c# - SqlDataSource 过程或函数需要未指定的参数

Question

我有一个 SqlDataSource，我正在尝试向其中添加 UpdateCommand，以便在选择 GridView 的更新按钮时可以调用存储过程。我在代码后面执行此操作是因为我需要调用两个过程之一，具体取决于数据库表中是否已存在记录(对于新记录，插入，对于现有记录，更新)。当我在 RowUpdating 事件中设置 Updateparameters 时，出现以下异常:

Procedure or function 'usp_TestLogInsert' expects parameter '@Status', which was not supplied.

这里是 ASP 代码和背后的代码。我在后面的代码中显式创建参数，所以我不明白为什么会出现此异常。我已经验证这些参数与存储过程所需的参数相同。

C#

protected void gvChecklist_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
    SQLConnections sql = new SQLConnections();
    SqlDataSource dsChecklist = (SqlDataSource)LoginView1.FindControl("dsChecklist");
    var dd = (DropDownList)gvChecklist.Rows[e.RowIndex].FindControl("ddStatus");
    var status = dd.SelectedValue;
    var testID = sql.SQLSelectSingle(String.Format("SELECT ID FROM Automation.manual.Tests WHERE Task = '{0}'", (String)e.OldValues["Task"]), "pwautosql01");
    string user = Page.User.Identity.Name;
    string notes = (String)e.NewValues["Notes"];
    string jira = (String)e.NewValues["JiraTicket"];
    var dbID = e.NewValues["ID"];
    string build = "TODO";

    if (dbID == null) //Record does not exist in TestLog, INSERT a new one
    {
        dsChecklist.UpdateCommand = "[Automation].[manual].[usp_TestLogInsert]";
        dsChecklist.UpdateCommandType = SqlDataSourceCommandType.StoredProcedure;
        dsChecklist.UpdateParameters.Add("@Status", TypeCode.Int32, status);
        dsChecklist.UpdateParameters.Add("@TestID", TypeCode.Int32, testID);
        dsChecklist.UpdateParameters.Add("@TestedBy", TypeCode.String, user);
        dsChecklist.UpdateParameters.Add("@Notes", TypeCode.String, notes);
        dsChecklist.UpdateParameters.Add("@JiraTicket", TypeCode.String, jira);
        dsChecklist.UpdateParameters.Add("@Build", TypeCode.String, build);

        dsChecklist.Update();
    }
    //else //Record already exists in TestLog. UPDATE
    //{
        //TODO
    //}
}

您需要省略参数名称之前的@，SqlDataSource 会为您添加它。请参阅here

还可以尝试在实例化数据源时添加参数，然后在后面的代码中设置它们的值:

<UpdateParameters>
    <asp:Parameter Name="Status"   Type="Int32" />
    <asp:Parameter Name="TestID"  Type="Int32" />
    <asp:Parameter Name="TestedBy"    Type="String" />
    <asp:Parameter Name="Notes"       Type="String" />
    <asp:Parameter Name="JiraTicket"     Type="String" />
    <asp:Parameter Name="Build" Type="String" />
</UpdateParameters>

然后:

if (dbID == null) //Record does not exist in TestLog, INSERT a new one
{
    dsChecklist.UpdateCommand = "[Automation].[manual].[usp_TestLogInsert]";
    dsChecklist.UpdateCommandType = SqlDataSourceCommandType.StoredProcedure;
    dsChecklist.UpdateParameters["@Status"].Value = status;
    dsChecklist.UpdateParameters["@TestID"].Value = testID;
    dsChecklist.UpdateParameters["@TestedBy"].Value = user;
    dsChecklist.UpdateParameters["@Notes"].Value = notes;
    dsChecklist.UpdateParameters["@JiraTicket"].Value = jira;
    dsChecklist.UpdateParameters["@Build"].Value = build;

    dsChecklist.Update();
}
