Oracle EBS R12 - ad_bugs.BUG_NUMBER和ad_applied_patches.PATCH_NAME的关系

一般情况下一个patch修复一个bug,因此patch_name和bug_number是相等的,
但是如果某个patch merge了多了patch,那么该patch就具有了修复多个bug的效果,此时的patch_name和bug_number就不是一回事了.

表结构:

SQL> desc ad_bugs;
 Name                                      Null?    Type

在patch没有被merge的情况下,ad_bugs.BUG_NUMBER和ad_applied_patches.PATCH_NAME的值是相等的.

在patch被merge过的情况下,需要通过一个中间表(ad_comprising_patches)来关联ad_bugs.BUG_NUMBER和ad_applied_patches.PATCH_NAME,
而且此时的patch name默认是merge时的driver file name(如driver file  name是u_financial_merged.drv,那么patch name就是financial_merged).

关联层次:
ad_applied_patches -> ad_patch_drivers -> ad_comprising_patches -> ad_bugs

由于中间表ad_comprising_patches仅保存merged patch纪录,所以以下SQL只能查找到merged patch对应的patch name和bug number关联:

SELECT aap.patch_name
      ,aap.patch_type
      ,aap.last_update_date
      ,apd.driver_file_name
      ,apd.merged_driver_flag
      ,apd.merge_date
      ,ab.bug_number
      ,ab.last_update_date
FROM   ad_applied_patches aap
      ,ad_patch_drivers apd
      ,ad_comprising_patches acp
      ,ad_bugs ab
WHERE      aap.applied_patch_id = apd.applied_patch_id
       AND apd.patch_driver_id = acp.patch_driver_id
       AND acp.bug_id = ab.bug_id
     --  AND apd.merged_driver_flag = 'Y'

由于merge过的patch name没有实际意义,所以我们一般通过ad_bugs来验证某个patch是否已经打过了.

SELECT bug_number
      ,last_update_date
FROM   ad_bugs
WHERE  bug_number = '8644899';

对于重复安转的patch可通过以下SQL来查询安装历史纪录：

select orig_patch_name,last_update_date from ad_patch_drivers where applied_patch_id in 
(select applied_patch_id from ad_applied_patches where patch_name='17086303');   -- patch re-install
