存储过程代码：

ALTER PROCEDURE [dbo].[startstoptime] 
    @employno varchar(5),
    @startdate datetime,
    @enddate datetime,
    @enddate2 datetime
AS
BEGIN
-- SET NOCOUNT ON added to prevent extra result sets from
-- interfering with SELECT statements.
SET NOCOUNT ON;
SET @enddate = DATEADD (d, 1, CAST(@startdate AS datetime));
SET @enddate2 = DATEADD (d, 7, CAST(@startdate AS datetime));
-- Insert statements for procedure here
SELECT DISTINCT B.EMPLOYNO, A.ACCOUNT_DAY,
                      (SELECT DISTINCT A.MARK_TIME
                        FROM          SYSADM.MARK AS A INNER JOIN
                                               SYSADM.PLACING AS C ON     A.PLAC_ID = C.PLAC_ID INNER JOIN
                                               SYSADM.STAFF_RESOURCE AS B ON B.RES_ID = C.RES_ID INNER JOIN
                                               SYSADM.ABSENCE AS D INNER JOIN
                                               SYSADM.ABSENCE_CAUSE AS E ON D.CAUSE_ID = E.CAUSE_ID ON C.PLAC_ID = D.PLAC_ID AND B.RES_ID = D.RES_ID
                        WHERE      (A.MARKTYPE = '1') AND (B.EMPLOYNO = @employno) AND (A.ACCOUNT_DAY >= CONVERT(DATETIME, @startdate, 102)) AND 
                                               (A.ACCOUNT_DAY < CONVERT(DATETIME, @endDate, 102)) AND (E.EXP_DESC IS NULL)) AS start,
                      (SELECT DISTINCT A.MARK_TIME
                        FROM          SYSADM.MARK AS A INNER JOIN
                                               SYSADM.PLACING AS C ON A.PLAC_ID = C.PLAC_ID INNER JOIN
                                               SYSADM.STAFF_RESOURCE AS B ON B.RES_ID = C.RES_ID INNER JOIN
                                               SYSADM.ABSENCE AS D INNER JOIN
                                               SYSADM.ABSENCE_CAUSE AS E ON D.CAUSE_ID = E.CAUSE_ID ON C.PLAC_ID = D.PLAC_ID AND B.RES_ID = D.RES_ID
                        WHERE      (A.MARKTYPE = '2') AND (B.EMPLOYNO = @employno) AND (A.ACCOUNT_DAY >= CONVERT(DATETIME, @startdate, 102)) AND 
                                               (A.ACCOUNT_DAY < CONVERT(DATETIME, @endDate, 102)) AND (E.EXP_DESC IS NULL)) AS stopp
FROM         SYSADM.MARK AS A INNER JOIN
                  SYSADM.PLACING AS C ON A.PLAC_ID = C.PLAC_ID INNER JOIN
                  SYSADM.STAFF_RESOURCE AS B ON B.RES_ID = C.RES_ID INNER JOIN
                  SYSADM.ABSENCE AS D INNER JOIN
                  SYSADM.ABSENCE_CAUSE AS E ON D.CAUSE_ID = E.CAUSE_ID ON C.PLAC_ID = D.PLAC_ID AND B.RES_ID = D.RES_ID
WHERE     (E.EXP_DESC IS NULL)
GROUP BY B.EMPLOYNO, A.ACCOUNT_DAY, A.MARK_TIME, E.EXP_DESC, A.MARKTYPE
HAVING      (B.EMPLOYNO = @employno) AND (A.ACCOUNT_DAY >= CONVERT(DATETIME, @startdate, 102)) AND (A.ACCOUNT_DAY < CONVERT(DATETIME, 
                  @endDate2, 102))
END

结果如下：

EMPLOYNO    |   ACCOUNT_DAY             |   start                   |   stop  
------------+---------------------------+---------------------------+---------------------------
03064       |   2015-02-05 00:00:00.000 |   2015-02-05 05:21:00.000 |   2015-02-05 14:15:00.000  
03064       |   2015-02-09 00:00:00.000 |   2015-02-05 05:21:00.000 |   2015-02-05 14:15:00.000  
03064       |   2015-02-11 00:00:00.000 |   2015-02-05 05:21:00.000 |   2015-02-05 14:15:00.000

启动和停止给出了错误的答案，因为我不知道如何在子查询中获取ACCOUNT_DAY而不是开始和停止日期，而不会得到多行的结果。

更改子查询中的查询值
