title: How do I print a triangle of stars using SQL
body: <p>Is it practically possible to create a triangle of stars like this as below in SQL.I know that this could be done easily in any other programming language like C,C++,Java but want to know whether it is really possible with just SQL or PL/SQL.I tried working on it with dual table in Oracle but couldn't get through it.</p>

   * *             * *

  </code></pre>
