Comparing array values

[riauvision]

Hello,
I have problem in writing ms Access vba code to compare two array taken from two different recordset. One is from table: Detail Orders (PK:[Details POID],POID,Product.Code,Qty) and the other is from table [Check-In Inventory] (PK:InventoryID, POID, ProductID.Code, Qty).

I retrive the [Detail Orders] and store its values in an array and also the [Check In Inventory] in another array.

My problem is How to compare the two arrays so that I can update the inventory?

My code :

 
Private Sub cmdUpdateStock_Click()
 
Dim rsOrdered As New ADODB.Recordset
Dim cnOrdered As New ADODB.Connection
Dim rsCheckedIn As ADODB.Recordset
Dim cnCheckedIn As ADODB.Connection
Dim StrSql
Dim arrOrdered As Variant
Dim arrCheckedIn As Variant
 
Set cnOrdered = CurrentProject.Connection
 
    StrSql = "SELECT [Q Detail Order].POID, [Q Detail Order].Code, " & _
             "[Q Detail Order].Qty FROM [Q Detail Order] " & _
             "WHERE ([Q Detail Order].POID) = " & Me.POID.Column(0) & "  "
    Set rsOrdered = cnOrdered.Execute(StrSql)
 
    If Not rsOrdered.EOF Then
        rsOrdered.MoveFirst
        Do While Not rsOrdered.EOF
            arrOrdered = rsOrdered.GetRows()
        If Not rsOrdered.EOF Then
            rsOrdered.MoveNext
        End If
        Loop
    End If
 
' retriver another recordset from [Check-In Inventory]
.
   arrCheckedIn = rsCheckedIn.GetRows()
 
'Comparing the two array's values
  < what code should i write?>
 
' clean up
    rsOrdered.Close
    cnOrdered.Close
    Set rsOrdered = Nothing
    Set cnOrdered = Nothing
    .
    .
    .
End Sub
 
 

Could you help me Please?

TQ in advance

Firstly, I would use DAO to do this instead of ADO.

 
Private Sub cmdUpdateStock_Click()
Dim db As DAO.Database 
Dim rsOrdered As DAO.Recordset
Dim rsCheckedIn As DAO.Recordset
Dim StrSql As String
Dim arrOrdered As Variant
Dim arrCheckedIn As Variant
 
Set db = CurrentDb
 
Set rsOrdered = db.OpenRecordset("Detail Orders")
Set rsCheckedIn = db.OpenRecordset("Check-In Inventory")
 
If Not rsOrdered.EOF And Not rs.Ordered.BOF Then
  rsOrdered.MoveFirst
  Do Until rsOrdered.EOF
    rsCheckedIn.FindFirst rsCheckedIn!POID=rsOrdered!POID
    If Not rsCheckedIn.NoMatch Then
      rsCheckedIn.Edit
      '<I don't know exactly what you want to do here>
      rsCheckedIn.Update
      Do Until rsCheckedIn.EOF
        rsCheckedIn.FindNext rsCheckedIn!POID=rsOrdered!POID
        If Not rsCheckedIn.NoMatch Then
          rsCheckedIn.Edit
          '<I don't know exactly what you want to do here> 
          rsCheckedIn.Update
        End If
      Loop
    End If
    rs.MoveNext
  Loop
End If
 
 
' clean up
rsOrdered.Close
rsCheckedIn.Close
Set rsOrdered = Nothing
Set rsCheckedIn = Nothing
Set db = Nothing
 
End Sub

Why would you use DAO instead of ADO? Isn't ADO is much more powerful than ADO according to Microsoft?
I want to compare those arrays so that if the goods arrived is less than what was ordered, it will then store the Qty Leg into QtlLeg Table together with the purchase Order number (POID) and other entities needed,

Else if it's equal, the inventory table will be updated.

Thx 4 ur Help.

Check out the following threads as they express it quite comprehensively. It is an ongoing hot argument but the conclusions of the MVP's who are essentially the Microsoft Approved experts is that DAO is the appropriate connection to use with the Jet Engine. In other words when using mdbs or mdes.
