  Isn't there also supposed to be some "deleted" data to go along with that "added" data?

  RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
  First step towards the paradigm shift of writing Set Based code:
  ________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

  Change is inevitable... Change for the better is not.

  jeff,

  Sorry. Here is the delete data:

  --===== If the test table already exists, drop it

  IF OBJECT_ID('TempDB..#moncalldelete','U') IS NOT NULL

  DROP TABLE #moncalldelete

  --===== Create the test table with

  CREATE TABLE #moncalldelete

  (

  FIRSTLISTING NVARCHAR,

  StartOncallDate INT,

  StartOncallTime INT,

  Duration DECIMAL,

  Schedname NVARCHAR,

  AddTime INT,

  AddDate INT

  )

  --===== All Inserts into the IDENTITY column

  SET IDENTITY_INSERT #moncalldelete ON

  --===== Insert the test data into the test table

  INSERT INTO #mytable

  (ID, DateValue, Value, YearValue, Monthvalue)

  Jeff, (or anyone)

  Any word on this query?

  here's what I have now:

  SELECT FirstListing,OnCallStart,OnCallEnd

  FROM

  (

  SELECT

  moncallAdd.FirstListing,

  DATEADD(MINUTE, mOnCallAdd.StartOnCallTime,

  DATEADD(DAY, mOnCallAdd.StartOnCallDate, '12/31/1899')) AS OnCallStart,

  DATEADD(MINUTE, mOnCallAdd.duration,

  DATEADD(MINUTE, mOnCallAdd.StartOnCallTime,

  DATEADD(DAY, mOnCallAdd.StartOnCallDate, '12/31/1899'))) AS OnCallEnd,

  'Added' as Activity

  FROM

  mdr.dbo.mOnCallAdd

  WHERE DATEADD(MINUTE, mOnCalladd.StartOnCallTime,

  DATEADD(DAY, mOnCalladd.StartOnCallDate, '12/31/1899')) < GETDATE()

  AND

  DATEADD(MINUTE, mOnCalladd.duration,

  DATEADD(MINUTE, mOnCalladd.StartOnCallTime,

  DATEADD(DAY, mOnCalladd.StartOnCallDate, '12/31/1899'))) > GETDATE() and

  mOnCallAdd.SchedName = 'capital neph'

  UNION

  SELECT

  moncallDelete.FirstListing,

  DATEADD(MINUTE, mOnCallDelete.StartOnCallTime,

  DATEADD(DAY, mOnCallDelete.StartOnCallDate, '12/31/1899')) AS OnCallStart,

  DATEADD(MINUTE, mOnCallDelete.duration,

  DATEADD(MINUTE, mOnCallDelete.StartOnCallTime,

  DATEADD(DAY, mOnCallDelete.StartOnCallDate, '12/31/1899'))) AS OnCallEnd,

  'Deleted' as Activity

  FROM

  mdr.dbo.mOnCallDelete

  WHERE DATEADD(MINUTE, mOnCallDelete.StartOnCallTime,

  DATEADD(DAY, mOnCallDelete.StartOnCallDate, '12/31/1899')) < GETDATE()

  AND

  DATEADD(MINUTE, mOnCallDelete.duration,

  DATEADD(MINUTE, mOnCallDelete.StartOnCallTime,

  DATEADD(DAY, mOnCallDelete.StartOnCallDate, '12/31/1899'))) > GETDATE() and

  mOnCallDelete.SchedName ='capital neph'

  )t

  GROUP BY FirstListing,OnCallStart,OnCallEnd

  HAVING SUM(CASE WHEN Activity='Added' THEN 1 ELSE 0 END) >0

  AND SUM(CASE WHEN Activity='Deleted' THEN 1 ELSE 0 END) =0

  and when I run that .. I get the following dataset:

  The second set of data has the "complete" set of data but that's been filtered.You can see the difference between the two queries that I ran so the second query gives me ALL data, both adds and deletes. The other query only gives me the "adds" that don't have a matching delete, but obviously it's not catching all of that information. As you can see, the second dataset's first two entries aren't in the first dataset.

  Can anyone help me figure out why?
