Hi Can anyone tell me if the Analytical functions as shown in the extracted piece of SQL using the OVER clause are part of standard 9i SQL or is it part of the OLAP engine. What i want to know is do I need OLAP installed to use these functions

SELECT last_name, hire_date, salary,

   LAG(salary, 1, 0) OVER (ORDER BY hire_date) AS prev_sal    FROM employees
   WHERE job_id = 'PU_CLERK';

Cheers
