c# - 存储过程删除查询不起作用。但是当它自己在编辑器中运行而不调用它时它可以正常工作

Question

我使用 SQL Server Management Studio 编写了这个存储过程。

如果我在编辑器中执行它并手动分配一个表单名称和一个用户 ID，它会正常工作清理不匹配的设置

ALTER PROCEDURE [dbo].[Handover_DeleteBadParams] 
     @UserID varchar(10), 
     @formName varchar (30)
as
begin
   with deletethese as
   (     
       select 
           UserID, Param 
       from
           BI.dbo.Handover_RDL_SavedSettings userSettings
       left join
           BI.dbo.Handover_UI form on Form.FormName = userSettings.FormName 
                                   and userSettings.Param = Form.ItemValue
       where 
          userSettings.FormName = @UserID
          and userSettings.UserID = @formName
          and Form.FormName IS NULL)
   Delete from S
   from bi.dbo.Handover_RDL_SavedSettings S
   join deletethese D on S.UserId = D.UserID and S.Param = D.Param;
end

然后我用C#调用存储过程

using (SqlCommand kill = new SqlCommand("Handover_DeleteBadParams",cc))
{
    kill.CommandType = CommandType.StoredProcedure;
    kill.Parameters.Add("@UserID", SqlDbType.VarChar).Value = userID;
    kill.Parameters.Add("@formName", SqlDbType.VarChar).Value = working_form_name;

    kill.Connection.Open();
    kill.ExecuteNonQuery();
    kill.Connection.Close();
}

我在执行过程中没有收到任何错误或任何类型的反馈......我在这里做错了什么？

我注意到的一个问题是在您的存储过程中您似乎颠倒了参数:

 where userSettings.FormName = @UserID
 and userSettings.UserID = @formName

应该是

 where userSettings.FormName =  @formName
 and userSettings.UserID = @UserID
