--
-- sql_id: the sql_id of the statement to attach the profile to (must be in the shared pool)
--
-- child_no: the child_no of the statement from v$sql
--
-- profile_name: the name of the profile to be generated
--
-- category: the name of the category for the profile
--
-- force_macthing: a toggle to turn on or off the force_matching feature
--
-- Description:
--
-- Based on a script by Randolf Giest.
