SqlDataSource过程或函数需要未指定的参数
本文关键字：未指定 参数 过程 函数 SqlDataSource | 更新日期: 2023-09-27 18:20:58
我有一个SqlDataSource，我正试图向其添加UpdateCommand，以便在选择GridView的更新按钮时可以调用存储过程。由于需要调用两个过程中的一个，这取决于记录是否已经存在于数据库表中（INSERT表示新记录，UPDATE表示现有记录），因此我在代码隐藏中执行此操作。当我在RowUpdating事件中设置Updateparameters时，我得到以下异常：
过程或函数"usp_TestLogInsert"需要参数"@Status"，但未提供该参数
这里是ASP代码和代码背后的这一点。我在后面的代码中显式地创建参数，所以我不明白为什么会出现这个异常。我已经验证了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
//}
}

您需要在参数名称之前去掉@，SqlDataSource会为您添加它。参见此处
当您实例化数据源时，也可以尝试添加参数，然后在代码后面设置它们的值：
<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();
}
