I have to collect the past execution plan of specific statement(which runs somewhere around midnight everyday).
Then I will have to compare the last execution plans of the 3 same statement . I run AWR stats collection every hour and have history upto 30 days.

I am trying to run the following but it is not showing me even the last 3 executions of specific statement ( identified by .... like '%SUBSCRIBED_PRODUCT.BUSINESS_AREA_ID=2%'.......)

SELECT to_char(sql_text),command,snap_id,timestamp FROM
(
SELECT X.SNAP_ID, X.SQL_ID,SQL_TEXT
,ROUND(X.ELAPSED_TIME/1000000/X.EXECUTIONS_DELTA,3) AVG_ELAPSED_TIME_SEC
,ROUND(X.CPU_TIME /1000000/X.EXECUTIONS_DELTA,3) AVG_CPU_TIME_SEC
,X.ELAPSED_TIME TOTAL_ELAPSED_TIME_MIC_SEC
,X.CPU_TIME TOTAL_CPU_TIME_MIC_SEC
,X.EXECUTIONS_DELTA EXECUTIONS
,decode(DHST.COMMAND_TYPE,3,'Select',47,'pl/sql',2,'Insert') command
,DHSP.timestamp
FROM
DBA_HIST_SQLTEXT DHST,
DBA_HIST_SQL_PLAN DHSP,
(SELECT DHSS.SNAP_ID,DHSS.SQL_ID SQL_ID,SUM(DHSS.CPU_TIME_DELTA) CPU_TIME, SUM (DHSS.ELAPSED_TIME_DELTA) ELAPSED_TIME
, SUM(DHSS.EXECUTIONS_DELTA) EXECUTIONS_DELTA
FROM DBA_HIST_SQLSTAT DHSS
AND PARSING_SCHEMA_NAME='CCDW'
GROUP BY DHSS.SQL_ID,DHSS.SNAP_ID
) X
WHERE X.SQL_ID=DHST.SQL_ID and X.EXECUTIONS_DELTA>0
and DHSP.SQL_ID=X.SQL_ID
ORDER BY AVG_ELAPSED_TIME_SEC DESC
)
WHERE upper(DBMS_LOB.Substr(sql_text, 4000, 1)) like '%SUBSCRIBED_PRODUCT.BUSINESS_AREA_ID=2%'
group by to_char(sql_text),command,snap_id,timestamp
order by timestamp desc ;

Thanks,
Anurag Vidyarthi

sorry for typo, correct statement is as follows :

SELECT to_char(sql_text),command,snap_id,timestamp FROM
(
SELECT X.SNAP_ID, X.SQL_ID,SQL_TEXT
,ROUND(X.ELAPSED_TIME/1000000/X.EXECUTIONS_DELTA,3) AVG_ELAPSED_TIME_SEC
,ROUND(X.CPU_TIME /1000000/X.EXECUTIONS_DELTA,3) AVG_CPU_TIME_SEC
,X.ELAPSED_TIME TOTAL_ELAPSED_TIME_MIC_SEC
,X.CPU_TIME TOTAL_CPU_TIME_MIC_SEC
,X.EXECUTIONS_DELTA EXECUTIONS
,decode(DHST.COMMAND_TYPE,3,'Select',47,'pl/sql',2,'Insert') command
,DHSP.timestamp
FROM
DBA_HIST_SQLTEXT DHST,
DBA_HIST_SQL_PLAN DHSP,
(SELECT DHSS.SNAP_ID,DHSS.SQL_ID SQL_ID,SUM(DHSS.CPU_TIME_DELTA) CPU_TIME, SUM (DHSS.ELAPSED_TIME_DELTA) ELAPSED_TIME
, SUM(DHSS.EXECUTIONS_DELTA) EXECUTIONS_DELTA
FROM DBA_HIST_SQLSTAT DHSS
where PARSING_SCHEMA_NAME='CCDW'
GROUP BY DHSS.SQL_ID,DHSS.SNAP_ID
) X
WHERE X.SQL_ID=DHST.SQL_ID and X.EXECUTIONS_DELTA>0
and DHSP.SQL_ID=X.SQL_ID
ORDER BY AVG_ELAPSED_TIME_SEC DESC
)
WHERE upper(DBMS_LOB.Substr(sql_text, 4000, 1)) like '%SUBSCRIBED_PRODUCT.BUSINESS_AREA_ID=2%'
group by to_char(sql_text),command,snap_id,timestamp
order by timestamp desc ;

CUT & PASTE avoids typos
