT JOIN (SELECT DISTINCT d

我无法使以下查询正常工作：

SELECT  
   tblEmployees.iEmployeeNum AS ID, tblEmployees.tLastName AS SURNAME, tblEmployees.tFirstName AS NAME,
   pInt.dtEventReal AS 'ENTRANCE', pIes.dtEventReal AS 'EXIT'
FROM 
   tblEmployees
LEFT JOIN
   (SELECT DISTINCT 
       dtEventReal,idEmpNum 
   FROM 
       tblEvents 
   WHERE
       tDesc LIKE '%Entrance%' 
       AND CAST(tblEvents.dtEventReal AS DATE) BETWEEN CAST('2014-07-07' AS DATE) AND CAST('2014-07-08' AS DATE) 
   ) AS pInt ON pInt.idEmpNum = tblEmployees.iEmployeeNum
LEFT JOIN
   (SELECT DISTINCT 
       dtEventReal, idEmpNum 
    FROM 
       tblEvents 
    WHERE
       tDesc LIKE '%Exit%' 
       AND CAST(tblEvents.dtEventReal AS DATE) BETWEEN CAST('2014-07-07' AS DATE) AND CAST('2014-07-08' AS DATE) 
   ) AS pIes ON pIes.idEmpNum = tblEmployees.iEmployeeNum
WHERE 
   iEmployeeNum = 265 
   AND (CAST(pInt.dtEventReal AS DATE) = CAST(pIes.dtEventReal AS DATE) 
        OR (DATEPART(hh, pInt.dtEventReal) >= 18 
            AND CAST(pInt.dtEventReal AS DATE date) = CAST(pIes.dtEventReal-1 AS DATE)))

我得到的结果是：

ID  SURNAME   NAME        ENTRANCE                  EXIT
265 LAST    FIRST   2014-07-07 07:56:08.000 2014-07-07 10:21:34.000
265 LAST    FIRST   2014-07-07 15:12:17.000 2014-07-07 10:21:34.000
265 LAST    FIRST   2014-07-07 07:56:08.000 2014-07-07 16:47:31.000
265 LAST    FIRST   2014-07-07 15:12:17.000 2014-07-07 16:47:31.000
265 LAST    FIRST   2014-07-08 07:56:34.000 2014-07-08 10:05:39.000
265 LAST    FIRST   2014-07-08 14:32:53.000 2014-07-08 10:05:39.000
265 LAST    FIRST   2014-07-08 07:56:34.000 2014-07-08 16:46:35.000
265 LAST    FIRST   2014-07-08 14:32:53.000 2014-07-08 16:46:35.000

我要找的是：

ID  NAME    SURNAME      ENTRANCE                  EXIT
265 LAST    FIRST   2014-07-07 07:56:08.000 2014-07-07 10:21:34.000
265 LAST    FIRST   2014-07-07 15:12:17.000 2014-07-07 16:47:31.000
265 LAST    FIRST   2014-07-08 07:56:34.000 2014-07-08 10:05:39.000
265 LAST    FIRST   2014-07-08 14:32:53.000 2014-07-08 16:46:35.000

L.E.1-最后一个条件存在

OR
(datepart(hh,pInt.dtEventReal)>=18 and cast(pInt.dtEventReal as date)=cast(pIes.dtEventReal-1 as date)))

因为我们有人上夜班，第二天早上就下班了

L.E.2-

通过从控制器获取事件的软件自动将事件添加到数据库：

IdAutoEvents tDesc          dtEventReal           tLastName tFirstName   iEmployeeNum
    312503  Main_Entrance   2014-07-18 07:24:33.000 SURNAME NAME            265
    312742  Main_Exit   2014-07-18 10:31:23.000 SURNAME NAME            265

L.E 3-基于mxix答案的最终版本：

SELECT  
    E.iEmployeeNum ID, 
    E.tLastName SURNAME, 
    E.tFirstName NAME,
    pInt.dtEventReal AS 'ENTRANCE', 
    pIes.dtEventReal AS 'EXIT',
    pInt.tDesc AS 'Entrance Location', 
    pIes.tDesc AS 'Exit Location'
FROM tblEmployees E
LEFT JOIN (
    SELECT 
        DISTINCT 
        dtEventReal,
        idEmpNum,
                tDesc
    FROM tblEvents 
    WHERE
       tDesc LIKE '%Entrance%' AND 
       CONVERT(DATE,tblEvents.dtEventReal) BETWEEN cast('2014-07-07' as date) AND cast('2014-07-12' as date)
) pInt ON 
    pInt.idEmpNum = E.iEmployeeNum
OUTER APPLY(
    SELECT 
        TOP 1
        dtEventReal, 
        idEmpNum,
                tDesc
    FROM tblEvents Ev
    WHERE
       tDesc LIKE '%Exit%' AND
       Ev.idEmpNum = pInt.idEmpNum and
       pInt.dtEventReal < Ev.dtEventReal
    ORDER BY
        dtEventReal ASC
   ) AS pIes
WHERE 
        E.IdDepartment in (2,11)
        ORDER BY E.tLastName ASC, E.tFirstName, pInt.dtEventReal

试试看

   DECLARE 
    @start DATE = '2014-07-07',
    @end DATE = '2014-07-07',
    @user_id int = 265;

SELECT  
   E.iEmployeeNum ID, 
   E.tLastName SURNAME, 
   E.tFirstName NAME,
   pInt.dtEventReal AS 'ENTRANCE', 
   pIes.dtEventReal AS 'EXIT'
FROM tblEmployees E
LEFT JOIN (
    SELECT 
        DISTINCT 
        dtEventReal,
        idEmpNum 
    FROM tblEvents 
    WHERE
       tDesc LIKE '%Entrance%' AND 
       CONVERT(DATE,tblEvents.dtEventReal) BETWEEN @start AND @end
) pInt ON 
    pInt.idEmpNum = E.iEmployeeNum
OUTER APPLY(
    SELECT 
        TOP 1
        dtEventReal, 
        idEmpNum 
    FROM tblEvents Ev
    WHERE
       tDesc LIKE '%Exit%' AND
       Ev.idEmpNum = pInt.idEmpNum and
       pInt.dtEventReal > Ev.dtEventReal
    ORDER BY
        dt_EventReal ASC
   ) AS pIes
WHERE 
    E.iEmployeeNum = @user_id

哎呀，我误读了几行。很抱歉。你能解释一下你要找的图案吗？如何从第一个结果集获得第二个结果集？我添加了更多的信息，并做了一些修改，效果非常好，我在最终版本下面发布了。出于某种原因，我声明它不起作用，所以我又切换回cast作为开始和结束日期。另外，这是一个输入错误，pInt.dtEventReal>Ev.dtEventReal应该是pInt.dtEventReal
