System.Data.OleDb.OleDbException无效参数

Question

我正在上传一个Excel工作表，并希望将其数据移动到数据库中的另一个表中。 最近两天，我一直收到一个错误（ System.Data.OleDb.OleDbException invalid argument ），但是，如果我设计一个非常简单的应用程序，则可以正常工作。 请帮我

Using conn As New SqlConnection(ConfigurationManager.ConnectionStrings("TERAMSConnectionString").ConnectionString)
            Dim path As String = FileUpload1.PostedFile.FileName
            Dim excelConnectionString As String = ("Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + (path + ";Extended Properties=Excel 12.0;Persist Security Info=False"))
            Dim excelConnection As OleDbConnection = New OleDbConnection(excelConnectionString)
            conn.Open()
            excelConnection.Open()
            Dim cmd As OleDbCommand = New OleDbCommand("Select * from [Sheet1$]", excelConnection)
            'Clears any previous data
            Dim sClearSQL = "DELETE FROM Desktop_Compare "
            Dim SqlCmd As SqlCommand = New SqlCommand(sClearSQL, conn)
            SqlCmd.ExecuteNonQuery()
            Dim dReader As OleDbDataReader = cmd.ExecuteReader
            Dim sqlBulk As SqlBulkCopy = New SqlBulkCopy(conn)
            excelConnection.Close()
            conn.Close()
        End Using


Line 74:             Dim excelConnection As OleDbConnection = New OleDbConnection(excelConnectionString)
Line 75:             conn.Open()
Line 76:             **excelConnection.Open()**
Line 77:             Dim cmd As OleDbCommand = New OleDbCommand("Select * from [Sheet1$]", excelConnection)
Line 78:             'Clears any previous data

Answer 1

尝试将您的连接字符串更改为：

Dim excelConnectionString As String = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & path & ";"

如果这不起作用，请尝试一次更改/添加Extended Properties和Persist Security Info ，因为这可能是ACE驱动程序出现问题，或者是其他参数之一引起了问题

至于您的用户遇到未处理的错误，您可以尝试执行以下操作：

        Dim excelConnectionString As String = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & path & ";"

        Using excelConnection As OleDb.OleDbConnection = New OleDb.OleDbConnection(excelConnectionString)
            Try
                excelConnection.Open()

                Using cmd As OleDb.OleDbCommand = New OleDb.OleDbCommand("Select * from [Sheet1$]", excelConnection)

                    'Clears any previous data
                    Dim sClearSQL As String = "DELETE FROM Desktop_Compare "
                    Using SqlCmd As SqlClient.SqlCommand = New SqlClient.SqlCommand(sClearSQL, conn)
                        SqlCmd.ExecuteNonQuery()
                    End Using

                    Dim dReader As OleDb.OleDbDataReader = cmd.ExecuteReader
                    Dim sqlBulk As SqlClient.SqlBulkCopy = New SqlClient.SqlBulkCopy(conn)
                    excelConnection.Close()

                End Using

            Catch ex As Exception
                ' Handle errors here

            Finally
                If Not excelConnection.State = ConnectionState.Closed Then
                    Try
                        excelConnection.Close()
                    Catch ex As Exception
                    End Try
                End If

            End Try

        End Using

首先，您将excel数据加载到datagridview中。 之后，所有来自gridview的数据都必须插入到表数据库中。 它会解决您的问题。 您必须尝试一下！

首付-

1个按钮-btnOpen-

1个文本框-txtOpen-

再次按下1个按钮-btnLoad-

1个datagridview-DataGridView3-

1个组合框-cboSheet

在OpenButton中。 输入此代码

 Dim OpenFileDialog1 As New OpenFileDialog()
    Dim constr As String
    Dim con As OleDb.OleDbConnection

    Try

        OpenFileDialog1.Filter = "Excel Files | *.xlsx; *.xls; *.xlsm;"

        If OpenFileDialog1.ShowDialog() = System.Windows.Forms.DialogResult.OK Then
            Me.txtOpen.Text = OpenFileDialog1.FileName

            constr = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + txtOpen.Text + ";Excel 12.0 Xml;HDR=YES"
            con = New OleDb.OleDbConnection(constr)
            con.Open()

            cboSheet.DataSource = con.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, Nothing)
            cboSheet.DisplayMember = "TABLE_NAME"
            cboSheet.ValueMember = "TABLE_NAME"
        End If
    Catch ex As Exception
        MessageBox.Show(ex.Message)
    End Try

在“加载”按钮中，将此代码放在下面

 Dim constr As String
    Dim dt As DataTable
    Dim con As OleDbConnection
    Dim sda As OleDbDataAdapter
    Dim row As DataRow

    Try
        constr = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + txtOpen.Text + ";Excel 12.0 Xml;HDR=YES"
        con = New OleDbConnection(constr)
        sda = New OleDbDataAdapter("Select * from [" + cboSheet.SelectedValue + "]", con)
        dt = New DataTable
        sda.Fill(dt)

        For Each row In dt.Rows
            DataGridView3.DataSource = dt

        Next
    Catch ex As Exception
        MessageBox.Show(ex.Message)
    End Try

然后将所有数据保存到表数据库中。 在下面使用此代码

'Dim nu As NullReferenceException
    Dim cmd As OleDbCommand
    connection.Open()
    For i As Integer = 0 To DataGridView3.Rows.Count - 2 Step +1

        'cmd = New OleDbCommand("INSERT INTO QAtable([CompanyCode],[Vendor],[G/L_Account],[DocumentType],[DocumentNumber],[DocumentDate],[EntryDate],[PostingDate],[NetDueDate],[ClearingDate],[ClearingDocument],[DocumentCurrency],[AmountInDocumentCurrency],[LocalCurrency],[AmountInLocalCurrency],[LocalCurrency2],[AmountInLocalCurrency2],[LocalCurrency3],[AmountInLocalCurrency3],[PartnerBankType],[PaymentBlock],[PaymentMethod],[Text],[DocumentHeaderText],[Assignment],[Username],[ABSvalueInAUD],[High/Low],[AmountRange]) VALUES (@CompanyCode,@Vendor,@G/L_Account,@DocumentType,@DocumentNumber,@DocumentDate,@EntryDate,@PostingDate,@NetDueDate,@ClearingDate,@ClearingDocument,@DocumentCurrency,@AmountInDocumentCurrency,@LocalCurrency,@AmountInLocalCurrency,@LocalCurrency2,@AmountInLocalCurrency2,@LocalCurrency3,@AmountInLocalCurrency3,@PartnerBankType,@PaymentBlock,@PaymentMethod,@Text,@DocumentHeaderText,@Assignment,@Username,@ABSvalueInAUD,@High/Low,@AmountRange)", connection)

        cmd.Parameters.Add("@AmountInLocalCurrency3", OleDbType.VarChar).Value = DataGridView3.Rows(i).Cells(19).Value.ToString()
        cmd.Parameters.Add("@PartnerBankType", OleDbType.VarChar).Value = DataGridView3.Rows(i).Cells(20).Value.ToString()

        cmd.ExecuteNonQuery()




    Next
    connection.Close()
    MessageBox.Show("All Data Inserted")

我希望它能起作用！ :)
