title: How to select only 1 row from oracle sql?
body: <p>I want to use oracle syntax to select only 1 row from table <code>DUAL</code>.  For example, I want to execute this query:</p>
  
  <pre><code>SELECT user 
    FROM DUAL
  </code></pre>
  
  <p>...and it'd have, like, 40 records.  But I need only one record.  ...AND, I want to make it happen without a <code>WHERE</code> clause.</p>
  
  <p>I need something in the table_name field such as:</p>
  
  <pre><code>SELECT FirstRow(user) 
    FROM DUAL
  </code></pre>
