    I'm a database newby and I need a little help

    I have an access database with the following fields:

    ID, ParentID, Level

    Level and ParentID are filled with numbers Level is filled with zero's.

    I want to have a loop that looks at every record an checks if the ID of that record matches a ParentID in any of te other records if this is the case the Level field of that record should be set to 1

    Can anybody help me with this please ?

    Did som studying :-)

    Here's my solution in case you would hate me for not sharing...

    Code:
    Dim db As Database
    Dim rs As Recordset
    Dim rs2 As Recordset
    Dim iValue As Integer
    Dim iCounter As Integer
    
        'open database
        Set db = DBEngine.OpenDatabase(App.Path & "\4_new.mdb")
        'open recordset using SQL
        Set rs = db.OpenRecordset("Select * from Menu")
        Set rs2 = db.OpenRecordset("Select * from Menu")
        
        
        i = 1
        Do Until rs.EOF = True
        i = i + 1
                'rs.Fields("Name").Valu
                iValue = rs.Fields("ID").Value
                Do Until rs2.EOF = True
                    If rs2.Fields("ParentID").Value = iValue Then
                        rs.Edit
                        rs.Fields("submenu").Value = 1
                        rs.Update
                    End If
                    rs2.MoveNext
                    DoEvents
                Loop
                rs2.MoveFirst
                rs.MoveNext
                Label1.Caption = i
        DoEvents
        Loop
        
            
       
        
        
        'close db/rs
        rs.Close
        rs2.Close
        db.Close
        Set rs = Nothing
        Set db = Nothing
        Label1.Caption = "Done..."

    Why all the hard coding stuff?

    Execute this SQL query:
    "UPDATE Menu INNER JOIN Menu AS Menu_1 ON Menu.ID = Menu_1.ParentID SET Menu.[Level] = 1;"
