解析和使用C＃加載文本文件導入數據庫和存儲過程

我有「尋找過程或函數‘Cup_INSFuneralHome與解析和使用C＃加載文本文件導入數據庫和存儲過程

一個持續的錯誤問題’需要參數‘@funeralhomename’，但未提供「。

我做了許多改動，但沒有任何效果，所以我必須從我看錯了地方。

當我調試時，它好像按正確的順序提取正確的信息。

公司名稱
地址
市州郵編
電話

我敢卡在此：作爲原始文本文件被格式化。我瀏覽了其他帖子，但一直未能找到我需要的東西，或者能夠從大量'有點'類似的帖子中提取我需要的東西。恐怕問題就在我面前，但我看不到它。我需要一雙新的眼睛。所以我提前道歉。

PROC代碼：

cityid和stateid是uniqueidentifier ???你生氣嗎？？你期望有多少個州和城市？ – 2010-12-15 14:58:11

殯儀館基於「客戶」和/或墓地的城市和州 – 2010-12-15 16:24:47

非常感謝您，我已經實施了必要的更改，但是現在我得到'轉換失敗時，從字符串轉換爲唯一標識符'。我甚至改變了過程，並用UID去取得數據，但錯誤仍在繼續 – 2010-12-15 19:10:17

您沒有添加SQL參數的cmd對象;-)

看起來像你需要添加參數在執行之前查詢您的查詢。

你可以像這樣快捷這樣的：

cmd.Parameters.Add("@thing", SqlDbType.Type).Value = value;

你的情況：

cmd.Parameters.Add("@funeralhomename", SqlDbType.NVarChar).Value = funeralhomename; 
cmd.Parameters.Add("@addressone", SqlDbType.NVarChar).Value = street; 
cmd.Parameters.Add("@addresstwo", SqlDbType.NVarChar).Value = street2; 
cmd.Parameters.Add("@cityname", SqlDbType.NVarChar).Value = city; 
cmd.Parameters.Add("@State", SqlDbType.NVarChar).Value = state; 
cmd.Parameters.Add("@zipCode", SqlDbType.NChar).Value = zip; 
cmd.Parameters.Add("@Telephone", SqlDbType.NChar).Value = tel; 
cmd.Parameters.Add("@PrimaryContact", SqlDbType.NVarChar).Value = PrimaryContact; 
cmd.Parameters.Add("@EmailAddress", SqlDbType.NVarChar).Value = EmailAddress;

您創建的SqlParameter [] PARAM但集合不是什麼SqlCommand的使用時，它執行的程序。擺脫整個集合並改用命令的Parameter屬性。

cmd.Parameters.AddWithValue("@funeralhomename", funeralhomename)

，並做到這一點，在查詢所有參數

更合理，代碼更簡潔！但是，現在有一個轉換錯誤 – 2010-12-15 16:20:43

...從字符串轉換爲uniqueidentifier時轉換失敗。 – 2010-12-15 16:21:15

聽起來就像你試圖給uniqueidentifier參數添加一個字符串值。試試： cmd.Parameters.AddWithValue（「@ myparameter」，new Guid（myStringValue）） – Jeff 2011-01-07 17:57:15

你需要利用比如SqlCommand.Parameters.AddRange方法爲您的參數添加到您的SqlCommand對象：

SqlCommand cmd = new SqlCommand("Cup_INSFuneralHome", conn); 
       cmd.CommandType = CommandType.StoredProcedure; 

       SqlParameter[] param = new SqlParameter[9]; 
       param[0] = new SqlParameter("@funeralhomename", SqlDbType.NVarChar); 
       param[0].Value = funeralhomename; 
       param[1] = new SqlParameter("@addressone", SqlDbType.NVarChar); 
       param[1].Value = street; 
       param[2] = new SqlParameter("@addresstwo", SqlDbType.NVarChar); 
       param[2].Value = street2; 
       param[3] = new SqlParameter("@cityname", SqlDbType.NVarChar); 
       param[3].Value = city; 
       param[4] = new SqlParameter("@State", SqlDbType.NVarChar); 
       param[4].Value = state; 
       param[5] = new SqlParameter("@zipCode", SqlDbType.NChar); 
       param[5].Value = zip; 
       param[6] = new SqlParameter("@Telephone", SqlDbType.NChar); 
       param[6].Value = tel; 
       param[7] = new SqlParameter("@PrimaryContact", SqlDbType.NVarChar); 
       param[7].Value = PrimaryContact; 
       param[8] = new SqlParameter("@EmailAddress", SqlDbType.NVarChar); 
       param[8].Value = EmailAddress; 

cmd.Parameters.AddRange(param);
