title: Explanation of % in SQL
body: <p>Could someone explain the difference between <code>%</code> in SQL? </p>
  
  <p>I understand that <code>%</code> is a wildcard that allows you to query results with <code>LIKE</code> results, i.e. <code>a%</code> for words starting with <strong>a</strong>, but I am confused why the wildcard can be used as <code>% 2 = 0</code> to query for even numbers? </p>
  
  <p>I saw an explanation that said <code>%</code> can be used as divide but I thought <code>/</code> was divide.</p>
