title: SQL Insert with where conditions for all fields
body: <p>I have a question about the SQL. There is a table with 3 fields. </p>
  
  <ul>
  <li>ID (auto number by access)</li>
  <li>First Name (Text)</li>
  <li>Last Name (Text)</li>
  </ul>
  
  <p>The following is the data</p>
  
  <p>Data </p>
  
  <pre><code>ID   FirstName     LastName
  ============================
  1    John          Chan
  2    May           Wong
  3    Tim           Leung
  </code></pre>
  
  <p>I want to insert the first name and last name to the table, but the first name and last name must not be the same from the existing data in table. For example, it is okay when I enter John Lee and Tim Wong, but not Tim Leung.</p>
  
  <p>Can I use 1 SQL to finish this part? Thank you very much.</p>
