Question

我正在尝试将我的textedit值存储到MS Access数据库，但我收到的错误是“查询值和目标字段的数量不相同”。但我的查询值和目标字段是相同的。我尝试在两种方法中插入同样的错误。

我先试过这个方法

        int invoicenumber = Convert.ToInt32(TXE_Invoice_Number.Text);
        string terms = CBL_Terms.Text;
        DateTime date = CBL_Date.DateTime;
        string ourquote = TXE_OurQuote.Text;
        string salesperson = CBL_Sales_Person.Text;
        string customername = CBL_Customer_Nmae.Text;
        string oderno = CBL_Order_Number.Text;
        string invoiceaddress = TXE_Invoice_Address.Text;
        string deliveryaddress = TXE_Delivery_Address.Text;

        decimal wholediscper = Convert.ToDecimal(TXE_FlatDiscountP.Text);
        decimal wholediscamt = Convert.ToDecimal(TXE_FlatDiscountA.Text);
        decimal shippingpercenatge = Convert.ToDecimal(TXE_ShippingPercentage.Text);
        decimal shippingamount = Convert.ToDecimal(TXE_ShippingAmount.Text);
        decimal unitprice = Convert.ToDecimal(TXE_SubTotal.Text);
        decimal discount = Convert.ToDecimal(TXE_Discount.Text);
        decimal tax = Convert.ToDecimal(TXE_Tax.Text);
        decimal shiping = Convert.ToDecimal(TXE_Shipping.Text);
        decimal grandtotal = Convert.ToDecimal(TXE_GrandTotal.Text);


        OleDbCommand top = new OleDbCommand(
            "INSERT INTO NewInvoice_1 (" +
            "InvoiceNumber,Terms,[InvoiceDate],OurQuote," +
            "SalesPerson,CustomerName,OrderNumber," +
            "InvoiceAddress,DeliveryAddress," +
            "WholeDiscountP,WholeDiscountA,ShippingP,ShippingA" +
            "Price,Discount,Tax" +
            "Shipping,GrandTotal" +
            ") VALUES (?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?)", conn);

        top.Parameters.AddWithValue("?", invoicenumber);
        top.Parameters.AddWithValue("?", terms);
        top.Parameters.AddWithValue("?", date);
        top.Parameters.AddWithValue("?", ourquote);
        top.Parameters.AddWithValue("?", salesperson);
        top.Parameters.AddWithValue("?", customername);
        top.Parameters.AddWithValue("?", oderno);
        top.Parameters.AddWithValue("?", invoiceaddress);
        top.Parameters.AddWithValue("?", deliveryaddress);

        top.Parameters.AddWithValue("?", wholediscper);
        top.Parameters.AddWithValue("?", wholediscamt);
        top.Parameters.AddWithValue("?", shippingpercenatge);
        top.Parameters.AddWithValue("?", shippingamount);
        top.Parameters.AddWithValue("?", unitprice);
        top.Parameters.AddWithValue("?", discount);
        top.Parameters.AddWithValue("?", tax);
        top.Parameters.AddWithValue("?", shiping);
        top.Parameters.AddWithValue("?", grandtotal);

        top.ExecuteNonQuery();

第二种方法

        int invoicenumber = Convert.ToInt32(TXE_Invoice_Number.Text);
        string terms = CBL_Terms.Text;
        DateTime date = CBL_Date.DateTime;
        string ourquote = TXE_OurQuote.Text;
        string salesperson = CBL_Sales_Person.Text;
        string customername = CBL_Customer_Nmae.Text;
        string oderno = CBL_Order_Number.Text;
        string invoiceaddress = TXE_Invoice_Address.Text;
        string deliveryaddress = TXE_Delivery_Address.Text;

        decimal wholediscper = Convert.ToDecimal(TXE_FlatDiscountP.Text);
        decimal wholediscamt = Convert.ToDecimal(TXE_FlatDiscountA.Text);
        decimal shippingpercenatge = Convert.ToDecimal(TXE_ShippingPercentage.Text);
        decimal shippingamount = Convert.ToDecimal(TXE_ShippingAmount.Text);
        decimal unitprice = Convert.ToDecimal(TXE_SubTotal.Text);
        decimal discount = Convert.ToDecimal(TXE_Discount.Text);
        decimal tax = Convert.ToDecimal(TXE_Tax.Text);
        decimal shiping = Convert.ToDecimal(TXE_Shipping.Text);
        decimal grandtotal = Convert.ToDecimal(TXE_GrandTotal.Text);

        OleDbCommand top = new OleDbCommand("INSERT INTO test_top(InvoiceNumber,Terms,[InvoiceDate],OurQuote,SalesPerson,CustomerName,OrderNumber,InvoiceAddress,DeliveryAddress,WholeDiscountP,WholeDiscountA,ShippingP,ShippingA,Price,Discount,Tax,Shipping,GrandTotal) VALUES (" + invoicenumber + ",'" + terms + "','" + date + "','" + ourquote + "','" + salesperson + "','" + customername + "','" + oderno + "','" + invoiceaddress + "','" + deliveryaddress + "',"+ wholediscper +","+ wholediscamt +","+ shippingpercenatge +","+ shippingamount +"," + unitprice + "," + tax + "," + grandtotal + ")", conn);

在两种方法中获得相同的错误？我的代码有什么问题？帮帮我

Answer 1

中的“ShippingA”后面缺少逗号

"WholeDiscountP,WholeDiscountA,ShippingP,ShippingA".

因此，当您的列名称正确时，列数会减一。

查询值和目标字段的数量在C＃中不是相同的错误？
