SELECT query taking long time

Hi All,
I am trying to run one SELECT statement which uses 6 tables. That query generally take 25-30 minutes to generate output.
Today it is running from more than 2 hours. I have checked there are no locks on those tables and no other process is using them.
What else I should check in order to figure out why my SELECT statement is taking time?
Any help will be much appreciated.
Thanks!

Please let me know if you still want me to provide all the information mentioned in the link.Yes, please.
Before you can even start optimizing, it should be clear what parts of the query are running slow.
The links contains the steps to take regarding how to identify the things that make the query run slow.
Ideally you post a trace/tkprof report with wait events, it'll show on what time is being spent, give an execution plan and a database version all in once...
Today it is running from more than 2 hours. I have checked there are no locks on those tables and no other process is using them.Well, something must have changed.
And you must indentify what exactly has changed, but it's a broad range you have to check:
- it could be outdated table statistics
- it could be data growth or skewness that makes Optimizer choose a wrong plan all of a sudden
- it could be a table that got modified with some bad index
- it could be ...
So, by posting the information in the link, you'll leave less room for guesses from us, so you'll get an explanation that makes sense faster or, while investigating by following the steps in the link, you'll get the explanation yourself.

Select Query taking long time to run second time

Hi All,
I have Oracle 11gR1 in windows server 2008 R2 .
I have some tables with 10 million records . When i run the select query for those tables first time it gives me result in 15 seconds but if i am running the same script second time from the same session I am getting the result in 15 minutes to complete ..
Why it is happening? What may be the solution for this ?
Thanks & Regards,

Hi Mohamed,
I just saw that both the times for the same query execution plan is different ..
here are the details :
First time Second Time
g84m3qqjv2p3q g84m3qqjv2p3q
2733045235 1310485984
So plz tell me how should i force database to use the first execution plan ?
I got this script for forcing the Db to use the same execution plan

First select - mixed order of fields. Response time: 82.155 microseconds for 39380 records selected.
Second select - fields in the order of the table. Response time: 81.061 microseconds for the same 39380 records selected.
Then I changed the order of SELECT statements. I have put first the select with ordered fields, and second - select with mixed order of fields. The runtimes were the following:
Ordered fields - 82.649 microseconds
Mixed order of fields - 80.270 microseconds.

I have some suggestions. But first, you realize that you have some redundant indexes, right? You have an index on account(account_name) and also account(account_name, account_id), and also account_history(invoice_id) and account_history(invoice_id, adjustment_id). No matter, I will suggest some new composite indexes.
Also, you do not need two lines for these conditions:
and round(a.account_balance, 2) > 0
AND a.account_balance > 0
You can just use: and a.account_balance >= 0.005
So the formatted query isselect a.account_id,
       round(a.account_balance, 2) account_balance,
       nvl(ah.invoice_id, ah.adjustment_id) transaction_id,
       to_char(ah.effective_start_date, 'DD-MON-YYYY') transaction_date,
       to_char(nvl(i.payment_due_date, to_date('30-12-9999', 'dd-mm-yyyy')),
               'DD-MON-YYYY') due_date,
       ah.current_balance - ah.previous_balance amount,
       decode(ah.invoice_id, null, 'A', 'I') transaction_type
from account a, account_history ah, invoice i
where a.account_id = ah.account_id
   and a.account_type_id = 1000002
   and (ah.invoice_id is not null or ah.adjustment_id is not null)
   and ah.CURRENT_BALANCE > ah.previous_balance
   and ah.invoice_id = i.invoice_id(+)
   AND a.account_balance >= .005
order by a.account_id, ah.effective_start_date desc;You will probably want to select:
1. From ACCOUNT first (your smaller table), for which you supply a literal on account_type_id. That should limit the accounts retrieved from ACCOUNT_HISTORY
2. From ACCOUNT_HISTORY. We want to limit the records as much as possible on this table because of the outer join.
3. INVOICE we want to access last because it seems to be least restricted, it is the biggest, and it has the outer join condition so it will manufacture rows to match as many rows as come back from account_history.
Try the query above after creating the following composite indexes. The order of the columns is important:create index account_composite_i on account(account_type_id, account_balance, account_id);
create index acct_history_comp_i on account_history(account_id, invoice_id, adjustment_id, current_balance, previous_balance, effective_start_date);
create index invoice_composite_i on invoice(invoice_id, payment_due_date);All the columns used in the where clause will be indexed, in a logical order suited to the needs of the query. Plus each selected column is indexed as well so that we should not need to touch the tables at all to satisfy the query.
Try the query after creating these indexes.
A final suggestion is to try larger sort and hash area sizes and a manual workarea policy.alter session set workarea_size_policy = manual;
alter session set sort_area_size = 2147483647;
alter session set hash_area_size = 2147483647;

Select query takes long time....

Hi Experts,
I am using a select query in which inspection lot is in another table and order no. is in another table. this select query taking very long time, what is the problem in this query ? Pl. guide us.

and b~typ = '3'
and a~bwart = '321'
and a~aufnr in aufnr1.
Yusuf

hi
instead of using 'move to corresponding of itab' fields use 'into table itab'.....
coz......if u use move to corresponding it will search for all the appropriate fields then it will place u r data........instead of that declare apprpiate internal table and use 'into table itab'.
and one more thing dont use joins ......coz joins will decrease u r performance .....so instead of that use 'for all entries' ....and mention all the key fields in where condition ........
ok

CDHDR table query taking long time

Hi all,
Select query from CDHDR table is taking long time,in where condition i am giving OBJECTCLASS = 'MAT_FULL' udate = sy-datum and langu = 'EN'.
any suggestion to improve the performance.i want to select all the article which got changed on current date
regards
shibu

This will always be slow for large data volumes, since CDHDR is designed for quick access by object ID (in this case material number), not by date.
I'm afraid you would need to introduce a secondary index on OBJECTCLAS and UDATE, if that query is crucial enough to warrant the additional disk space and processing time taken by the new index.
Greetings

Select query running long time

Hi,
DB version : 10g
platform : sunos
My select sql query running long time (more than 20hrs) .Still running .
Is there any way to find sql query completion time approximately. (Pending time)
Also is there any possibilities to increase the speed of sql query (already running) like adding hints.
Please help me on this .
Thanks

Hi Sathish thanks for your reply,
I have already checked in V$SESSION_LONGOPS .But it's showing TIME_REMAINING -->0

Oracle SQL Select query takes long time than expected.

Hi,
I am facing a problem in SQL select query statement. There is a long time taken in select query from the Database.
The query is as follows.
select /*+rule */ f1.id,f1.fdn,p1.attr_name,p1.attr_value from fdnmappingtable f1,parametertable p1 where p1.id = f1.id and ((f1.object_type ='ne_sub_type.780' )) and ( (f1.id in(select id from fdnmappingtable where fdn like '0=#1#/14=#S0058-3#/17=#S0058-3#/18=#1#/780=#5#%')))order by f1.id asc
This query is taking more than 4 seconds to get the results in a system where the DB is running for more than 1 month.
The same query is taking very few milliseconds (50-100ms) in a system where the DB is freshly installed and the data in the tables are same in both the systems.
Kindly advice what is going wrong??

Sql query taking long time

the below query is taking very long time.
select /*+ PARALLEL(a,8) PARALLEL(b,8) */ a.personid,a.winning_id, b.questionid from
winning_id_cleanup a , rm_personquestion b
where a.personid = b.personid and (a.winning_id,b.questionid) not in
(select /*+ PARALLEL(c,8) */ c.personid,c.questionid from rm_personquestion c where c.personid=a.winning_id);
where the rm_personquestion table is having 45 million rows and winning_id_cleanup is having 1 million rows.
please tell me how to tune this query?

Please post u'r query at PL/SQL

Select query taking more time..

Hi friends..
The below inner join statement is taking more time , can any body sugget me to improve the performance . I tried FOR ALL ENTRIES also but that also taking more time than inner join statement .
SELECT a~vbeln from vbap as a inner join vakpa as b
      on avbeln = bvbeln
      into corresponding fields of table IT_VAKPA
      where a~WERKS IN S_IWERKS
      and a~pstyv NE 'ZRS'
      and b~vkorg = IVKORG
      and b~audat IN IAUDAT
      and b~vtweg IN IVTWEG.
Regards
Chetan

Hi Chetan ,
VAKPA is an index table. From the select query , it has been observed that you are not fetching any data from VAKPA. Only you have added some selection paramenters in where clause of select query.
My suggestion will be instead of using VAKPA in inner join you use VBAK along with VBAP. All the fields that you are using as selection condition from VAKPA are there in VBAK.
I am sure performance of query will be improved.
If still duo to business logic you need to use VAKPA, try to create secondary non unique index on fields VKORD,AUDATand VTWEG on table VAKPA.
However I will recommend you to go for first option only. If this does not work then go for second option.
Hopfully this will help you.

Nikhil

Query taking long time

Hi
I have a query in which, its a 3 table join but takes a long time to execute. I had checked with plan table.. it shows one of the table is FULL ACCESS.
I have 2 clarifications.
1. Will the status checking as NULL - (it shouldn't use index)
2. Is the case statements are recommended for queries.
Query
Select .........
FROM CLIENT LEFT OUTER JOIN INTERNET_LOGIN ON INTERNET_LOGIN.NUM_CLIENT_ID=CLIENT.NUM_CLIENT_ID,
POLI_MOT.
WHERE
POLI_MOT.NUM_CLIENT_ID=CLIENT.NUM_CLIENT_ID
AND
(POLI_MOT.CHR_CANCEL_STATUS='N'
OR
POLI_MOT.CHR_CANCEL_STATUS IS NULL)
AND
CLIENT.NUM_CONTACT_TYPE_ID IN (1,3)
AND
(NVL(POLI_MOT.VCH_NEW_IC_NO,'A') =
CASE WHEN (NVL(null,NULL) IS NULL) THEN
NVL(POLI_MOT.VCH_NEW_IC_NO,'A')
ELSE
NVL(null,NULL)
END
OR
POLI_MOT.VCH_OLD_IC_NO =
CASE WHEN nvl(null,null) IS NULL THEN
POLI_MOT.VCH_OLD_IC_NO
ELSE
NVL(null,NULL)
END )
AND POLI_MOT.VCH_POLICY_NO =
CASE WHEN UPPER(nvl(NULL,null)) IS NULL THEN
POLI_MOT.VCH_POLICY_NO
ELSE
NVL(NULL,NULL)
END
AND POLI_MOT.VCH_VEHICLE_NO =
CASE WHEN UPPER(NVL('123',NULL)) IS NULL THEN
POLI_MOT.VCH_VEHICLE_NO
ELSE
NVL('123',NULL)
END

Hi,
There is nothing wrong in having a full table access. When you do the explain plan please check for which table costs you the maximun. try to work on that table.
To tune the performance of your query you can try either indexing or parallel access.
the syntax for parallel index is
/*+ PARALLEL("TBL_NM",100) */(any number)...
for index please use the index name of the table you want to index..
