Post by sal21 »

Code: Select all

Option Explicit
Public Sub APRI_CON_DBF()
    
    Dim strCnString As String
    Set CON = New ADODB.Connection
    strCnString = "Driver={Microsoft Visual FoxPro Driver};UID=;SourceDB=" & SBASE & ";SourceType=DBF;Exclusive=No;BackgroundFetch=Yes;Collate=Machine"
    CON.Open strCnString
    
End Sub
Sub UNO()
    
    If CON Is Nothing Then
        Call APRI_CON_DBF
    End If
    
    Dim STRDBROWS() As Variant, I As Long
    
    Set RS = New ADODB.Recordset
    SQL = "SELECT AB, AC, AD, AEFROM " & NOME_DBF & " WHERE NOT DATATT IS NULL ORDER BY AB DESC"
    RS.Open SQL, CON, adOpenForwardOnly, adLockReadOnly ', adOpenKeyset, adLockPessimistic
    
    'I = RS.RecordCount
    
    RS.MoveFirst
    Erase STRDBROWS()
    STRDBROWS = RS.GetRows()
    RS.Close
    Set RS = Nothing
    
End Sub

Does it work if you use

WHERE DATATT IS NOT NULL

I would guess that if DATTAT is NULL then Not DATATT will also be NULL
