ExecuteNonQuery返回的是随机数而不是返回实际行

Question

我有存储过程，它将xml作为输入。

的C＃代码执行SP是

using (SqlConnection conn = new SqlConnection(connString)) 
{ 
    try 
    { 
     conn.Open(); 
     SqlCommand command = new SqlCommand("sp_Configure_Users", conn); 
     command.CommandType = CommandType.StoredProcedure; 
     var xmlData = new SqlParameter(parameterName: "@XMLDATA", value: GenerateXML(_userDetails)); 
     command.Parameters.Add(xmlData); 

     count = command.ExecuteNonQuery(); 
     if (count > 0) 
     { 
      return count; 
     } 
     else 
     { 
      return 0; 
     } 
    } 
    catch (SqlException ) 
    { 

    } 
} 

GenerateXML返回一个字符串，它是。在我的存储过程中我已删除SET NOCOUNT基于XML数据的形式返回我实际没有的方法当插入，删除或更新。如果我运行与样本XML数据查询列： -

<UserCollection> 
    <InsertList><Users User_Id="438" First_Name="Praveen" Middle_Name="" Last_Name="Kumar" Designation_Id="1" Email="" Contact_Number="96533" Updated_By="pkumar" /> 
    </InsertList> 
    <UpdateList></UpdateList> 
    <DeleteList></DeleteList> 
</UserCollection> 

返回的值是3而不是1如在我的收藏IM只传递单排，其需要是插入。因为没有更新或删除的行SP只能返回1时能返回3吗？

存储的过程是

    set QUOTED_IDENTIFIER ON

如果你有更新的表触发器/你的存储过程插入，它们会影响受影响的行数：

对于UPDATE，INSERT和DELETE语句，返回值是该命令影响的行数的 。当插入或更新的 表中存在触发器时，返回值包括受插入或更新操作影响的行的编号 以及受触发器或触发器影响的行的编号 。对于所有其他类型的 语句，返回值为-1。如果发生回滚，则返回值 的值也是-1。

建议您发布相关表的存储过程和模式/触发器。
