title: Insert manually into a table by SQL statement, but key is autoincremented
body: <p>Let's say I have a table of users and the <code>id</code> column is the primary key and auto incremented. </p>
  
  <p>I want to just try and add user manually by this statement:</p>
  
  <pre><code>INSERT INTO table_name (id, username, password)  
  VALUES (?, Mike, Mike);
  </code></pre>
  
  <p>but I don't want to specify the <code>?</code> value, just want to add to the next row.</p>
  
  <p>Thanks everyone, I forgot to set the id column to auto increment. it works now.</p>
