Need to tune the below query.
Query below:
I have generated the explain plan for the same and its cost is overall 2089...
But Strange once I have removed the "ORDER SIBLINGS BY RETAILER_NM" from below then its cost is coming overall 40.
Can U suggest me what is the best solution.
SELECT path as Retailer_id, logical_physical_flg, parent_retailer_id, upper(retailer_nm), max_level
FROM (SELECT A.RETAILER_ID,LOGICAL_PHYSICAL_FLG, NULL AS PARENT_RETAILER_ID, B.RETAILER_NM, a.retailer_id path,
(LEVEL+2) AS MAX_LEVEL FROM
RETAILER B, USER_RETAILER_MAP A WHERE USER_ID= 'ALEX.CAYLESS@GMACIO' AND
B.RETAILER_ID=A.RETAILER_ID AND B.STATUS='ACTIVE' AND
A.RETAILER_ID NOT IN (SELECT DISTINCT RETAILER_ID FROM

Do I need to tune the base query of my materialized view ?
Hi gurus,
We implement materialized view (FAST REFRESH ON COMMIT) on base table used in OLTP system. In fact the MV itself is also queried by the OLTP system itself, interactively.
Currently user complain that after they input transaction, they see that the MV is not refresh as soon as they commit the transaction.
(it takes 5 to 10 minutes before they see the update on the MV)
The query of the MV is attached below, it consists of union all of two queries but actually the real query has 13 queries on a UNION ALL.
The question is :
Do I need to tune the query that forms the MV ?
Does it impact the refresh time of the MV ?
Thank you for your help,

......Hi Justin & APC,
Are they seeing a 5-10 minute delay in being able to commit their transaction?NO, the commit itself is completed normally, but after that when they go to the page (this is webbased app) that display data from the MV, the newly committed transactionis not there yet. Only after 5-10 minutes we can see the new data.
What does the F_Convert_Qty_K() function do?It is a function that convert the quantity from whatever Unit Of Measurement (UOM) into the smallest UOM. Below is the code.
So the question remains:
why intermittently theere is delay before the new data visible in the MV ?
Thanks you,
xtanto

Hi All,
I've a query given below..

I would like to get All the data which status =closed in the month of Oct for Old rate,
So for this i am writing the query above. But not getting the o/p.

Welcome to the forum!
Depending on your data and your requirements:

SELECT column_1, column_2, column_3, column_4
, TO_DATE ( substr (column_3, 1, 4)

) AS time_4
FROM table_x

SELECT column_1, column_2, column_3, column_4
, time_3, time_4
, time_4 - SUM (time_4 - time_3) OVER ( PARTITION BY column_1
ORDER BY time_3
) AS grp_id
FROM got_times
SELECT column_1

FROM got_grp_id
GROUP BY column_1

ORDER BY column_1

;Whenever you have a problem, please post CREATE TABLE and INSERT statements for your sample data, as well as the results you want from that data. Explain, with specific examples, how you get the results you want from that data.
Always say which version of Oracle you're using. The query above will work in Oracle 9.1 (and higher).
Since this is your first thread, I'll do this for you:
CREATE TABLE table_x
( column_1 NUMBER
, column_2 NUMBER
, column_3 VARCHAR2 (5)
, column_4 VARCHAR2 (5)
INSERT INTO table_x (column_1, column_2, column_3, column_4) VALUES (253800, .25, '0845A', '0900A');
INSERT INTO table_x (column_1, column_2, column_3, column_4) VALUES (253800, 1, '0900A', '1000A');
INSERT INTO table_x (column_1, column_2, column_3, column_4) VALUES (253800, 1, '1300P', '1400P');
INSERT INTO table_x (column_1, column_2, column_3, column_4) VALUES (253800, 1, '1500P', '1600P');
INSERT INTO table_x (column_1, column_2, column_3, column_4) VALUES (253800, 1, '1600P', '1700P');Column_1 identifes a day.
Column_2 is an amount that I need to total.
Column_3 and column_4 are starting and ending times. We can assume that they are all valid times (in 'HH24MI' format, plus a redundant 'A' or 'P') on the same day, column_3 is always less than column_4, and that the range of two rows for the same value of column_1 never overlap. Column_4 of one row may be equal to column_3 of another rows with the same column_1, but it will never be greater.
Each row of the output represent a contiguous group of rows (each ending exactly when the next one begins) with the same column_1, with the common column_1, the total of column_2, and the range of the group.
For example, the first two rows for a single group, because they have the same value for column_1, and one ends exactly when the other begins (at 9:00 AM). This group represents day 253800, from 8:45 AM to 10:00 AM. The totla of column_2 fro this group is .25 + 1 = 1.25.
The next row (from 1:00 PM to 2:00 PM) is a group all by itself, because there is a gap one either side of it separating it from its nearest neighbor on the same day."
Of course, I'm guessing at lots of things.

158 rows selected.ThanksSo this is a VIEW with I think 18 tables (I may have missed one or two), some of which are referenced more than one. Some of these tables have tens of miilions of rows. What exactly are you expecting from us?
I guess this is a data warehouse or BI query. Sometimes such queries just take an age to run and there's nothing which can be done except result caching. Other times the queries can be tuned, but iit requires way more context and domain knowledge than you have provided.
Please start by reading [url https://forums.oracle.com/forums/thread.jspa?threadID=2174552#9360003]this FAQ. .

Need to tune the hierarchical query
Hi Guys,
Can you guys tune in the possible ways...as this is taking 30-40 sec.. No indexes on this table as of now.
SELECT org_id,
parent_id,
organization,
(SELECT LISTAGG(parent_id, ', ') WITHIN GROUP( ORDER BY org_id)
FROM organization_master where org_id in(SELECT org_id
FROM organization_master
START WITH org_id = a.org_id
CONNECT BY NOCYCLE prior parent_id = org_id))
FROM t_org a
WHERE upper(organization) like upper('%Greater%');
Thanks in advance!
Rgds,
LrkSo this is a VIEW with I think 18 tables (I may have missed one or two), some of which are referenced more than one. Some of these tables have tens of miilions of rows. What exactly are you expecting from us?
I guess this is a data warehouse or BI query. Sometimes such queries just take an age to run and there's nothing which can be done except result caching. Other times the queries can be tuned, but iit requires way more context and domain knowledge than you have provided.
Please start by reading [url https://forums.oracle.com/forums/thread.jspa?threadID=2174552#9360003]this FAQ. .

Need Help with the below query
Hi All,
I'm working on Oracle HRMS tables which have date tracking facility.
I'm working on Oracle 10G.
I have a table per_all_assignments_f(seeded) which contains the employee related information.
It has normal hours and the assignment_id(primary key) in the table
The data is something like
assignment_id
123 30 01-Jan-2000 31-dec-2009
123 32 01-Jan-2010 31-dec-2012
123
assignment_id
Normal_hours
Effective_start_Date
Effective_end_Date
123
30
01-Jan-2000
31-dec-2009
123
32
01-Jan-2010
31-dec-2012
123
40
01-Jan-20103
40 01-jan-2013 31-dec-4712
Now I'd like to pass the latest date(sysdate) to a function which should give me the
last changed normal hours as on today. In this case 32.
select normal_hours from per_all_assignments_f where
assignment_id=123
and trunc(latest_date) between effective_start_date and effective_end_date
This will give me the latest normal hours of 40 but I want the last changed hours irrespective of how many ever be the changes.
hope I'm clear in specifying my requirement.
Appreciate your time
Thanks,

How PK value is repeating in your sample data!

Nope. What is "changed hours"? Not able to break your source code! a tough one, I say.
By the way, follow the link shared by Karthick and will be easy to answer for anyone.
Thanks! -

Do I need to tune the redo log? Each of redo log file is 50MB. It switched more frequent when there are not many users than real busy hours.
nullSelect may or may not generate redo. Delayed block cleanout is one of the reasons for a query to produce redo: https://metalink.oracle.com/metalink/plsql/f?p=130:14:2631437878498686237::::p14_database_id,p14_docid,p14_show_header,p14_show_help,p14_black_frame,p14_font:NOT,40689.1,1,1,1,helvetica#aref1
Another reason is locking the rows with "for update":
SQL> create table t1 as select * from all_objects;
Table created.
SQL> set autot trace stat
SQL> select * from t1;

You can't use 'c_rank' in the where clause because it doesn't exist; you are computing it in the SELECT clause.
Remove the last condition and wrap your query in another one to select by 'c_rank'. -

end) sal from emp_test
