HI Experts,

Could you please help me to tune this query and also needs to order by event_minute.



select /*ALL_ROWS*/
TO_CHAR(EVENT_MINUTE, 'MM-YYYY') AS EVENT_MINUTE,
PROCESS_NAME,
substr(

XMLCast(
XMLAgg(

XMLElement(e, ','||CONTRACT)

order by CONTRACT
)
as clob
), 2
) CONTRACT_LIST,
APPLICATION AS APPLICATION,
SUM(TOTAL_COUNT) AS TOTAL_COUNT,
SUM(TOTAL_COUNT)-SUM(COUNT_FAILED) AS SUCCESS_TRANS,
ROUND(AVG(AVG_DURATION),2) AS AVG_DURATION,
ROUND((SUM(TOTAL_COUNT)-SUM(COUNT_FAILED))/SUM(TOTAL_COUNT)*100) AS SUCCESS_PERCENTAGE
FROM STATS_TRACK_SUMMARY_BY_MIN
WHERE EVENT_MINUTE >= ADD_MONTHS(TRUNC (SYSDATE,'MM'), - 3)
AND contract <> 'NULL'
AND APPLICATION IN ('cap','CAP')
and process_name='ws_router'
GROUP BY
TO_CHAR(EVENT_MINUTE, 'MM-YYYY'),
APPLICATION,
PROCESS_NAME
union all
select
TO_CHAR(EVENT_MINUTE, 'MM-YYYY') AS EVENT_MINUTE,
PROCESS_NAME,
to_clob( contract),
APPLICATION AS APPLICATION,
SUM(TOTAL_COUNT) AS TOTAL_COUNT,
SUM(TOTAL_COUNT)-SUM(COUNT_FAILED) AS SUCCESS_TRANS,
ROUND(AVG(AVG_DURATION),2) AS AVG_DURATION,
ROUND((SUM(TOTAL_COUNT)-SUM(COUNT_FAILED))/SUM(TOTAL_COUNT)*100) AS SUCCESS_PERCENTAGE
FROM STATS_TRACK_SUMMARY_BY_MIN
WHERE EVENT_MINUTE >= ADD_MONTHS(TRUNC (SYSDATE,'MM'), - 3)
AND contract <> 'NULL'
AND APPLICATION IN ('cap','CAP')
and process_name!='ws_router'
GROUP BY
TO_CHAR(EVENT_MINUTE, 'MM-YYYY'),
APPLICATION,
PROCESS_NAME,
contract

1) tune
If only a sql can be formatted so it would be readable..

2) order by
SQL> select * 
     from   bla;

        ID
----------
         1
         2
         3
         4

SQL> select id from bla where id>2 
       union all 
     select id from bla where id<3;

        ID
----------
         3
         4
         1
         2

SQL> select id from bla where id>2 
       union all 
     select id from bla where id<3 
     order by id;

        ID
----------
         1
         2
         3
         4

SQL>
Maybe the above example may shine some light.

Welcome to the forum.
Please read the OraFAQ Forum Guide and How to use [code] tags and make your code easier to read.
Indent the code, use code tags and align the columns in result.

Also always post your Oracle version, with 4 decimals (query v$version), as often solution depends on it.

Can you provide what is asked in the way it is asked.

John Watson wrote on Sun, 26 April 2020 15:38
If you persist in ignoring Forum Guidelines, you are unlikely to get any assistance. Please format your code (there is a code formatting tool here, http://www.dpriver.com/pp/sqlformat.htm ) and enclose the code you post in [code] tags, as described here, http://www.orafaq.com/forum/m/673006/#msg_673006

BHA, is your obnoxious behaviour is deliberate? You are repeatedly making posts that are not properly formatted. This looks very like trolling: being rude in an attempt to make people angry. Please stop flooding the forum with rubbish.

I shall lock this topic.

Michel Cadot wrote on Mon, 27 April 2020 10:16

In the end, it seems you are just a troll trying to make people angry.
This topic is locked.
Come back with a proper request in another topic.

Dito.
