將行插入多個表失敗

-1

我有一個存儲過程，即將行同時插入多個表。存儲過程中存在的問題是它沒有被解僱。你可以看看這個語法是否正確並正常工作。將行插入多個表失敗

怎麼過這個存儲過程工作正常，而我從管理工作室從代碼執行的背後它的成功執行，但不插入記錄表。那裏爲我包括這個databasehelper.cs代碼：

/// <summary> 
    /// Adds answer in the [tbl_Inquiry_master] table. 
    /// </summary> 
    public static void AddPostReply(string inquiry_id,string user_id,string priority_type, string status_name, string inquiry_content,int question_id,out string reply_id,out string user_name,out string user_email) 
    { 
     using (SqlConnection con = Util.GetConnection()) 
     { 
      con.Open(); 
      AddPostReply(con,inquiry_id,user_id,priority_type, status_name, inquiry_content, question_id,out reply_id,out user_name,out user_email); 
     } 
    } 
    /// <summary> 
    /// Adds answer in the [tbl_Inquiry_master] table. 
    /// </summary> 
    public static void AddPostReply(SqlConnection con, string inquiry_id, string user_id, string priority_type, string status_name, string inquiry_content, int question_id, out string reply_id, out string user_name, out string user_email) 
    { 
     AddPostReply(con, null, inquiry_id, user_id, priority_type, status_name, inquiry_content, question_id, out reply_id, out user_name, out user_email); 
    } 
    /// <summary> 
    /// Adds answer in the [tbl_Inquiry_master] table. 
    /// </summary> 
    public static void AddPostReply(SqlConnection con, SqlTransaction trans, string inquiry_id, string user_id, string priority_type, string status_name, string inquiry_content, int question_id, out string reply_id, out string user_name, out string user_email) 
    { 
     using (SqlCommand cmd = new SqlCommand("[dbo].[InquiryPostReply]", con)) 
     { 
      cmd.CommandType = CommandType.StoredProcedure; 
      cmd.Parameters.Add("@Inquiry_id", SqlDbType.VarChar).Value = inquiry_id; 
      cmd.Parameters.Add("@User_id", SqlDbType.VarChar).Value = user_id; 
      cmd.Parameters.Add("@Priority_type", SqlDbType.VarChar).Value = priority_type; 
      cmd.Parameters.Add("@Status_name", SqlDbType.VarChar).Value = status_name; 
      cmd.Parameters.Add("@Inquiry_Content", SqlDbType.VarChar).Value = inquiry_content;

      cmd.Parameters.Add("@user_email", SqlDbType.VarChar, 50).Direction = ParameterDirection.Output; 
      cmd.Parameters.Add("@NewId", SqlDbType.VarChar, 50).Direction = ParameterDirection.Output; 
      if (trans != null) 
      trans = con.BeginTransaction(); 
     cmd.ExecuteNonQuery(); 
     trans.Commit(); 
      user_name = Convert.ToString(cmd.Parameters["@user_name"].Value); 
      user_email = Convert.ToString(cmd.Parameters["@user_email"].Value); 
      reply_id = Convert.ToString(cmd.Parameters["@NewId"].Value); 
     } 
    }

該錯誤發生這樣的：

對於第三個時間刪除交易和測試。該錯誤在trans.Commit（）行上。首先確定問題是否存在於SP中。 – Paparazzi

SP工作正常... –

然後最有可能的反式反應是空的。您還應該在行Commit行上測試null。 – Paparazzi

您需要在連接上打開事務，執行你的語句，然後提交這些更改。

trans = con.BeginTransaction(); 
cmd.ExecuteNonQuery(); 
trans.Commit();

這段代碼並不能幫助我將這段代碼實現到我的方法中。 –

根據我的迴應，你已經實現的代碼應該可以工作。你收到的錯誤是從SQL Server冒泡，意味着你的數據正在提交，但你有衝突。你需要修改你的SQL過程。 – dgarbacz

和我如何修改它.. –

這看起來像一個問題，我

IF @var1 = '1' AND @var1 = '2'

這將始終返回false

而你需要提交事務的起訴由dgarbacz

我更新了我的存儲過程，但是這給我錯誤請參閱更新部分。 –

您仍然沒有提交交易。首先嚐試刪除交易。 – Paparazzi

雅我更新我的問題只是看看，並給你的建議。 –
