----------------------------------------------------------------------------------------
-- SEE DOC at C:\My personal work Related\MY STUFF\perf notes\Single Hint SQL Profiles
--
-- File name:   create_1_hint_sql_profile.sql
--
-- Purpose:     Prompts for a hint and makes a profile out of it.
-
-- Author:      Kerry Osborne
--
-- Usage:       This scripts prompts for four values.
--
--              profile_name: the name of the profile to be attached to a new statement
--
--              sql_id: the sql_id of the statement to attach the profile to 
--                      (the statement must be in the shared pool)
--
--              category: the category to assign to the new profile 
--
--              force_macthing: a toggle to turn on or off the force_matching feature
--
--              hint_text: text to be used as a hint
--
-- Description: This script prompts for a hint. It does not validate the hint. It creates a 
--              SQL Profile with the hint test and attaches it to the provided sql_id.
--              This script should now work with all flavors of 10g and 11g.
--              
-- Updated:     This script now allows inclusion of quoted text in the hint.

--              See kerryosborne.oracle-guy.com for additional information.
