title: Show the structure of the table in SQL
body: <p>Can someone explain things a little better to me? How do I show the structure of a table? 
  I run the <code>select * from table</code>; and of course it displays all that's in the table. But, I am being asked to show the structure of the table. What does that mean, and what is the command?</p>
  
  <p>Here's my table below.</p>
  
  <pre><code>SQL&gt; select * from dept;
  
  DEPTNO DNAME          LOC
  ---------- -------------- -------------
      10 ACCOUNTING     NEW YORK
      20 RESEARCH       DALLAS
      30 SALES          CHICAGO
      40 OPERATIONS     BOSTON
  
   SQL&gt;
  </code></pre>
