Joining on a field with different values I am trying to join data from two completely different sources. One source contains an employee's schedule information, and the other tracks what they actually worked (like what time they actually took lunch or break). The problem is, the schedule program gives times as BREAK1, BREAK2, BREAK3, and LUNCH, while the tracking program simply lists them as Lunch and Break. I can join the data and get the lunches just fine, but the breaks are throwing me off. If I convert BREAK1, BREAK2, and BREAK3 to just "Break", I end up with too many segments because it is matching every instance with every other instance. Is there a way that anyone can think of to join these two pieces of information?

Here is some sample data:

This is the Scheduled Times:

EMP_ID  NOM_DATE    SEG_CODE    START_MOMENT    STOP_MOMENT
626009  26-Sep-13   BREAK2          9/26/13 5:00 PM 9/26/13 5:15 PM

This is the Actual Times

621649  Lunch           9/26/2013 12:31 9/26/2013 13:30


I am trying to get the difference (in minutes) between when they are scheduled, and when they are actually taking breaks. A correct example is:

Badge   Seg_Code    Scheduled Start     Scheduled Stop      Actual Start           Actual Stop      Difference      Seg_Duration
192329  Lunch       9/26/13 8:15 AM     9/26/13 9:15 AM     9/26/2013 8:18:27 AM    9/26/2013 9:17:59 AM        3       0:00:59:32


Thank you
EDIT with updated code: 

Try something like this.  The idea is to order actual breaks by time and then append the cardinal row_number to 'BREAK' so that it joins wtih BREAK1, BREAK2, etc.

CREATE TABLE #Scheduled
(Emp_ID int, NOM_DATE DATE,  SEG_CODE varchar(10),    START_MOMENT Datetime,   STOP_MOMENT Datetime);

INSERT INTO #Scheduled VALUES(626009  ,'26-Sep-13',   'BREAK2',          '9/26/13 5:00 PM', '9/26/13 5:15 PM');
INSERT INTO #Scheduled VALUES(625650  ,'26-Sep-13',   'BREAK2',          '9/26/13 4:30 PM', '9/26/13 4:45 PM');
INSERT INTO #Scheduled VALUES(638815  ,'26-Sep-13',   'BREAK2',          '9/26/13 4:00 PM', '9/26/13 4:15 PM');

Then here is some code to get the answer.  I handled (after a fashion) unscheduled breaks as well.  See:

   SELECT COALESCE(s.Emp_ID,a.EMP_ID) AS 'Badge', COALESCE(s.Seg_Code, a.CalcSeg, 'Unscheduled') AS Seg_Code,
           s.START_MOMENT AS 'Schedule Start', s.STOP_MOMENT AS 'Scheduled Stop',
           a.Start_Time AS 'Actual Start', a.Stop_Time AS 'Actual Stop'
    FROM #Scheduled s
        FULL OUTER JOIN 
             (SELECT Emp_ID,
               CASE
                 WHEN Seg_Code = 'Break' THEN Seg_Code + 
                     CAST(ROW_NUMBER() OVER (PARTITION BY Emp_ID, Seg_Code ORDER BY Start_Time) as CHAR(2))
                 ELSE Seg_Code 
               END AS CalcSeg,
               Start_Time, Stop_Time
              FROM #Actual) AS a
        ON s.EMP_ID = a.Emp_Id
           AND s.Seg_Code = a.CalcSeg
           AND s.NOM_DATE = CAST(a.Start_Time AS DATE)
        ORDER BY Badge, COALESCE(s.Start_Moment, a.Start_Time), SEG_CODE;

    DROP TABLE #Scheduled;
    DROP TABLE #Actual;


That seems to be what you were after.
