joinコマンドを逆にする

Question

私はasp.net VBで書かれたプロジェクトとmssqlを使っているimを引き継いでいます。ユーザーがクリックを提出したときに

私は私がやりたいどのような施設（FacName）のテキスト値を持つテキストボックス

を持っているが、プログラムは見上げ、テキストボックスに入力されたテキストを取ります施設テーブルを検索し、施設名を見つけ、施設IDと一致させ、および、エピソード施設ID列を更新する。ここで

は私の二つの表のとおりです。

Episode     Facilities 

ID__________FacilityID | ID__________FacName 
1___________10   | 10__________Beenleigh 
2___________14   | 14__________Sunnybank 
3___________15   | 15__________Brisbane 

ユーザーが別の施設を指すようにエピソードを更新 - '、この場合には、新しいfacililityを参照するために、彼らはEpisode.ID「2」をしたいとしましょうブリスベン」

彼らテキストボックスに入力ブリスベンと提出ヒット、となるエピソード表の結果：

Episode     Facilities 

ID__________FacilityID | ID__________FacName 
1___________10   | 10__________Beenleigh 
2___________15   | 14__________Sunnybank 
3___________15   | 15__________Brisbane 

施設]タブで検索を行うので、その種le.FacilityID列

私はよく働くために私の選択した声明を得ました、うまくいけば誰かが私の質問に答えるのを助けるでしょう！ 動作していないUPDATE声明

わかりましたが、私がやってしまったものですselect文作業

ashxハンドラも使用したjqueryドロップダウンリストを使用していましたが、私はFacility名I私はちょうどID名を必要としたので、IDを投稿時にデータベースにポストすることができました。だから私はそうのような施設名をIDに引っ張るなどして、SQLコマンドをモッド：

Public Class Search_VB : Implements IHttpHandler 

Public Sub ProcessRequest(ByVal context As HttpContext) Implements IHttpHandler.ProcessRequest 
    Dim prefixText As String = context.Request.QueryString("q") 
    Dim conn As SqlConnection = New SqlConnection 
    conn.ConnectionString = ConfigurationManager _ 
      .ConnectionStrings("CDI").ConnectionString 
    Dim cmd As SqlCommand = New SqlCommand 
    cmd.CommandText = ("select ID, FacName from Facilities where FacName like '%' + @SearchText + '%'") 


    cmd.Parameters.AddWithValue("@SearchText", prefixText) 
    cmd.Connection = conn 
    Dim sb As StringBuilder = New StringBuilder 

    conn.Open() 
    Dim sdr As SqlDataReader = cmd.ExecuteReader 
    While sdr.Read 
     sb.Append(sdr("FacName") & (" ID: ")) 
     sb.Append(sdr("ID")).Append(Environment.NewLine) 


    End While 
    conn.Close() 
    context.Response.Write(sb.ToString) 

End Sub 

the drop down list showing facility id's だから今、私は私がポストバックの準備ができて施設IDをつかむために必要な、私の施設IDを持っていました。

だから私は、ページのスクリプトタグで次のように更新：

<script type="text/javascript"> 
    //the code below gets the jquery drop down working, and uses the ashx handler to feed it results to populate the list 
    $(document).ready(function() { 
     $('[id$=txt_Search]').autocomplete('/Facility_Search.ashx'); 


     //monitor for when the user clicks the update button. 
     $("[id$=Button1]").click(function() { 

      //fetch the selected value from the text box 
      FacNameTextValue = $('[id$=txt_Search]').val() 
      //pull off the prefix (the facility name, leaving only the characters after the : character, this should 
      //only leave the facility ID 
      FacNameTextValue = FacNameTextValue.substring(FacNameTextValue.indexOf(":") + 2); 
      //Filter everything out except numbers 
      FacNameTextValue = FacNameTextValue.replace(/\D/g, ''); 
      // Now if the string is empty, we need to alert the user that no Facility match was found, and they need to create a new one. 


      //Now populate the text box with the filtered facility ID 
      document.getElementsByName('DetailsViewEpisodeEdit$FacilityIDTextBox')[0].value = FacNameTextValue; 
      //alert is for debug purposes bellow, comment out when the code is working :) 
      //alert(":" + FacNameTextValue + ":"); 

      //now check the string, and if we are left with nothing, then alert the user that the record will be left blank 
      if (FacNameTextValue.length < 1) { 
       alert("No matching facilility was found, facility field will be left blank.") 
      } 







     }); 

    }); 
</script> 

だから、あなたはそれを持っています。お役に立てれば。これは実際にそれを行う横方向の方法だと確信しています。提案/改善があれば教えてください！
