转一段网友回复：

Hi there,

It is just a quick idea. I have suspicious that ad_applied_patches
contains information about patches that you applied on the system,
ad_bugs has information about all bugs and patches that have been
included in the patches you applied.

For example you apply merged patch merge123 it contains 5 patches
10001 10002 10003 …
ad_applied_patches – will have one record about merge123
ad_bugs – 5 records

Another example: you apply maintenance patch which includes 51 other
patches. In that case
ad_applied_patches – will have one record about maintenance patch
ad_bugs – 51 + 1

I hope my thought is clear for you.

PS Anyway I use ad_bugs table in order to find out do I have one or
another patch to apply.

select count(bug_number) from apps.ad_bugs; bug_number 对应 patch号

ad_applied_patches是你自己adpatch打的那些（包括merge），但是安装的时候已经包含的patch,这个表不会记录，

所以如果要查询某个patch是否已经applied，还是ad_bugs。

select b.bug_number, to_char(b.LAST_UPDATE_DATE, 'YYYY-MM-DD HH24:MI:SS') Last_update from apps.ad_bugs b where bug_number='&a';
Filename [adpatch.log] : 10257769_EN_adpatch.log(指定adpatch输出日志的名字，一般放在$APPL_TOP/admin/<SID>/log下，默认名为adpatch.log，不过最好改成补丁编号+语言.log)

set lines 200 pages 50000
select distinct b.bug_number, to_char(b.LAST_UPDATE_DATE, 'YYYY-MM-DD') Last_update from apps.ad_bugs b where to_char(b.LAST_UPDATE_DATE, 'YYYY-MM-DD')>'2010-08-20' order by 2;
