SQL in Excel VBA - Best Practices

Wie verwende ich ADODB.Connection in VBA?

Bedarf:

Fügen Sie dem Projekt folgende Referenzen hinzu:

• Microsoft ActiveX Data Objects 2.8-Bibliothek

• Microsoft ActiveX Data Objects-Recordset 2.8-Bibliothek

Variablen deklarieren

Private mDataBase As New ADODB.Connection
Private mRS As New ADODB.Recordset
Private mCmd As New ADODB.Command

Verbindung herstellen

ein. mit Windows-Authentifizierung

Private Sub OpenConnection(pServer As String, pCatalog As String)
    Call mDataBase.Open("Provider=SQLOLEDB;Initial Catalog=" & pCatalog & ";Data Source=" & pServer & ";Integrated Security=SSPI")
    mCmd.ActiveConnection = mDataBase
End Sub

b. mit der SQL Server-Authentifizierung

Private Sub OpenConnection2(pServer As String, pCatalog As String, pUser As String, pPsw As String)
    Call mDataBase.Open("Provider=SQLOLEDB;Initial Catalog=" & pCatalog & ";Data Source=" & pServer & ";Integrated Security=SSPI;User ID=" & pUser & ";Password=" & pPsw)
    mCmd.ActiveConnection = mDataBase
End Sub

Führen Sie den SQL-Befehl aus

Private Sub ExecuteCmd(sql As String)
    mCmd.CommandText = sql
    Set mRS = mCmd.Execute
End Sub

Daten aus Datensatz lesen

Private Sub ReadRS()
    Do While Not (mRS.EOF)
        Debug.Print "ShipperID: " & mRS.Fields("ShipperID").Value & " CompanyName: " & mRS.Fields("CompanyName").Value & " Phone: " & mRS.Fields("Phone").Value
        Call mRS.MoveNext
    Loop
End Sub

Verbindung schließen

Private Sub CloseConnection()
    Call mDataBase.Close
    Set mRS = Nothing
    Set mCmd = Nothing
    Set mDataBase = Nothing
End Sub

Wie benutze ich es?

Public Sub Program()
    Call OpenConnection("ServerName", "NORTHWND")
    Call ExecuteCmd("INSERT INTO [NORTHWND].[dbo].[Shippers]([CompanyName],[Phone]) Values ('speedy shipping','(503) 555-1234')")
    Call ExecuteCmd("SELECT * FROM [NORTHWND].[dbo].[Shippers]")
    Call ReadRS
    Call CloseConnection
End Sub
