title: Common_schema function get_option not found after installation
body: <p>So I've installed common_schema to my mysql server and tried to do action with get_option function.</p>
  
  <p>My SQL:</p>
  
  <pre><code>SELECT *, ((get_option("program_invested_details", "received") * 100) / get_option("program_invested_details", "invested")) AS PERCENT_TOTAL FROM hp_programs_list WHERE program_add_status = 4 AND program_status = 1 ORDER BY PERCENT_TOTAL DESC
  </code></pre>
  
  <p>but it seems, that get_option function doesn't work, becouse I got this error:</p>
  
  <blockquote>
    <p>FUNCTION hyips_database.get_option does not exist</p>
  </blockquote>
  
  <p>my DB structure:</p>
