我有以 xml 作为输入的存储过程。

执行 SP 的 C# 代码是

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 方法返回一个 xml 数据形式的字符串。在我存储的过程中，我删除了 SET NOCOUNT ON 以返回插入、删除或更新时的实际行数。如果我使用示例 xml 数据运行查询:-

<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，因为在我的集合中我只传递了一个需要插入的行。因为没有更新或删除的行。当 SP 必须返回 1 时，它如何返回 3？

存储的过程是

  set ANSI_NULLS ON
  set QUOTED_IDENTIFIER ON
   go



  ALTER PROCEDURE [dbo].[sp_Configure_Users]
@XMLDATA xml
  AS
 DECLARE @Users_Staging Table(
[User_Id] [int] NOT NULL,

如果您的存储过程更新/插入的表上有触发器，它们将影响受影响的行数：

对于 UPDATE、INSERT 和 DELETE 语句，返回值是受命令影响的行数。当正在插入或更新的表上存在触发器时，返回值包括受插入或更新操作影响的行数以及受一个或多个触发器影响的行数。对于所有其他类型的语句，返回值为 -1。如果发生回滚，则返回值也是 -1。
参考。

建议您发布所涉及表的存储过程和架构/触发器。
