數據沒有在c＃中插入，但在SQL Server查詢瀏覽器中插入相同的數據

Question

我有一個鏈接按鈕在我的GridView中，我有一些插入表中的值，但它沒有插入，但在調試模式下查詢數據時，當我測試SQL Server上它插入有啥問題

protected void gvPO_RowCommand(object sender, GridViewCommandEventArgs e) 
{ 
     if (e.CommandName == "Select") 
     { 
      c.GetConection(); 
      SqlCommand cmd = new SqlCommand("delete from tmpMateIN", c.con); 
      cmd.ExecuteNonQuery(); 
      DataTable dt; 

      int index = Convert.ToInt32(e.CommandArgument); 
      gvPO.SelectedIndex = index; 

      if (Convert.ToInt16(gvPO.SelectedIndex) < 0) 
      { 
       lblMsg.Text = "Please Select Code !"; 
       return; 
      } 

      dt = oAccount.GetPO((int)Session["CompCode"], 79, Convert.ToInt16(((LinkButton)gvPO.Rows[gvPO.SelectedIndex].Cells[0].FindControl("lnkCode")).Text.ToString())); 

      for (int i = 0; i < dt.Rows.Count; i++) 
      { 
       String s6 = "insert into tmpMateIN(compcode ,msttype ,mstcode,mstdate ,mstchno ,mstblno ,mstbldt ,mstcust ,itdsrno , itditem ,itdquan ,itdrema ,itemname ,acctname ,ItmSize , unitname ,itemsize ,chno , chdt ,godown, packsize ,itdRate , itdDisc , itdAmou , mstInvNo , mstOrdNo,mstInvDt ,mstOrdDt ,mstrema , mstexcDes , msttaxDes ,msttaxper , mstfrghtDes , mstfrghtper , mstdeliDes ,mstpayDes , mstvaliDes, mstqno, mstqdt , itdthickness , itdlength ,itdwidth ,itdweight, itdtowt , acctaddr , custemail , mstpayMode , mstdepa,itdrefq,itdorgq)values(" + (int)Session["CompCode"] + ",79,'" + dt.Rows[i]["mstcode"] + "','" + dt.Rows[i]["mstdate"] + "'," + dt.Rows[i]["mstchno"] + ",'" + dt.Rows[i]["mstchno"] + "','" + dt.Rows[i]["mstdate"] + "','" + dt.Rows[i]["mstptcode"] + "','" + (i + 1) + "','" + dt.Rows[i]["itditem"] + "','" + dt.Rows[i]["itdquan"] + "','" + dt.Rows[i]["itdrema"] + "','" + dt.Rows[i]["itdnarr"] + "','" + dt.Rows[i]["AcctName"] + "','" + dt.Rows[i]["itdnarr"] + "','" + dt.Rows[i]["UnitName"] + "' ,'" + dt.Rows[i]["itdunit"] + "','','" + dt.Rows[i]["mstdate"] + "','',''," + dt.Rows[i]["itdRate"] + "," + dt.Rows[i]["itdamou"] + " ," + dt.Rows[i]["itdAmou"] + ",'" + dt.Rows[i]["mstInvNo"] + "','" + dt.Rows[i]["mstindno"] + "','" + dt.Rows[i]["mstdate"] + "','" + dt.Rows[i]["mstdate"] + "','" + dt.Rows[i]["mstrema"] + "','','','" + dt.Rows[i]["mstTaxPer"] + "','" + dt.Rows[i]["mstfrghtDes"] + "','" + dt.Rows[i]["mstfrghtper"] + "','" + dt.Rows[i]["mstdeliDes"] + "','" + dt.Rows[i]["mstpayDes"] + "','" + dt.Rows[i]["mstvaliDes"] + "','" + dt.Rows[i]["mstqno"] + "','" + dt.Rows[i]["mstpodate"] + "','" + dt.Rows[i]["itdthickness"] + "','" + dt.Rows[i]["itdsource"] + "','" + dt.Rows[i]["itddestin"] + "','" + dt.Rows[i]["itdweight"] + "','" + dt.Rows[i]["itdtowt"] + "','','" + dt.Rows[i]["acctaddr"] + "','" + dt.Rows[i]["mstpayMode"] + "','" + dt.Rows[i]["mstContactPerson"] + "','" + dt.Rows[i]["mstlotno"] + "','" + dt.Rows[i]["mstsection"] + "')"; 

       SqlCommand cmd1 = new SqlCommand(s6, c.con); 
       cmd1.ExecuteNonQuery(); 
      } 

      c.CloseConnection(); 
      Response.Redirect("Poreport.aspx"); 
    } 
}

可以運行SQL Server Profiler，看是否呼叫在你的程序的執行時間，以SQL服務器所進行插入。

建議：你爲什麼不使用存儲過程而不是這個聯查詢這樣的：

var dr = dt.Rows[i]; 
SqlCommand cmd1 = new SqlCommand(s6, c.con); 
cmd1.CommandType = System.Data.CommandType.StoredProcedure; 
cmd1.CommandText = "tmpMateIN_Insert"; 
cmd1.Parameters.Add(new SqlParameter("@compcode", (int)Session["CompCode"]); 
cmd1.Parameters.Add(new SqlParameter("@msttype", 79); 
cmd1.Parameters.Add(new SqlParameter("@mstcode", dr["mstcode"]); 
cmd1.Parameters.Add(new SqlParameter("@mstdate", dr["mstdate"]); 
// ... 
cmd1.ExecuteNonQuery(); 

新增：
或者，如果你真的想堅持一個內聯查詢那麼優選的方法是使用參數化內聯查詢，如下所示：

String s6 = "insert into tmpMateIN(compcode, msttype, mstcode, mstdate, ..." + 
    "values(@compcode, @msttype, @mstcode, @mstdate, ..."; 

cmd1.Parameters.Add(new SqlParameter("@compcode", (int)Session["CompCode"]); 
cmd1.Parameters.Add(new SqlParameter("@msttype", 79); 
cmd1.Parameters.Add(new SqlParameter("@mstcode", dr["mstcode"]); 
cmd1.Parameters.Add(new SqlParameter("@mstdate", dr["mstdate"]); 
// ... 
cmd1.ExecuteNonQuery();
