[20210112]ashtop查詢特定表的SQL語句.txt

--//ashtop.sql是Tanel Poder大師寫的檢視  Display top ASH time 的指令碼,它非常靈活.
--//例如有時候最佳化我要集中精力最佳化特定表的相關語句,這樣可以統籌考慮索引的建立,執行如下:

@ ashtop username,sql_id,module,machine "sql_id in (select sql_id from v$sqlarea where lower(sql_text) like '%ms_cf01%')" trunc(sysdate) sysdate

--//這樣有一個缺點就是sql_text 定義為VARCHAR2(1000),應該換成sql_fulltext欄位.
--//toad下查詢有一個缺點僅僅查詢sql_text欄位.

--//我自己在ashtop基礎上寫一個指令碼如下:

$ cat ashtable.sql
column module format a30
prompt
prompt @ tpt/&&1.ashtop username,sql_id,module "&&3 and sql_id in (select sql_id from v$sqlarea where lower(sql_fulltext) like lower('%&&2%'))"  &&4 &&5
prompt
@ tpt/&&1.ashtop username,sql_id,module "&&3 and sql_id in (select sql_id from v$sqlarea where lower(sql_fulltext) like lower('%&&2%'))"  &&4 &&5

--//簡單說明:
--//引數1 '' d ,''表示執行ashtop,d 表示執行dashtop.
--//引數2 查詢相關的表
--//引數3 補充查詢條件
--//引數4,5 查詢時間範圍.我一般選擇查詢trunc(sysdate-1) sysdate,這樣簡單一些.
--//如果打入具體時間最好不要有空格 ,選擇yyyymmddhh24miss格式.
--//寫成 "to_date('20210112080000','yyyymmddhh24miss')" "to_date('20210112090000','yyyymmddhh24miss')"
--//我自己定義3個alias:
alias zdate='date +"%Y/%m/%d %T"'
alias zzdate="date +'trunc(sysdate)+%H/24+%M/1440+%S/86400 == %Y/%m/%d %T'"
alias zzzdate="date +'%Y%m%d%H%M%S'"

$ zdate ;zzdate ;zzzdate
2021/01/12 16:03:53
trunc(sysdate)+16/24+03/1440+53/86400 == 2021/01/12 16:03:53
20210112160353
--//可以選擇第2種格式,這樣不容易錯.
SCOTT@book> select trunc(sysdate)+16/24+03/1440+53/86400 aa from dual ;
