Kind regards,
NikOk, so I am going to be a little bit kinder then your first reply, but not much.
From what can tell you are doing medical management and are trying to select by AGE/GENDER CELLS and this is common when trying to deal with RBRVS.
This is by far some of the worst sql I have ever seen, sorry but it just is.
So please report this either as a new post or as a reply and:
1. At least post the table definitions and if you can some sample data.
2. Get rid of almost all the case selectors.
3. Describe the output you need.
As it is this is unreadable.
After that we can talk more.

Is there any way I can display same user_ID 88 on the null USER_ID (Joined one)
my result is

What we were asking you is to post data we can work with rightaway, so CREATE TABLE statement, and INSERT INTO statement. So: not output, but statements...
Since I'm in a good mood (we're in the semi finals ;) ), here's an example of how you should post your data:
create table a1 as
select 1 quest_code, 'Fibrostenotic' quest_desc from dual union
select 2, 'Inflammatory' from dual union
select 3, 'Int Penetrating/Perforating' from dual union
select 4, 'Perianal Perforating Disease' from dual union
select 5, 'Uc Like' from dual union
select 6, 'Flare Of Disease' from dual union
select 7, 'Immunosuppressive Tx' from dual union
select 8, 'Iv Therapy' from dual union
select 9, 'Stool Consistency' from dual union
select 10, 'Urgency' from dual union
select 11, 'Stool Frequency' from dual union
select 12, 'Bleeding' from dual union
select 13, 'Adb Pain' from dual union
select 14, 'Fever/Chills' from dual union
select 15, 'Fistula' from dual union
select 16, 'Obstructive Sx' from dual union
select 17, 'Extraintestinal Sx' from dual union
select 18, 'Steroid Dependent' from dual union
select 19, 'Sibo' from dual union
select 20, 'Osteoporosis' from dual union
select 21, 'Osteopenia' from dual union
select 22, 'Growth' from dual union
select 23, 'Other' from dual;
create table a2 as
select 1 quest_code, 'U' quest_response, 88 user_id from dual union
select 2, 'U', 88 from dual union
select 3, 'U', 88 from dual union
select 4, 'U', 88 from dual union
select 5, 'U', 88 from dual;
create table a3 as
select 'testuserb' user_name, 88 user_id from dual;Posted like that, we can copy+paste and try to help you rightaway instead of waisting time formatting, putting quotes right etc. etc.
Also use the {noformat}{noformat} tag when you post an example.
That way it will stay formatted and indented.
So, when you type: {noformat}select *
from dual;{noformat}
it will appear as: select *
from dual;when you post it.
Finally, perhaps you could try something like this:SQL> select a1.quest_desc
2 , a2.quest_response
3 , case
4 when (select a3.user_id
5 from a3
6 where a3.user_id = a2.user_id) is not null
7 then (select a3.user_id
8 from a3
9 where a3.user_id = a2.user_id)
10 else (select a3.user_id
11 from a3
12 where a3.user_name = 'testuserb')
13 end user_id
14 from a1
15 , a2
16 where a1.quest_code = a2.quest_code(+);
QUEST_DESC Q USER_ID

bdl_voy,
bdl_location,
bdl_type,
user,
sysdate,
user,
sysdate,
'0',
sysdate,
sysdate
from bl_details;Also:
To post formatted code, put the {noformat} {noformat}- tag before and after your examples.
When you post:
{noformat} select *
from dual;
{noformat}
it will appear as: select *
from dual;

Help with rewriting the query for faster execution.
Hello Everybody,
We are on Version
Oracle Database 10g Enterprise Edition Release 10.2.0.5.0 - 64bi
I am trying to get data from tab1 where col8 is equal to ' ' at the same time If we 2 or 3 records matched on col1 and col2 with different dates(col3) i am only interested in getting one record with the least date....
Here is the sample data...
Col1 col2 col3 COL4 COl5 Col6 COL7 COL8 COL9
12 1 17-JAN-13 1 5 7 9 1233333 25

Below query works and we have close to billion rows in a table but the where clause would filter out to 100 mill records.
and i am trying to see if there is an effecient way of writing this....we have an index on COL3.
Select col1,col2,col3,col4,col5,col6,col7,col8,col9 from(Selct of.,row_number() over (partition by col1,col2 order by col3 asc) as rnk
from tabl of where of.col8 = '1233333') where rnk = 1*
From the above query i get the below explain plan

Hi Gurus,
I m woking on performance tuning at the moment and wants some tips
regarding the Query performance tuning,if anyone can helpme in that
rfrence.
the thing is that i have got an idea about the system and now the
issues r with DB space, Abap Dumps, problem in free space in table
space, no number range buffering,cubes r using too many aggrigates,
large IC,Large ODS, and many others.
So my questionis that is anyone can tell me that how to resolve the
issues with the Large master data tables,and large ODS,and one more
importnat issue is KPI´s exceding there refrence valuses so any idea
how to deal with them.
waiting for the valuable responces.
thanks In advance

AmitHi Amit
For Query performance issue u can go for :-
Aggregates : They will help u a lot to make ur query faster becuase query doesnt hits ur cube it hits the aggregates which has very less number of records in comp to ur cube
secondly i wud suggest u is use CKF in place of formulaes if any in the query
other thing is avoid upto the extent possible the use fo nav attr . if u want to use them use it upto the minimal level reason i am saying so is during the query exec whn ever there is nav attr it provides unncessary join to ur MD and thus dec query perfo
be specifc to rows and columns if u r not sure of a kf or a char then better put it in a free char.
use filters if possible
if u follow these m sure ur query perfo will inc
Assign points if applicable
Thanks

Query Performance Issues on a cube sized 64GB.
Hi,
We have a non-time based cube whose size is 64 GB . Effectively, I can't use time dimension for partitioning. The transaction table has ~ 850 million records. We have 20+ dimensions among which 2 of the dimensions have 50 million records.
I have equally distributed the fact table records among 60 partitions. Each partition size is around 900 MB.
The processing of the cube is not an issue as it completes in 3.5 hours. The issue is with the query performance of the cube.
When an MDX query is submitted, unfortunately, in majority of the cases the storage engine has to scan all the partitions (as our cube is not time dependent and we can't find a suitable dimension that will fit the bill to partition measure group based
on it.)
I'm aware of the cache warming and usage based aggregation(UBO) techniques.
However, the cube is available for users to perform adhoc queries and hence the benefits of cache warming and UBO may cease to contribute to the performance gain as there is a high probability that each user may look at the data from different perspectives
(especially when we have 20 + dimensions) as day(s) progress.
Also, we have 15 + average calculations (calculated measures) in the cube. So, the storage engine sends all the granular data that the formula engine might have requested (could be millions of rows) and then perform the average calculation.
A look at the profiler suggested that considerable amount of time has been spent by storage engine to gather the records (from 60 partitions).
FYI - Our server has RAM 32 GB and 8 cores and it is exclusive to Analysis Services.
I would appreciate comments from anyone who has worked on a large cube that is not time dependent and the steps they took to improve the adhoc query performance for the users.
Thanks
CoolPHello CoolP,
Here is a good articles regarding how to tuning query performance in SSAS, please see:
Analysis Services Query Performance Top 10 Best Practices:
http://technet.microsoft.com/en-us/library/cc966527.aspx
Hope you can find some helpful clues to tuning your SSAS Server query performance. Moreover, there are two ways to improve the query response time for an increasing number of end-users:
Adding more power to the existing server (scale up)
Distributing the load among several small servers (scale out)

Either the statistics are not up to date, the data values are skewed or you have some optimizer parameter set to none default to force index access.
Please post explain plan and optimizer* parameter settings. -
Having more LTSs in logical dimension table hit the query performance?
Hi,
We have a logical table having around 19 LTSs. Having more LTSs in logical dimension table hit the query performance?
Thanks,
AnileshHi Anilesh,
Its kind of both YES and NO. Here is why...
NO:
LTS are supposed to give BI Server an optimistic and logical way to retrieve the data. So, having more Optimistic LTS might help the BI Server with some good options tailored to a variety of analysis requests.
YES:
Many times, we have to bring in multiple physical tables as a part of single LTS (Mostly when the physical model is a snowflake) which might cause performance issues. Say there is a LTS with two tables "A" and "B", but for a ad-hoc analysis just on columns in "A", the query would still include the join with table "B" if this LTS is being used. We might want to avoid this kind of situations with multiple LTS each for a table and one for both of them.
Hope this helps.
Thank you,
Dhar -

hi..
My SP is as above..
I connected this SP to dataset in SSRS report..as per my logic..Portfolio contains many Programs and Program contains many Projects.
When i selected the ALL value for parameters Program and Project..i'm unable to get output.
but when i select values for all 3 parameters i'm getting output. i took default values for paramters also.
so i commented the where condition in SP as shown above
--------where TSK.ProjectID=@Project-------------
now i'm getting output when selecting ALL value for parameters.
but here the issue is performance..it takes 10sec to retrieve for single project when i'm executing the sp.
how can i create index on temp table in this sp and how can i improve the query performance..
please help.
thanks in advance..

Need help in refining the query
Hello Experts,
Need your help in refining the query further more.
table structure
Mskey Col A Col B

1 empno [20151201-99991231]232544

2 salutation [20141127-99991231]Mrs
2 salutation [20151127-99991231]Mr
My requirement is to find the list of overlapping records based on the dates
user details may be varying from time to time as new data would be pushed through HR systems to identity store via an interface.
The job is getting failed whenever there is any overlapping with dates. So we proactively decided to schedule a job in this regards which runs weekly and would let us know for which and all the users there is overlapping dates are there, so that we can send the list to HR team for pushing new data.
Overlapping Issue Example:
The users employee id for an year it is 1234 and later he moved to another department and his employee id got changed and it became 2345 remaining all details are same. So the HR systems send the data for this user as empno - [20141127-20151128]1234 and empno - [20151201-99991231]232544
it means from 20141127 to 20151128 his employee no is 1234 and from 20151201 to 99991231 his employee would be 2345.
This is a correct case and the tool would accept this data.
the below cases are invald
Case 1: 1 salutation [20141127-99991231]Mrs 1 salutation [20151127-99991231]Mr
Case 2: 2 salutation [20141127-99991231]Mrs 2 salutation [20141127-99991231]Mr
So we wanted to find these overlapping records from tables.
My Query:
I am able to successfully write query for the case 2 type but unable to write for case1.
select id,colA
count(left(ColB,CHARINDEX(']',ColB))) as 'Count'
from tblA with (nolock)
where id in (Select distinct id from tblb with (nolock))

Building a new Cube Vs Restricted Key figure in Query - Performance issue
Hi,
I have a requirement to create a OPEX restricted key figure in Query. The problem is that the key figure should be restricted to about 30 GL Accounts and almost 300 Cost centers.
I do not know if this might cause performance issue in the query. At the moment, I am thinking of creating a new OPEX cube and load only those 30 GL Accounts, 300 cost centers and Amount. and include OPEX in multiprovider in order to get OPEX
amount in the report.
whats the best solution - creating OPEX restricted key figure or OPEX cube ?
thanks,
BhatI think you should go for cube as all the restrcited key figure are calculated at OLAP runtime so it will definitely affect the query performance.There are a lot of costcenter for which you have to restrict it so definitely during the runtime of query it will take a lot of time to fetch tha data from infoprovider.Its better that you create a cube with the restrictions and include it in MP.It will definitely save a lot of time during query execution

Rewrite the query with out joins and group by
Hi,
This was an interview question.
Table Names: bookshelf_checkout
bookshelf
And the join condition between these two tables is title
We need to rewrite below query without using join condition and group by clause ?
SELECT b.title,max(bc.returned_date - bc.checkout_date) "Most Days Out"
FROM bookshelf_checkout bc,bookshelf b
WHERE bc.title(+)=b.title
GROUP BY b.title;When I was in college, I read that most of the SELECT statements can be replaced by basic SQL operations (SET OPERATORS). Now I am trying to rewrite the query with SET operators but not able to get the exact result.
Kindly help me on this.
Thanks,
