Problem with WHERE in SQL only in code

Hi Everyone, Thanks ahead of time for the help.

My Code:

Code:

    Private Sub btnExport_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnExport.Click
        Dim Conn As New ADODB.Connection
        Dim Rec As New ADODB.Recordset
        Dim SQLqry As String

        On Error GoTo btnExport_Error

        'Build SQL Query
        SQLqry = "SELECT     ClockData.[Date], Employee.FirstName, Employee.LastName, ClockData.TimeIn, ClockData.TimeOut, ClockData.Comment" & _
                 " FROM (Employee INNER JOIN ClockData ON ClockData.EmployeeNumber = Employee.EmployeeNumber)" & _
                 " WHERE (ClockData.[Date] <= #4/2/2009#) AND (ClockData.[Date] >= #4/1/2009#) AND (Employee.FirstName = 'Shai')"

        Debug.Print(SQLqry)
        'Open connection to database delared on Form1_Activated
        Conn.ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data source=" & dbPath & " ;Persist Security Info=True;User ID=admin;Jet OLEDB:Database Password=twinvolcano"
        Conn.Open()
        Rec.Open(SQLqry, Conn, ADODB.CursorTypeEnum.adOpenDynamic, ADODB.LockTypeEnum.adLockPessimistic)
        'Go through records
        While Not Rec.EOF
            'Do Something with records
            Debug.Print(Rec.Fields("FirstName").Value)
            'Goto next record in recordset
            Rec.MoveNext()
        End While

        'Close database connections
        Rec.Close()
        Conn.Close()

        Exit Sub
btnExport_Error:
        ' Describe the error to the user.
        MsgBox("Unexpected error" & _
            Str$(Err.Number) & _
            " in subroutine DoSomething." & _
            vbCrLf & _
            Err.Description)
        Exit Sub


    End Sub

I can take the debug.print(SQLqry) output

Code:

SELECT     ClockData.[Date], Employee.FirstName, Employee.LastName, ClockData.TimeIn, ClockData.TimeOut, ClockData.Comment FROM (Employee INNER JOIN ClockData ON ClockData.EmployeeNumber = Employee.EmployeeNumber) WHERE (Employee.FirstName = 'Shai')

from the immediate window, put it in the VB query designer and it returns results:
Snippete of results:

Code:

10/15/2008 12:00:00 AM    Shai    Perednik    10/15/2008 1:05:00 PM    10/15/2008 6:18:00 PM    NULL
10/16/2008 12:00:00 AM    Shai    Perednik    10/16/2008 7:57:00 AM    10/16/2008 12:34:00 PM    NULL

10/17/2008 12:00:00 AM    Shai    Perednik    10/17/2008 7:53:00 AM    10/17/2008 10:01:04 AM    NULL
10/17/2008 12:00:00 AM    Shai    Perednik    10/17/2008 10:09:11 AM    10/17/2008 12:24:00 PM    NULL
10/17/2008 12:00:00 AM    Shai    Perednik    10/17/2008 2:54:00 PM    10/17/2008 5:03:00 PM    NULL
10/20/2008 12:00:00 AM    Shai    Perednik    10/20/2008 7:41:00 AM    10/20/2008 12:29:00 PM    NULL
10/20/2008 12:00:00 AM    Shai    Perednik    10/20/2008 1:10:00 PM    10/20/2008 5:22:00 PM    NULL
10/21/2008 12:00:00 AM    Shai    Perednik    10/21/2008 7:46:00 AM    10/21/2008 12:46:42 PM    NULL

BUT, in code, watching the locals window for rec.EOF and rec.BOF both return true and therefore no results.

So whats wrong? Why does this work in VB Query Designer but not in code?

If I remove the WHERE statement than the results return fine as expected. But its returning ALL of the results which is no good.

HUH??? I do *NOT* believe that this query:

Code:

SELECT ClockData.[Date], Employee.FirstName, Employee.LastName, ClockData.TimeIn, ClockData.TimeOut, ClockData.Comment 
FROM (Employee INNER JOIN ClockData ON ClockData.EmployeeNumber = Employee.EmployeeNumber) 
WHERE (Employee.FirstName = 'Shai')

Results from the
Debug.Print(SQLqry)
of this code:

Code:

SQLqry = "SELECT     ClockData.[Date], Employee.FirstName, Employee.LastName, ClockData.TimeIn, ClockData.TimeOut, ClockData.Comment" & _
                 " FROM (Employee INNER JOIN ClockData ON ClockData.EmployeeNumber = Employee.EmployeeNumber)" & _
                 " WHERE (ClockData.[Date] <= #4/2/2009#) AND (ClockData.[Date] >= #4/1/2009#) AND (Employee.FirstName = 'Shai')"

...

What happened to the text in RED there???

You must be looking at OLD debug output, not the current code.

By the way, that WHERE clause as written will *ONLY* find records where ClockData.Date is between April 1, 2009, Midnight and April 2, 2009, Midnight. Is that what you really wanted???

Go and have a look at the MySQL website they have some good controls you can use!
