title: When should we use `` or '' in mySQL?
body: <p>CREATE TABLE <code>counties</code> (
        <code>id</code> int(11) NOT NULL auto_increment,
        <code>county</code> tinytext NOT NULL,
        PRIMARY KEY  (<code>id</code>)
      ) TYPE=MyISAM;</p>
  
  <pre><code>-- 
  INSERT INTO `counties` VALUES (1, 'Alachua County');
  </code></pre>
  
  <p>I have seen some patterns here.
  People uses `` to surround field names and use '' to surround values.
  Is that true? </p>
  
  <p>Or the major reason to do so is because then we can put the code in a text file and import into the database.</p>
  
  <p>thank you</p>
