title: DELETE unknown column 'int value' in 'where clause'
body: <p>I have a table that has got one A_I column named link_id. When I run like that:</p>
  
  <pre><code>$link_id = 32;
  $query1 = "DELETE FROM links WHERE link_id = $link_id";
  if(!mysql_query($query1,$connection));
  {
      die(mysql_error($connection));
  }
  </code></pre>
  
  <p>It works succesfully but when I try this with C# WebRequest:</p>
  
  <pre><code>WebRequest request = WebRequest.Create("http://www.mywebsite.com/deleteLink.php");
  request.Method = "POST";
  string post = "link_id=" + id //type string;
  byte[] postBytes = Encoding.UTF8.GetBytes(post);
  request.ContentLength = postBytes.Length;
  request.ContentType = "application/x-www-form-urlencoded";
  Stream dataStream = await request.GetRequestStreamAsync();
  dataStream.Write(postBytes, 0, postBytes.Length);
  WebResponse response = await request.GetResponseAsync();
  return new StreamReader(response.GetResponseStream()).ReadToEnd();
  </code></pre>
  
  <p>returns : Unknown column '32' in 'where clause'</p>
  
  <p>Where am I doing wrong? Thanks.</p>
