1. 先执行xplan.sql脚本
-- ----------------------------------------------------------------------------------------------
--
-- Script: xplan.sql
--
-- Author: Adrian Billington
--
--
-- Description: Creates a package named XPLAN as a wrapper over DBMS_XPLAN. Provides access to
-- the following DBMS_XPLAN pipelined functions:
--
-- 1. DISPLAY;
-- 2. DISPLAY_CURSOR;
-- 3. DISPLAY_AWR (optional - see Notes section for licence implications).
--
-- The XPLAN wrapper package has one purpose: to include an "order" column in the
-- plan output to show the order in which plan operations are performed. See the
-- following example for details.
--
-- Example: DBMS_XPLAN output (format BASIC):
-- ------------------------------------------------
-- | Id | Operation | Name |
-- ------------------------------------------------
-- | 0 | SELECT STATEMENT | |
-- | 1 | MERGE JOIN | |
-- | 2 | TABLE ACCESS BY INDEX ROWID| DEPT |
-- | 3 | INDEX FULL SCAN | PK_DEPT |
-- | 4 | SORT JOIN | |
-- | 5 | TABLE ACCESS FULL | EMP |
-- ------------------------------------------------
--
-- Equivalent XPLAN output (format BASIC):
-- --------------------------------------------------------
-- | Id | Order | Operation | Name |
-- --------------------------------------------------------
-- | 0 | 6 | SELECT STATEMENT | |
-- | 1 | 5 | MERGE JOIN | |
-- | 2 | 2 | TABLE ACCESS BY INDEX ROWID| DEPT |
-- | 3 | 1 | INDEX FULL SCAN | PK_DEPT |
-- | 4 | 4 | SORT JOIN | |
-- | 5 | 3 | TABLE ACCESS FULL | EMP |
-- --------------------------------------------------------
--
-- Usage: SELECT * FROM TABLE(XPLAN.DISPLAY(...));
-- SELECT * FROM TABLE(XPLAN.DISPLAY_CURSOR(...));
-- SELECT * FROM TABLE(XPLAN.DISPLAY_AWR(...));
--
-- Usage for XPLAN is exactly the same as for DBMS_XPLAN. See the DBMS_XPLAN
-- documentation for all options.
--
-- Note that the only exception to this is that XPLAN.DISPLAY does not contain
-- the FILTER_PREDS parameter available in 10.2+ versions of DBMS_XPLAN.DISPLAY
-- (this parameter enables us to limit the data being returned from an Explain
-- Plan but is of quite limited use).
--
-- See the Notes section for details on the licensing implications of using
-- XPLAN.DISPLAY_AWR.
--
-- Versions: This utility will work for all versions of 10g and upwards.
--
-- Required: 1) PLAN_TABLE of at least 10.1 format
--
-- 2) Either:
-- SELECT ANY DICTIONARY
-- Or:
-- SELECT on V$DATABASE
-- SELECT on V$SQL_PLAN
-- SELECT on V$SESSION
-- SELECT on V$MYSTAT
-- SELECT on DBA_HIST_SQL_PLAN
--
-- 3) CREATE TYPE, CREATE PROCEDURE
--
-- Notes: *** IMPORTANT: PLEASE READ ***
--
-- 1) Oracle license implications
-- ---------------------------
-- The AWR functionality of XPLAN accesses a DBA_HIST% view which means
-- that it requires an Oracle Diagnostic Pack license. The XPLAN.DISPLAY_AWR
-- pipelined function is therefore disabled by default. It can be included
-- by modifying two substitution variables at the start of the script. Please
-- ensure that you are licensed to use this feature: the author accepts
-- no responsibility for any use of this functionality in an unlicensed database.
--
-- Installation: Installation requires SQL*Plus or any IDE that supports substitution
-- variables and SQL*Plus SET commands. To install, simply run the script in
-- the target schema.
--
-- Creates: 1) XPLAN_OT object type
-- 2) XPLAN_NTT collection type
-- 3) XPLAN package
--
-- Removal: 1) DROP PACKAGE xplan;
-- 3) DROP TYPE xplan_ntt;
-- 4) DROP TYPE xplan_ot;
--
--
-- ----------------------------------------------------------------------------------------------
--
-- Define the "commenting-out" substitution variables for the AWR elements of this utility. The
-- default is commented out. To include the AWR functionality, change the variables to " " (i.e.
-- a single space).
