好,所以我有一个电子表格可以产生大量记录(〜3500)
我有以下脚本将它们插入到我的Access数据库中:
Sub putinDB() Dim Cn As ADODB.Connection, Rs As ADODB.Recordset Dim MyConn, sSQL As String Dim Rw As Long, c As Long Dim MyField, Result Dim x As Integer Dim accName As String, AccNum As String, sector As String, holding As String, holdingvalue As Double, holdingdate As Date theend = lastRow("Holdings", 1) - 1 'Set source MyConn = "S:\Docs\Harry\Engine Client\Engine3.accdb" 'Create query Set r = Sheets("Holdings").Range("a2") x = 0 Do Application.StatusBar = "Inserting record " & x + 1 & " of " & theend accName = r.Offset(x, 0) AccNum = r.Offset(x, 4) sector = r.Offset(x, 2) holding = r.Offset(x, 1) holdingvalue = r.Offset(x, 3) holdingdate = r.Offset(x, 5) sSQL = "INSERT INTO Holdings (AccName, AccNum, Sector, Holding, HoldingValue, HoldingDate)" sSQL = sSQL & " VALUES ('" & Replace(accName, "'", "''") & "', '" & AccNum & "', '" & sector & "', '" & Replace(holding, "'", "''") & "', '" & holdingvalue & "', #" & holdingdate & "#)" Debug.Print (sSQL) 'Create RecordSet Set Cn = New ADODB.Connection With Cn .Provider = "Microsoft.ACE.OLEDB.12.0" .CursorLocation = adUseClient .Open MyConn Set Rs = .Execute(sSQL) End With x = x + 1 Loop While r.Offset(x, 0) <> "" Or x < 15 Application.StatusBar = False End Sub
问题是,它会一条一条地循环遍历每个记录,每次都重建并执行查询,这导致执行速度非常慢(在我的PC上每秒大约有2-3条记录)
有没有一种方法可以让vba一次性将整个范围插入数据库,而无需循环遍历?谢谢
好,我傻 经过一番修补后,事实证明
Set Cn = New ADODB.Connection With Cn .Provider = "Microsoft.ACE.OLEDB.12.0" .CursorLocation = adUseClient .Open MyConn End With
循环外的位使其更快。
