Just taken a quick look anyway and you have a lot of nasty inline selects that would be better as joins...
Something like this... (untested)
SELECT HBD.HOTELBOOKINGID
     , HBD.ITEMREFERENCE
     , HBD.COUNTRYID
     , HBD.CITYID
     , HBD.LOCATIONID
     , HBD.CHECKINDATE
     , HBD.CHECKOUTDATE
     , HBD.NOOFNIGHTS
     , HBD.STARRATING
     , HBD.NOOFROOMS
     , HBD.CURRENCY
     , MAX(DECODE(CITYCM.PROVIDERID,2,CITYCM.CITYCODE)) AS GTACITYCODE
     , MAX(DECODE(CITYCM.PROVIDERID,4,CITYCM.CITYCODE)) AS HBCITYCODE

Help with query optimization

Right now my query takes anywhere from 30 to 60 sec's to execute. What should I do to cut this time down?
Here is my Query
select * from a , b, c
where a.a_seq = b.b_seq
and a.a_seq = c.c_seq
and a.a_type between 3 and 19
and a.detl_cod = 'AV'
and b.detl_stat = 'CLD'
and c.date is not null
and c.id != 92342
these tables have 100 thousand rows each. What should I be looking at to cut down the execution time on this query?

Sorry, I am fairly new to SQL. I can write queries but, I have no idea where to even begin with when it comes to checking performance. What are the statistics that you are mentioning? how will it effect performance? and what about indexed attributes? there are a lot of indexed attrinutes on each of these tables. I am unable to give you the exact tables because it is production application code(Cofidential).
I really appreciate any help from you
Thank you.

Help needed to optimize the query

Help needed to optimize the query:
The requirement is to select the record with max eff_date from HIST_TBL and that max eff_date should be > = '01-Jan-2007'.
This is having high cost and taking around 15mins to execute.
Can anyone help to fine-tune this??
   SELECT c.H_SEC,
                c.S_PAID,
                c.H_PAID,
                table_c.EFF_DATE
   FROM    MTCH_TBL c
                LEFT OUTER JOIN
                   (SELECT b.SEC_ALIAS,
                           b.EFF_DATE,
                           b.INSTANCE
                      FROM HIST_TBL b
                     WHERE b.EFF_DATE =
                              (SELECT MAX (b2.EFF_DATE)
                                 FROM HIST_TBL b2
                                WHERE b.SEC_ALIAS = b2.SEC_ALIAS
                                      AND b.INSTANCE =
                                             b2.INSTANCE
                                      AND b2.EFF_DATE >= '01-Jan-2007')
                           OR b.EFF_DATE IS NULL) table_c
                ON table_c.SEC_ALIAS=c.H_SEC
                   AND table_c.INSTANCE = 100;

To start with, I would avoid scanning HIST_TBL twice.
Try this
select c.h_sec
     , c.s_paid
     , c.h_paid
     , table_c.eff_date
from mtch_tbl c
left
join (
          select sec_alias
               , eff_date
               , instance
            from (
                    select sec_alias
                         , eff_date
                         , instance
                         , max(eff_date) over(partition by sec_alias, instance) max_eff_date
                      from hist_tbl b
                     where eff_date >= to_date('01-jan-2007', 'dd-mon-yyyy')
                        or eff_date is null
           where eff_date = max_eff_date
              or eff_date is null
       ) table_c
    on table_c.sec_alias = c.h_sec
   and table_c.instance = 100;

Reg Query Optimization - doubts..

Hi Experts,
This is related to Blog by Mr Prakash Darji regarding "Query Optimization" posted on Jan 26 2006.In this to optimize query Generation of Report is suggested.
I tried this, but I am not sure I am analyzing this correctly.
I collected Stats data before and after Generation of Report.But how to be sure that this is helping me? Did any one has tried this?
What to look for in Stats Data - duration?
But duration would not be absolute parameter as there is factor of "Wait Time, User", so duration may depend on this.
Please help me in this.
Thanks
Gaurav

SQL Server 2008R2 SP2 Query optimizer memory leak ?

It looks like we are facing a SQL Server 2008R2 queery optimizer memory leak.
We have below version of SQL Server
Microsoft SQL Server 2008 R2 (SP2) - 10.50.4000.0 (X64)
Jun 28 2012 08:36:30
Copyright (c) Microsoft Corporation

The instance is set MAximum memory tro 20 GB.
After executing a huge query (2277 kB generated by IBM SPSS Clementine) with tons of CASE and a lot of AND/OR statements in the WHERE and CASE statements and muliple subqueries the server stops responding on Out of memory in the internal pool
and the query optimizer has allocated all the memory.
From Management Data Warehouse we can find that the query was executed at
7.11.2014 22:40:57

On the other side MDW reports that the MEMORYCLERK_SQLOPTIMIZER increases since the execution of the query up to the point of OUTOF MEMORY, but the Average value is 54.7 MB during that period as can be seen on attached graph.
We have encountered this issue already two times (every time the critical query is executed).

Hi,
This does seems to me kind of memory Leak and actually it is from SQL Optimizer which leaked memory from buffer pool so much that it did not had any memory to be allocated for new page.

Can you post complete DBCC MEMORYSTATUS output which was generated in errorlog. Is this the only message in errorlog or there are some more messages before and after it.
select (SUM(single_pages_kb)*1024)/8192 as total_stolen_pages, type
from sys.dm_os_memory_clerks
group by typeorder by total_stolen_pages desc
and
select sum(pages_allocated_count * page_size_in_bytes)/1024,type from sys.dm_os_memory_objects
group by type
If you can post the output of above two queries with dbcc memorystaus output on some shared drive and share location with us here. I would try to find out what is leaking memory.
You can very well apply SQL Server 2008 r2 SP3 and see if this issue subsides but I am not sure whether this is fixed or actually it is a bug.

Any software for Query Optimization?

Hi,
Is there any software to be used for query Optimization
Please help me

3rd party tools suck (if they did not Oracle would incorporate them in its optimizer long ago). The best tools are:
1. Gather table and index statistics
2. Use CBO (FIRST_ROWS, ALL_ROWS)
3. SQL*Plus AUTOTRACE
4. EXPLAIN PLAN
5. SET SQL_TRACE = TRUE + TKPROF
6. Statspack
7. Enterprise manager (new Ora10g, did not try it)
All from Oracle...

The query processor ran out of stack space during query optimization. Please simplify the query

Can you suggest me that what should i do in this case.
Actually i am having one table that is a MasterTable.I am referring this table in more than 300 tables that means i am having foreign key of this primary key in 300+ tables.
due to this i am getting following error during deleting any row,
doesn't matter that data is existing in reference table or not.
Error that i am getting is
"The query processor ran out of stack space during query optimization. Please simplify the query"
Can you suggest me that what should i do to avoid this error,because i am unable to delete this entry.
Apart from it,i am getting performance problem too,so is it due to such huge FK on it.
Please suggest me on following points
1. Is it worst way to handle it,if yes then please suggest me solution for it.
2. If it is a correct way then what should i do if getting error during deleting any record.
3. Is it right to create Foreign key on each table where i am saving data of this master. if no then how to manage integrity.
4. What people do in huge database when they wants to create foreign key for any primary key.
5. Can you suggest me that how DBA's are handling this in big database,where they are having huge no. of tables.

The most common reason of getting such error is having more than 253 foreign key constraints on a table.
The max limit is documented here:
http://msdn.microsoft.com/en-us/library/ms143432(SQL.90).aspx
Although a table can contain an unlimited number of FOREIGN KEY constraints, the recommended maximum is 253. Depending on the hardware configuration hosting SQL Server, specifying additional foreign key constraints may be expensive for the query
optimizer to process. If you are on 32 bit, then you might want to move to 64 bit to get little bigger stack space but eventually having 300 FK is not something which would work in long run.

HFR - Data Query Optimization Settings

hi
In HFR, in a grid there are Data Query Optimization Settings, can you please help me on the settings property.
Our report fetches data using lot of attributes. When we don't use MDX setting, it fetches very fast, but the alias doesn't come.
However, when we use MDX setting, the alias comes, but the report takes lot of time to run(approx 1 min / row of data fetched)
Can you please guide on the same.
Thanks

Hi ,
I am working on below query optimization/Tuning.
SELECT
c_date,
c1,
c2,
c3,
c4,
c5,
c6
FROM tab1
WHERE
ROWNUM <= &param
AND ( c_date BETWEEN &date1 AND &date2 )
AND c3 in (
select c3
from tab2
where xxx='abc')
ORDER BY c1, c_date;
Note : &param,&date1 ,&date2 are parameters runtime getting from UI code .
tab1 having huge data around 10lacs to crores. and it has range partition on c_date column and subpartiotion on c1 column.
To get best throughput in less time, what i need to do ?
Please do let me know steps to tune/optimize the sql query.Also which hint we can use on sql query to better results.
Thanks in advanced.
PMBefore you start worrying about performance tuning you should worry about the query being incorrect.
         WHERE
             ROWNUM <= &param
             AND   ( c_date BETWEEN &date1 AND &date2 )
             AND c3 in (
                                         select c3
                                         from tab2
                                         where xxx='abc')
         ORDER BY c1, c_date;Presumably you want to limit the number of rows with the ROWNUM predicate AFTER the ORDER BY clause is applied.
Please read this and learn how queries are actually processed, I can almost guarantee you this query is not doing what you think it is doing at present.

Need Query Optimization Info

Hi Everyone:
I have a user on my site who's trying to find information on database query optimization. She's willing to pay $3 to someone who will give her some very basic information. I figured those of you who read this forum would have something handy you could just provide to her. It's not the information she's paying for, but the service of someone retrieving it for her. Would someone take a look? You can find her request here:
http://www.yepic.com/index.php?module=ContReq&hdnRequestID=8
The one problem is you have to register on the site before you can post your response. You just need to give create a username, email and password, though. It's very easy. I'd appreciate someone helping one of my users out.

. . . she's trying to avoid the
search taxSearch tax... never heard it put that way. I guess you are trying to avoid the "search engine" tax by advertising your site here? Maybe some one will help you out by answering the request from Corey for Search Engine Optimization.

SHIP_BUY.INSERT_DATE > '1-JAN-2007'
Like I said in your other thread about this, these two lines need to be fixed and your function needs to be fixed so the return statement doesn't do an implicit date conversion.
Can't you see what that first line is doing? You're taking a character string, turning it into a date, then back to a character string.
If nothing else, these lines should be...
F_GET_POD_RECEIVED_DATE (ship_BUY.SHIPMENT_GID) <= to_date('31-JUL-2013', 'DD-MON-YYYY')
SHIP_BUY.INSERT_DATE > to_date('01-JAN-2007','DD-MON-YYYY')
(assuming insert_date is a proper date format, fingers crossed)

Oracle 11g on Linux : Query Optimization issue

Hi guru,
I am facing one query optimization related problem in group by query
Table (10 million Records)
Product(ProductId number,ProductName varchar(100),CategoryId VARCHAR2(38),SubCategoryId VARCHAR2(38))
Index
create index idxCategory on Product (CategoryId,SubCategoryId)
Query1:To find product count for all CategoryId and SubCategoryId
select CategoryId,SubCategoryId,count(*) from Product group by CategoryId,SubCategoryId
Above query is not using index idxCategory and doing table scan which is very costly.
When I fire Query2: select count(*) from Product group by CategoryId,SubCategoryId
then it is properly using index idxCategory and very fast.
Even I specified hint in Query1 but it is not using hint.
Can anybody suggest why oracle is not using index in Query1 and what should I do so that Query1 will use Index.
Thanks in advance.

Can anybody suggest why oracle is not using index in Query1 and what should I do so that Query1 will use Index.The most obvious reason that the table needs to be visited would be that the columns "CategoryId" / "SubCategoryId" can be NULL but then this should apply to both queries. You could try the following to check the NULL issue:
select CategoryId,SubCategoryId,count(*) from Product where CategoryId is not null and SubCategoryId is not null group by CategoryId,SubCategoryId
Does this query use the index?
Can you show us the hint you've used to force the index usage and the EXPLAIN PLAN output of the two queries including the "Predicate Information" section? Use DBMS_XPLAN.DISPLAY to get a proper output, and use the \ tag before and after when posting here to format it using fixed font. Use the "Quote" button in the message editor to see how I used the \ tag here.
Are above queries representing the actual queries used or did you omit some predicates etc. for simplicity?
By the way, VARCHAR2(38) and ...ID as name, are these columns storing number values?

Hi All,
I was performing the steps mentioned in Oracle Tutorial"http://www.oracle.com/webfolder/technetwork/tutorials/obe/fmw/bi/bi11115/biadmin11g_02/biadmin11g.htm#t10"-BI RPD creation.
After Using the AGO function data in the Time series metric(Month Ago Revenue) was null always. I updated the DB features in RPD physical layers by selecting support for time series functions.
After that report started to fail with below error. Please let me know if its a bug and any option to fix it.

But as it's working with the 11.1.1.6.2 BP1 version I don't understand why it's not working with 11.1.1.6.9.
Implicit fact column is not set on my repository, but I don't have any request with only dimensional column, so if my understanding is correct I don't need to use it. Also, the problem appears during the check of the repository not in answers.
thanks anyway
