结合AWR报告生成HTML格式的SQL执行计划
有些时候，我们需要分析占用资源比较大的sql的执行计划，也需要将sql的执行计划以报告的形式反馈给客户，由于AWR报告里的SQL通常都是些变量，因此以命令行方式生成sql的执行计划就很麻烦，而且也不美观，利用awrsqrpt.sql脚本就很方便。
生成HTML的执行计划很简单，如果是生成本地数据库的sql执行计划，执行awrsqrpt.sql就可以，但是如果需要生成由AWR迁移到本地数据库的分析数据，就需要使用awrsqrpi.sql。
SQL> @?/rdbms/admin/awrsqrpi

Specify the SQL Id
~~~~~~~~~~~~~~~~~~
输入 sql_id 的值: 8hm5s0k011450 --在AWR报告中看到的占用资源较大的SQL ID
SQL ID specified: 8hm5s0k011450
Specify the Report Name
~~~~~~~~~~~~~~~~~~~~~~~
The default report file name is awrsqlrpt_1_50063_50209.html. To use this name,
press
输入 report_name 的值: d:\stream.html --保存路径和名字
