title: Equivalent function for DATEADD() in Oracle
body: <p>I have to get a date that is 6 months from the system date in Oracle.<br> And I have to get it by running an open-query from SQL. <code>DATEADD(MONTH,-6, GETDATE())</code>  function serves the purpose in SQL.<br><br>
  Does the function <code>DATEADD(MONTH,-6, GETDATE())</code> in SQL have an <code>equivalent</code> function in Oracle?</p>
