-- File name: one_sql_time_series.sql
--
-- Purpose: Performance History for one SQL
--
-- Author: Carlos Sierra
--
-- Version: 2014/10/31
--
-- Usage: Script sql_performance_changed.sql lists SQL Statements with performance
-- improvement or regressed over some History.
-- This script one_sql_time_series.sql lists the Performance Time Series for
-- one SQL.
--
-- Parameters: SQL_ID
--
-- Example: @one_sql_time_series.sql
--
-- Notes: Developed and tested on 11.2.0.3.
--
-- Requires an Oracle Diagnostics Pack License since AWR data is accessed.
--
-- To further investigate poorly performing SQL use sqltxplain.sql or sqlhc
-- (or planx.sql or sqlmon.sql or sqlash.sql).
