  Hello and Thanks for looking at this,

  I am not a developer, so my apologies if my information is provided incorrectly. I will try to be as thorough as possible.

  Platform: SQL Server Express 2008 R2 with Tools / Windows 7 Home Premium (64-Bit)

  I have a small project that requires a SQL Script to retrieve Time and Attendance with Total Number of Hours for a single day.

  (Rules)

  I need to show the 1st Clock In and the Last Clock Out for each day, then Calculate Total Number of Hours

  -- ***********************************************

  -- Notice that the Clock In should be 07:36:00 not 12:07:00

  -- This would also get me to the correct Hours Worked

  -- ***********************************************

  I have a three row table "Sampling" as displayed below.

  -- ==== Create and Populate 3 Row Test_Table with Sample Data

  CREATE TABLE [Test_Table]

  ( [ID] INT IDENTITY(1,1) PRIMARY KEY CLUSTERED -- PK

  , [Date] [smalldatetime] NOT NULL -- Date using SmallDateTime Type YYYY-MM-DD HH:MM:00

  , [Employee Number] [varchar](50) NOT NULL -- Employee can contain alphanumeric

  , [Clock In or Out] [varchar](50) NOT NULL ) -- Record Type; "Clock In" or "Clock Out" Record Only

  SET DATEFORMAT DMY

  SET IDENTITY_INSERT [Test_Table] ON

  INSERT INTO [Test_Table]

  ( [ID]

  , [Date]

  , [Employee Number]

  , [Clock In or Out] )

  SELECT '3','Oct 5 2012 7:36AM','AD101','Clock In' UNION ALL

  SELECT '4','Oct 5 2012 12:05PM','AD101','Clock Out' UNION ALL

  SELECT '5','Oct 5 2012 12:07PM','AD101','Clock In'

  -- ==== End Create and Populate

  Here is a full table query.

  -- ***********************************************

  -- Select ALL from Test_Table

  -- ***********************************************

  SELECT [ID]

  , [Date]

  , [Employee Number]

  , [Clock In or Out]

  FROM [Test_Table]

  ORDER BY [Date]

  On this day, there were two "Clock In" and only one "Clock Out" record in the Test_Table

  IDDateEmployee NumberClock In or Out

  ------------------------------------------------------

  32012-10-05 07:36:00AD101Clock In

  42012-10-05 12:05:00AD101Clock Out

  52012-10-05 12:07:00AD101Clock In

  I used some of the code in another FORUM Posting pertaining to Clock In and Clock Out to get to this point.

  It works great as long as there is only ONE Clock In and ONE Clock Out Record for a day.

  But if there happens to be more than ONE of either, that's when the output is incorrect.

  -- ***********************************************

  -- Select from Test_Table with conditions

  -- ***********************************************

  SELECT [Employee Number]

  , [Clock In]

  , [Clock Out]

  , (CASE WHEN CAST([Clock In] as SmallDateTime) = '1900-01-01 00:00:00'

  THEN ''

  WHEN CAST([Clock Out] as SmallDateTime) = '1900-01-01 00:00:00'

  THEN ''

  WHEN CAST([Clock In] as SmallDateTime) < CAST([Clock Out] as SmallDateTime)

  THEN CAST(CONVERT(DECIMAL,DATEDIFF(MINUTE,CAST([Clock In] as SmallDateTime),CAST([Clock Out] as SmallDateTime)))/60 as Varchar)

  ELSE '' END) [Hours Worked]

  FROM (

  SELECT [Employee Number]

  , MAX(CASE WHEN [Clock In or Out] = 'Clock In' -- I believe this is the area where I am having the problem

  THEN CAST([Date] as SmallDateTime) -- I have tried MIN(CASE WHEN... but that does not seem to work for me either

  ELSE '' END) [Clock In]

  , MAX(CASE WHEN [Clock In or Out] = 'Clock Out'

  THEN CAST([Date] as SmallDateTime)

  ELSE '' END) [Clock Out]

  FROM (

  SELECT [Employee Number]

  , [Clock In or Out]

  , CAST(CONVERT(VARCHAR(10),[Date],111) as Date) [Clock In or Out Date]

  , [Date]

  FROM [Test_Table]

  ) TableA

  GROUP BY [Employee Number]

  , [Clock In or Out Date]

  ) TableB

  -- ***********************************************

  -- Output is not what I was trying for.

  -- Notice that the Clock In Time is 12:07:00

  -- I need it to be the other record which is 07:36:00

  Good job on the test data and description...:-D

  SELECT

  [Employee Number],

  X.[Dated],

  MIN(CASE [Clock In or Out] WHEN 'Clock In' THEN CONVERT(DATETIME,[Date]) ELSE CONVERT(DATETIME,'31 dec 2199') END) AS [Clock In],

  MAX(CASE [Clock In or Out] WHEN 'Clock In' THEN 0 ELSE [Date] END) AS [Clock Out]

  FROM [Test_Table]

  CROSS APPLY (

  -- This just works out the date part without the time

  SELECT DATEADD(DAY,datediff(DAY,0,[Date]),0) AS [Dated]

  ) AS X

  GROUP BY

  [Employee Number],

  X.[Dated]
