我自己用的导入保存 第一个参数是原数据表 第二个参数是目的数据表 参考lsy先前的一个帖子做的
导入的时候先生成一个临时表把数据倒进去，然后使用多行一次性插入保存 速度比save快多了 我使用互联网保存500条数据 37列 大概是16-20秒
Dim stbl As String = Args(0)
Dim dtbl As String = Args(1)
Dim dt As Date = Date.Now
Dim cmd As New SQLCommand
cmd.C
Dim sql1,sql2 As String
For Each c As Col In Tables(stbl).Cols
sql1 + = c.Name & ","
Next
For Each r As Row In Tables(stbl).Rows
sql2 = ""
For Each c As Col In Tables(stbl).Cols
If c.IsDate Then
sql2 + = "'" & r(c.Name) & "'" & ","
ElseIf c.IsString Then
sql2 + = "'" & r(c.Name) & "',"
ElseIf c.IsBoolean Then
If r(c.Name) = True Then
sql2 + = 1 & ","
ElseIf r(c.Name) = False Then
sql2 + = 0 & ","
End If
Else
sql2 + = r(c.Name) & ","
End If
Next
cmd.CommandText + = "InSert Into " & dtbl & " (" & sql1.Trim(",") & ") Values (" & sql2.Trim(",") & ");"
Next
cmd.CommandText = cmd.CommandText.Trim(";")
cmd.ExecuteNonQuery
DataTables(dtbl).Load
Dim tp As TimeSpan
tp = Date.Now - dt
MessageBox.Show(tp.TotalSeconds)
