Question

首先发布在这里，所以我感谢您提前耐心等待我。我正在为我的网络应用程序执行插入存储过程而旋转轮胎，我希望更多的眼睛可以帮助。

首先是我的存储过程。

CREATE PROCEDURE dbo.InsertCurrencyRecord
    @SubCategoryId INT, @PortfolioOwnerId INT,
    @OwnerId INT, @ContactId INT,
    @LocationId INT,
    @Model VARCHAR(50), @Version VARCHAR(15) = NULL, 
    @Vendor VARCHAR(50), @AvailableDate DATE, 
    @EndOfProduction DATE, @EndOfSupport DATE,  
    @NumOfDevices VARCHAR(50), @Costs MONEY, 
    @UpgradeDuration INT,
    @Description VARCHAR(250), @SupportingComments VARCHAR(250)
AS
INSERT INTO dbo.Currency (SubCategoryId, PortfolioOwnerId, OwnerId, ContactId, LocationId, Model, Version, Vendor, AvailableDate, EndOfProduction, EndOfSupport, NumOfDevices, Costs, UpgradeDuration, Description, SupportingComments, ModifiedDate)
VALUES (@SubCategoryId, @PortfolioOwnerId, @OwnerId, @ContactId, @LocationId, @Model, @Version, @Vendor, @AvailableDate, @EndOfProduction, @EndOfSupport, @NumOfDevices, @Costs, @UpgradeDuration, @Description, @SupportingComments, GETDATE());
GO

第二个是asp.dropdownlists，其中我的一些参数应该来自。 SubcategoryId似乎是提供的，因为它是第一个参数，第二个参数是PortfolioId不是，虽然两者之间似乎没有什么不同。

<td style="text-align: right">SubCategory:</td>
        <td>
            <%-- Confirm from database what max length is --%>
            <asp:DropDownList ID="DDSubCategory" runat="server" Height="20px" Width="175px" AutoPostBack="True">
            </asp:DropDownList>
            <asp:RequiredFieldValidator ID="SubCategoryValidator" runat="server" ControlToValidate="DDSubCategory" Display="Dynamic" ErrorMessage="SubCategory Required" ValidationGroup="AllValidators" ForeColor="Red">*</asp:RequiredFieldValidator>
        </td>
        <td style="text-align: right; width: 181px;">Portfolio Owner:</td>
        <td>
            <asp:DropDownList ID="DDPortfolioOwner" runat="server" Height="20px" Width="175px" AutoPostBack="True">
            </asp:DropDownList>
            <asp:RequiredFieldValidator ID="PortfolioOwnerValidator" runat="server" ControlToValidate="DDPortfolioOwner" Display="Dynamic" ErrorMessage="Portfolio Owner Required" ValidationGroup="AllValidators" ForeColor="Red">*</asp:RequiredFieldValidator>
        </td>

最后将是我的c＃代码，显示执行存储过程的提交按钮单击方法。

protected void SubmitBtn_Click(object sender, EventArgs e) {
        if (Page.IsValid) {
            string constr = ConfigurationManager.ConnectionStrings["CurrencyDb"].ConnectionString;
            SqlConnection con = new SqlConnection(constr);
            SqlCommand cmd = new SqlCommand("dbo.InsertCurrencyRecord", con);
            cmd.CommandType = CommandType.StoredProcedure;
            cmd.Parameters.AddWithValue("@SubCategoryId", DDSubCategory.SelectedIndex);
            cmd.Parameters.AddWithValue("@PorfolioOwnerId", DDPortfolioOwner.SelectedIndex);
            cmd.Parameters.AddWithValue("@OwnerId", DDTechOwner.SelectedIndex);
            cmd.Parameters.AddWithValue("@ContactId", DDTechContact.SelectedIndex);
            cmd.Parameters.AddWithValue("@LocationId", DDBranch.SelectedIndex);
            cmd.Parameters.AddWithValue("@Model", ModelBox.Text);
            cmd.Parameters.AddWithValue("@Version", VersionBox.Text);
            cmd.Parameters.AddWithValue("@Vendor", VendorBox.Text);
            cmd.Parameters.AddWithValue("@AvailableDate", ProductAvailableBox.Text);
            cmd.Parameters.AddWithValue("@EndOfProduction", EndProductionBox.Text);
            cmd.Parameters.AddWithValue("@EndOfSupport", EndOfSupportBox.Text);
            cmd.Parameters.AddWithValue("@NumOfDevices", NumDevicesBox.Text);
            cmd.Parameters.AddWithValue("@Costs", UpgradeCostBox.Text);
            cmd.Parameters.AddWithValue("@UpgradeDuration", UpgradeDurationBox.Text);
            cmd.Parameters.AddWithValue("@Description", DescriptionBox.Text);
            cmd.Parameters.AddWithValue("@SupportingComments", NotesBox.Text);

            try {
                con.Open();
                cmd.ExecuteNonQuery();
                labelMessage.Text = "Your request has been submitted for review.";
            }
            catch (Exception ex) {
                throw new Exception("Error adding record. " + ex.Message);
            }
            finally {
                if (con != null)
                    con.Close();
            }
        }

Answer 1

这里

cmd.Parameters.AddWithValue("@PorfolioOwnerId", DDPortfolioOwner.SelectedIndex)

你错过了 t 中的t folioOwnerId

因此，'InsertCurrencyRecord'过程不会收到预期的参数'@PortfolioOwnerId'

添加记录时出错。过程或函数'InsertCurrencyRecord'需要参数'@PortfolioOwnerId'
