Hi,

I am trying to find a particular sql (using sql id) executions hourly and daily counts for the last 30 days. Can anyone has command please?

I have tried with dba_hist_active_sess_history and dba_hist_sqlstat for the last 1 hour to test if it gives correct result. But the output doesn't match with sum of counts in each instance taken from awrsqlrpt.sql

Thanks,
Suresh

Why do you expect every SQL that was ever executed to be in the HISTORY views?
What does the documentation say regarding the content of these views?

I am looking for only one particular query (I have sql id of that query) and I see information related to that sql in dba_hist_active_sess_history. Since it is ASH data and counts are not accurate based on number of rows of the query in history tables, I am facing problem in aggregating the sql count hourly and daily. Could you please provide a query to get the counts? Thanks!

What I know is blah, blah blah from you.
Is COPY & PASTE broken for you?
I don't know what you have.
I don't know what you do.
I don't know what you see.
I don't know what you want.

nh3bg8aq 9/30/2019 01:00 1704
nh3bg8aq 9/30/2019 02:00 6729

I reverse-engineered the AWR report code (well ok, ok, I just sql-traced it) and came up with the following.

However, remember that SQL_ID CAN and DO change, especially when you bounce the server or the shared pool is flushed.

select
   S.begin_interval_time,
   s.end_interval_time,
   T.executions_total
from
   AWR_PDB_sqlstat T,
   DBA_HIST_SNAPSHOT S 
where
   T.sql_id = 'fg0kvac1dkzw5'  -- Insert your own SQL_ID here
   and s.snap_id = t.snap_id
order by 1 desc;

Thanks JP. I found a way to get the details using DBA_HIST_SQLSTAT and DBA_HIST_SNAPSHOTS. However, I will try your query and compare if it see any difference in results.
