title: datatable select rows
body: <p>I am using a datatable created by program. In this datatable i want to insert values in some specified columns.</p>
  
  <p>Initially I am inserting primary key values leaving remaining columns null, when I am querying datatable with recently inserted value in Primary column to update same row, I am facing error  <code>Missing operand after ID operator</code></p>
  
  <p>Can any one tell me the exact issue.</p>
  
  <p>I am trying following code:</p>
  
  <pre><code> dt.Rows.Add(1);
   int insertedValue = 1;
   DataRow[] dr = dt.Select("ID = '" + insertedValue.toString() + "'");
  </code></pre>
  
  <p>And the table structure after entring primary value is as follows.</p>
  
  <pre><code>ID    Volumn1    Volumn2    volumn3
  --------------------------------------
  1
  </code></pre>
