Hi,

Below is one of the query which was adviced from expert-exchange. This query really works fine if there is only one date in it. But, if there are multile dates then this query would fail to identify the oldest record for that day. I have attached the database for your reference. In the table named "LogInOutDetails" there are the following records with no data filled in for "LogOutTiming" column.

UserName                      LoginTiming                      LogOutTiming
Prashanth Prabhu      2/7/2012 10:45:47 AM
Prashanth Prabhu      2/8/2012 10:45:47 AM
Prashanth Prabhu      2/8/2012 1:47:19 PM

when I click on "Logout" button on form "PAUT" this query should update the current time for the record "2/8/2012 10:45:47 AM". But this query fails to do. Please advise.

Private Sub Command28_Click()

    Dim db As Database
    Dim rst As DAO.Recordset
    Set db = CurrentDb
    Dim Loginout As String
    Dim dblhour As Double
   
    Set rst = db.OpenRecordset("LogInOutDetails")    
           
    Dim sql As String
               
    sql = "UPDATE LogInOutDetails SET LogInOutDetails.LogoutTiming =  #" & Now() & "#" _
    & " WHERE (LogInOutDetails.UserName = '" & Forms!PAUT!Text15 & "') AND " _
    & "(LogInOutDetails.LoginTiming = #" & DMin("LoginTiming", "LogInOutDetails", "[UserName] = '" & [Forms]![PAUT]![Text15] & "'") & "# AND " _
    & " (nz(LogInOutDetails.LogoutTiming,0)=0) AND (DateValue([LogInOutDetails].[LoginTiming]))=#" & Date & "#)"
   
   
    DoCmd.SetWarnings False
    DoCmd.RunSQL sql
   
    DoCmd.Quit acQuitSaveAll
   
    End Sub
