Excel VBA访问

Question

I have the following code, where .Fields... is not getting executed. Loop is directly closing the connection without adding records into table.

Code:

Sub insertIntoTable()

    Dim moviesConn As ADODB.Connection
    Dim moviesData As ADODB.Recordset
    Dim moviesField As ADODB.Fields
    Dim r As Range

    Set moviesConn = New ADODB.Connection
    Set moviesData = New ADODB.Recordset

    moviesConn.ConnectionString = conStrAccess
    moviesConn.Open

    On Error GoTo closeConnection

    With moviesData
        .ActiveConnection = moviesConn
        .Source = "tblFilmDetails"
        .LockType = adLockOptimistic
        .CursorType = adOpenForwardOnly
        .Open

    On Error GoTo closeRecordset
        For Each r In Range("A3", Range("A2").End(xlDown))
            .AddNew
            .Fields("Title").Value = r.Offset(0, 1).Value
            .Fields("Release_Date").Value = r.Offset(0, 2).Value
            .Fields("Length").Value = r.Offset(0, 3).Value
            .Fields("Genere").Value = r.Offset(0, 4).Value
            .Update
        Next r
    End With

    closeRecordset:
    moviesData.Close

    closeConnection:
    moviesConn.Close

End Sub

Please suggest

I was able to get your code to work using this connection string:

"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\\Users\\best buy\\Desktop\\test.accdb;Persist Security Info=False;"

We can rule out data mismatch error because it throws a 3219 Runtime Error Operation before closing the connection.

Range("A3", Range("A2").End(xlDown)) should probably be changed Range("A2", Range("A" & Rows.Count).End(xlup)) for two reasons:

1. It skips row 2
2. If there is no data beyond row 2 you will add 1048575 empty records (Ask me how I know)

If you have a large dataset you should comment out .Update and use .UpdateBatch after you have added all the records. This will greatly improve performance.

    For Each r In Range("A3", Range("A2").End(xlDown))
        .AddNew
        .Fields("Title").Value = r.Offset(0, 1).Value
        .Fields("Release_Date").Value = r.Offset(0, 2).Value
        .Fields("Length").Value = r.Offset(0, 3).Value
        .Fields("Genere").Value = r.Offset(0, 4).Value
        '.Update
    Next r
    .UpdateBatch

Note: If you have the table open while adding the records then you have to press F5 to refresh the table and view the new data.
