Question

我的情况是这样的。我有一个需要更新的电话表（如果他们需要更改客户端的现有电话表）或删除（如果他们希望删除现有的号码）或插入（如果字段为空，则插入新的否）。我已经有两个存储过程，它们添加一个新电话并更新现有电话。其参数为：

 EXECUTE @RC = [CUSTOMER_test].[dbo].[uspAddClientTel] 
   @ClientID
  ,@TelNo
  ,@TelTypeID
  ,@DetailsTypeID
  ,@SortNo
  ,@ResultTelID OUTPUT 

EXECUTE @RC = [CUSTOMER_test].[dbo].[uspUpdateClientTel] 
   @TelID
  ,@TelNo
  ,@TelTypeID
  ,@DetailsTypeID
  ,@SortNo
  ,@ResultTelID OUTPUT
GO

表单视图中的部分查询

  (SELECT TOP 1 F.tel_no FROM TELEPHONE as F where F.tel_type_id = 3 AND F.client_id = @id ORDER BY sort_no ) AS fax, 
(SELECT TOP 1 T.tel_no from TELEPHONE as T where T.tel_type_id = 1 OR T.tel_type_id = 2 AND T.client_id = @id ORDER BY sort_no) AS telephone, 
(SELECT TOP 1 F.tel_id FROM TELEPHONE as F where F.tel_type_id = 3 AND F.client_id = @id ORDER BY sort_no ) AS faxid , 
(SELECT TOP 1 T.tel_id from TELEPHONE as T where T.tel_type_id = 1 OR T.tel_type_id = 2 AND T.client_id = @id ORDER BY sort_no) AS telephoneid ,
CLIENT_ADDRESS.client_address_id

  FROM ORGANIZATION AS O INNER JOIN CLIENT ON O.client_id = CLIENT.client_id
    LEFT OUTER JOIN CLIENT_ADDRESS ON  CLIENT.client_id = CLIENT_ADDRESS.client_id
 WHERE (CLIENT.client_id = @id)"

所以我有电话（如固定电话/移动电话）和传真及其ID，如果它们已存在于数据库中。

现在我需要创建一个接受参数的函数，从而根据传递给它的参数决定使用哪个sp。我完全迷失在这里。任何有关如何使用此功能的帮助将不胜感激。甚至链接到教程将有所帮助！再次感谢！

P.S 在尝试这个功能之前，我做了类似的事情，但它并不一致

protected void FrmClient_ItemUpdating(object sender, FormViewUpdateEventArgs e)
{
    string TelTypeID;
    string ResultTelID1 = "";

    int intClientID = (int)e.Keys[0];
    string strTelID = (string)e.OldValues["telephoneid"];
    string strFaxID = (string)e.OldValues["faxid"];


     SqlConnection conTel = new SqlConnection();
    conTel.ConnectionString = Convert.ToString(ConfigurationManager.ConnectionStrings["CUSTOMERConnectionString"]);
    conTel.Open();

    if (strTelID != "")
    {
        string strtelcmd = ("SELECT tel_type_id, details_type_id, sort_no from TELEPHONE where tel_id =" + strTelID);
        SqlCommand telcmd = new SqlCommand(strtelcmd, conTel);
        SqlDataReader rdrTel = telcmd.ExecuteReader();
        while (rdrTel.Read())
        {

            sdsClient.UpdateParameters["TelTypeID"].DefaultValue = rdrTel["tel_type_id"].ToString();
            sdsClient.UpdateParameters["DetailsTypeID"].DefaultValue = rdrTel["details_type_id"].ToString();
            sdsClient.UpdateParameters["SortNo"].DefaultValue = rdrTel["sort_no"].ToString();

        }
        rdrTel.Close();

    }


    else   if (strFaxID != "")
    {
        string strfaxcmd = ("SELECT tel_type_id, details_type_id, sort_no from TELEPHONE where tel_id ="+ strFaxID);
        SqlCommand faxcmd = new SqlCommand(strfaxcmd, conTel);
        SqlDataReader rdrfax = faxcmd.ExecuteReader();
        while (rdrfax.Read())
        {
            sdsClient.UpdateParameters["TelTypeID1"].DefaultValue = rdrfax["tel_type_id"].ToString();
            sdsClient.UpdateParameters["DetailsTypeID1"].DefaultValue = rdrfax["details_type_id"].ToString();
            sdsClient.UpdateParameters["SortNo1"].DefaultValue = rdrfax["sort_no"].ToString();
        }

        rdrfax.Close();

    }
    else if (strTelID == "")
    {

        SqlCommand cmdaddTel = new SqlCommand("uspAddClientTel",conTel);
        cmdaddTel.CommandType = CommandType.StoredProcedure;

        string strNewTel = (string)e.NewValues["telephone"]; 


        if (strNewTel.Trim().StartsWith("06") || strNewTel.Trim().StartsWith("07") )

            TelTypeID = "2";
        else
            TelTypeID = "1";


        cmdaddTel.Parameters.Add(new SqlParameter("@ClientID", intClientID));
        cmdaddTel.Parameters.Add(new SqlParameter("@TelNo",strNewTel ));
        cmdaddTel.Parameters.Add(new SqlParameter("@TelTypeID", TelTypeID));
        cmdaddTel.Parameters.Add(new SqlParameter("@DetailsTypeID", 1));
        cmdaddTel.Parameters.Add(new SqlParameter("@SortNo1", 1 ));
        cmdaddTel.Parameters.Add(new SqlParameter("@ResultTelID1", ResultTelID1));

        SqlDataReader rdrAddFax = cmdaddTel.ExecuteReader();

    }

    else if (strFaxID == "")
    {

        SqlCommand cmdaddFax = new SqlCommand("uspAddClientTel", conTel);
        cmdaddFax.CommandType = CommandType.StoredProcedure;

        string strNewFax = (string)e.NewValues["fax"];



        cmdaddFax.Parameters.Add(new SqlParameter("@ClientID", intClientID));
        cmdaddFax.Parameters.Add(new SqlParameter("@TelNo", strNewFax));
        cmdaddFax.Parameters.Add(new SqlParameter("@TelTypeID", 3));
        cmdaddFax.Parameters.Add(new SqlParameter("@DetailsTypeID", 2));
        cmdaddFax.Parameters.Add(new SqlParameter("@SortNo1", 1));
        cmdaddFax.Parameters.Add(new SqlParameter("@ResultTelID1", ResultTelID1));

        SqlDataReader rdrAddFax = cmdaddFax.ExecuteReader();
    }


    conTel.Close();


}

和formview的updatecommand中的sps。

Answer 1

你能不把这个逻辑纳入SP吗？那么根据传递给SP的参数，您可以插入或更新必要的记录吗？

我知道您建议您希望在业务逻辑中完成此操作，但由于您似乎没有使用ORM作为数据访问层，因此您可以快速保持ID（因为您只需要这样做）单程往返db）并在SP中整理？

嗨，我最后还是把它解决了。认为这可能对像我这样的初学者有帮助

  public void functUAD(int intClientID, string TelType, int TelID, string OldTelNumber, string NewTelNumber)
    {
        int ResultTelID = 0 ;
        int TelTypeID ;
        int Result= 0 ;


        SqlConnection conTel = new SqlConnection();
        conTel.ConnectionString = Convert.ToString(ConfigurationManager.ConnectionStrings["CUSTOMERConnectionString"]);
        conTel.Open();

        if (TelType.ToLower() == "fax")

            TelTypeID = 3;

        else if (NewTelNumber.Trim().StartsWith("06") || NewTelNumber.Trim().StartsWith("07"))

            TelTypeID = 2;
        else
            TelTypeID = 1;



       if (OldTelNumber != "" && NewTelNumber != "" )    //update old number with new number
        {


            SqlCommand cmdUpdateTel = new SqlCommand("uspUpdateClientTel", conTel);
            cmdUpdateTel.CommandType = CommandType.StoredProcedure;

            SqlCommand cmdSortNo = new SqlCommand("SELECT sort_no FROM TELEPHONE WHERE tel_id= " + TelID, conTel);
            string SortNo = (string)cmdSortNo.ExecuteScalar();


            cmdUpdateTel.Parameters.Add(new SqlParameter("@TelID", TelID));
            cmdUpdateTel.Parameters.Add(new SqlParameter("@TelNo", NewTelNumber));
            cmdUpdateTel.Parameters.Add(new SqlParameter("@TelTypeID", TelTypeID));
            cmdUpdateTel.Parameters.Add(new SqlParameter("@DetailsTypeID", 1));
            cmdUpdateTel.Parameters.Add(new SqlParameter("@SortNo", SortNo));
            cmdUpdateTel.Parameters.Add(new SqlParameter("@ResultTelID", ResultTelID));

            cmdUpdateTel.ExecuteNonQuery();

        }

        if (OldTelNumber == "" && NewTelNumber != "")   // add a newnumber
        {

            int SortNo = 0 ;
            SqlCommand cmdaddTel = new SqlCommand("uspAddClientTel", conTel);
            cmdaddTel.CommandType = CommandType.StoredProcedure;


            if (TelTypeID == 1)
                SortNo = 1;
            else
            {
                SqlCommand cmdSortNo = new SqlCommand("SELECT MAX(sort_no) from TELEPHONE where tel_id =" + TelID, conTel);
                int MaxSort = (int)cmdSortNo.ExecuteScalar();
                SortNo += MaxSort;
            }
            cmdaddTel.Parameters.Add(new SqlParameter("@ClientID", intClientID));
            cmdaddTel.Parameters.Add(new SqlParameter("@TelNo", NewTelNumber));
            cmdaddTel.Parameters.Add(new SqlParameter("@TelTypeID", TelTypeID));
            cmdaddTel.Parameters.Add(new SqlParameter("@DetailsTypeID", 1));
            cmdaddTel.Parameters.Add(new SqlParameter("@SortNo", SortNo ));
            cmdaddTel.Parameters.Add(new SqlParameter("@ResultTelID", ResultTelID));

            cmdaddTel.ExecuteNonQuery();

        }

        if (OldTelNumber != "" && NewTelNumber == "") // delete the old number
        {

            SqlCommand cmdDelete = new SqlCommand("RemoveClientTel", conTel);
            cmdDelete.Parameters.Add(new SqlParameter("@TelID",TelID));
            cmdDelete.Parameters.Add(new SqlParameter("@Result", Result));
            cmdDelete.ExecuteNonQuery();
        }
}

然后你可以使用适当的参数调用该函数！再见！
