Problem with query performance
Hi All,
While loading data if we run the report, will it make any difference in the query performance? I have a cube with 230 million records I am running the delta which has got another 230 million records. Now I am trying to run the queries on the cube, all those timed out.
But I have a DSO with the 480 million the same queries are running good on the DSO. But I wanted to run the reports on the cube not on DSO what can I do? Is the data load giving any problem in the query runtime??
Pleas advise me what to do?
Regards
Kiran

View with columns based on function - problem with query
Hi,
I'm using Oracle 9i;
I've created a view which has columns based on a table columns (multiple columns from 1 table) and funtion (multiple columns based on 1 function).
The function takes ID as the first argument and name of the column to determine which value to return as the second one.
Here is a sample of such function (simplified):
FUNCTION my_function
(in_id IN NUMBER, in_col_name IN VARCHAR2)
RETURN VARCHAR2
IS
c_name VARCHAR2(100);
c_last_name VARCHAR2(100);
BEGIN
SELECT T.NAME, T.LAST_NAME
INTO c_name, c_last_name
FROM TABLE_1 T, TABLE_2 Z
WHERE T.PK = Z.FK
AND Z.ID = in_id;
IF in_col_name = 'NAME' THEN
RETURN c_name;
ELSIF in_col_name = 'LAST_NAME' THEN
RETURN c_last_name;
END IF;
END;
For simplicty I've restricted the number of columns.
CREATE OR REPLACE VIEW my_view
(ID, NAME, LAST_NAME)
AS
SELECT
T.ID ID
,CAST(my_function(T.ID,'NAME') AS VARCHAR2(100)) NAME
,CAST(my_function(T.ID,'LAST_NAME') AS VARCHAR2(100)) LAST_NAME
FROM TABLE T;
There is no problem with query:
SELECT * FROM my_view;
The problem arises when I query the view (regardles of '=' or 'LIKE'):
SELECT * FROM my_view
WHERE name LIKE '%some_part_of_name%'
The query returns rows for same names, for same it doesn't. If I put '=' and the whole name the query returns nothing, but when I put 'LIKE' and the first letter it returns rows in some cases.
I've tried to debug this situation and I've discovered that the function recives ID not in the proper order and not the same amount of times - in explicit:
for each ID in (1, 2, 3, 4, 5, 6, ... , 100) the function should be called twice for each ID and in the same order, but it does not.
I get 1, 1, 2, 3, 3, 6, 20, 20 and so on.
Help needed.
Greetings.The problem is more complicated than the solutions provided here.
The reason why I'm using the function is this:
the original view was constructed using multiple union all selects and the speed was terrible. I've created the index on the base table to obtain a proper sort. For retriving all records at once the view works perfectly, but if one wants to query by columns based on function the results are suprisng - sometimes there are, some times there are none, or if you serch with "like" and only a part of string there are results, but with "=" there are no results.
Here are real DDLs:

Updated Illustrator CC to CC 2014, having problems with CC performance. Slow and does not quit. What can be causing the issue?
Hello, please checkout my post concerning lagging issues.
I've also provided a link to a video I've recorded showing the Illustrator behavior on my iMac 27"

I have problems with the performance of the adjustment brush. It is a very bad workflow.
Had you specified you're on Windows, I wouldn't even have replied. I don't do windows.
Yes, it has been a waste of time for both you and me.
You don't even know how to ask a question properly and you want me to read the FAQs? Hah!
No one will take your word for "ACR latest version", and "PS CC latest VersionVersion [sic]", as many users believe they are fully updated when they are not. Exact version numbers are needed.
8 GB is considered the realistic minimum to run Photoshop CC, but it's far from optimal—on any platform. There are other factors that can be at play and which you don't specify, such as the space available on each of your hard drives, whether you have a physically separate, dedicated hard drive for Photoshop's scratch drive, what video card you have and how much VRAM does it have, what your graphics settings are in Photoshop's Preferences > Performance, etc.
That's why I had indicated a link for you to read:

Performance problem with query on bkpf table
hi good morning all ,
i ahave a performance problem with a below query on bkpf table .
SELECT bukrs
belnr
gjahr
FROM bkpf
INTO TABLE ist_bkpf_temp
WHERE budat IN s_budat.
is ther any possibility to improve the performanece by using index .
plz help me ,
thanks in advance ,
regards ,
srinivashi,
if u can add bukrs as input field or if u have bukrs as part of any other internal table to filter out the data u can use:
for ex:
SELECT bukrs
belnr
gjahr
FROM bkpf
INTO TABLE ist_bkpf_temp
WHERE budat IN s_budat
and bukrs in s_bukrs.
or
SELECT bukrs
belnr
gjahr
FROM bkpf
INTO TABLE ist_bkpf_temp
for all entries in itab
WHERE budat IN s_budat
and bukrs = itab-bukrs.
Just see , if it is possible to do any one of the above?? It has to be verified with ur requirement. -
Performance Problem with Query load
Hello,
after the upgrade to SPS 23, we have some problems with loading a Query. Before the Upgrade, the Query runs 1-3 minutes, and now more then 40 minutes.
Does anyone have an idea?
Regards
MarcoHi,
Suggest executing the Query in RSRT transaction by choosing the option ' Execute+Debugger' to further analyze where exactly the query is taking time.
Make sure choosing the appropriate 'Query Display' (List/BEx Analyzer/ HTML) option before Executing the query in the Debugger mode since the display option also effect the query run time.
Hope this info helps!

Hello Experts,
I'm tryng to develop my first application for EP (v7 SP12) with NWDS (without NWDI).
This application has to read and write data in the EP DB (oracle v10).
I'm using:
<u>a Dictionary Project</u> (define the DB Tables)
<u>a Java Project</u> (define class as DAO, DBManager etc)
<u>a Library Project</u>
<u>an EJB Project</u>
<u>an EAR Project</u>
With these projects I can deploy a <u>webService</u> in my EP server.
BUT I have some problem with a query that I'm tryng to sent to my DB through a DAO Class called by my WebService.
The query is simple and correct but it does not work...
This is the error message returned (the query id in bold)

The variable '?' is the today date, the difference <b>"(?-GIORNO)"</b> is an int..
Moreover in my DAO class the query is <b>"SELECT NOMESETTORE, MIN(? - GIORNO) AS GIORNI FROM SRS_DATEINFORTUNI WHERE NOMEDITTA = ? AND NOMEAREA= ? GROUP BY NOMESETTORE ORDER BY NOMESETTORE</b>", instead in the error message is reported <b>MIN(? - "GIORNO")</b>...
We have tryed also with alternative query, for example we used <b>"MIN(SYSDATA - GIORNO)"</b> but <b>SYSDATA</b> was interpreted as column name and not found....
Any help???
Best RegardsHi, I found something about the Host Variable (http://help.sap.com/saphelp_nw70/helpdata/en/ed/dbf8b7823b084f80a6eb7ad43bdbb9/content.htm), there explain that if you want to use an host variable you have to put ':' as prefix..
My problem is that <u>I need to extract the minimum of the subtraction between two dates:</u>
Query <b>MIN(? - GIORNO)</b> --> <i>Error: the arithmetic expression >>? - "GIORNO"<< contains a host variable (parameter marker)</i>
So I tried to use the ':' as indicated in the manual..
<b>MIN:(? - GIORNO)</b> --> - <i>SQL syntax error: the token ":" was not expected here
- expecting LPAREN, found ':'</i>
<b>MIN(:(? - GIORNO))</b> --> <i>- 1:25 - Open SQL syntax error: :PARAMETER not allowed
- 1:26 - SQL syntax error: the token "(" was not expected here
- 1:26 - expecting ID, found '('</i>
Then I tried to avoid the MIN() function and I tried to do just the subtraction:
<b>? - GIORNO</b> --><i> - 1:21 - the arithmetic expression >>? - "GIORNO"<< contains a host variable (parameter marker)</i>
<b>:(? - GIORNO)</b> --> <i>- 1:21 - Open SQL syntax error: :PARAMETER not allowed
- 1:22 - SQL syntax error: the token "(" was not expected here
- 1:22 - expecting ID, found '('</i>
<b>'2007-09-24' - GIORNO</b> --> <i>- 1:34 - SQL syntax error: first argument of operator "-" must be a number, date/time or interval
- 1:43 - SQL syntax error: arguments of operator "-" do not have correct types
- 1:43 - SQL syntax error: derived columns in SELECT list with AS must be values</i>
<b>GIORNO - GIORNO</b> --> <i>- 1:21 - the group by list and the select list are inconsistent: the column >>"GIORNO"<< is neither grouped nor aggregated
- 1:30 - the group by list and the select list are inconsistent: the column >>"GIORNO"<< is neither grouped nor aggregated</i>
Why these parts of query are not accepted???
I don't understand why... I hope you can help me.

Problems with Query Panel with Table
Hi. I'm having a problems with this component in runtime. I'm using JDev 11.1.1.1 with ADFBC.
The query uses three optional parameters. When i put a value for the first and leave other blank and execute query, following error is produced:

ThanksFrank,
I am also getting the same error. The version I am using is 11g Release 1(11.1.1.2.0)
Here is what I did:
1. created a view criteria on a view object
2. all are optional
3. Dragged the view criteria as a query component (query panel with query table) on to the design layout
and the error when I clicked the Search button is:

i have problems with a query, i need that have the follows fields.
SELECT T0.[DocNum] AS #Doc, T0.[NumAtCard] AS Referencia, T0.[docDate] AS Fecha, T0.[LicTradNum] AS RFC, T0.[CardName] AS 'Nombre del Cliente', T0.[DocTotalFC] AS TotME, T0.[DocRate] AS 'TC Fact', T0.[DocTotal] AS TotMS, T0.[VatSumFC] AS 'IVA ME', T0.[VatSum] FROM [dbo].[OINV] T0
But i need to know if this invoices have a PR, RF, RC,etc.
I saw that ORIN(RIN1) is for -> RC, OINV(INV9) -> RF, ORCT -> PR but i dont know how make a correctly INNER JOIN. When the invoice have a PR giveme Num of PR, if the invoice have a RC giveme the number of document destination.
So, how can i join these tables for get that information.
Thank you for you help.SELECT * FROM ORDR T0
INNER JOIN RDR1 T1 ON T0.DocEntry = T1.DocEntry
This is a basic inner join created from the SAP Query Generator
Template would be
Select <field names> FROM <base table name>
Inner join <table you want to join> on <<condition you want to two tables to joins>>
or
Simply you can write it
SELECT * FROM ORDR T0, RDR1 T1 WHERE T0.DocEntry = T1.DocEntry
it will do the same thing and you can simply join more tables.
Hope this will help...

ALERT PROBLEM WITH QUERY OUTPUT
I have a few queries that were originally created using the B1 Query Wizard, that I then attached to Alerts. Unfortunately when the Alert runs, the query output is different either in layout or records returned (usually less) when compared to running the query directly. Is this a glitch in B1 as some folks have told me or is there a problem with queries created by the Query Wizard?
Hi Frank,
This is a limitation.
The note 874145 is written about it. It also offers some workarounds.
I would think that you can also create a 'Select count(*)' query that would also run as an alert that would tell the user how many records are affected. I did not test this, just an idea.
Hope it helps,

Hi,
I have a multi provider with 2 cubes & 3 ODS & 1 info object.
On top of this MP queries are built. All the queries are in 3.5
It takes more then 30 min to execute each query.
Now we are planning to replace all 3.5 queries in 7.
We will build cube on top of 3 ODS. New MP will have 3 cubes & 1 Info object.
My issue is, the other 2 cubes are too large. We have around 4 million records in each.
And i need only few fields from these cubes.
Is there any way I can have less load on MP?
What would be the best approach to improve query performance?
Thanks,
GowriHello Gowri,
I think you should take the help of Aggregates.
You may create aggregates on the 2 large cube, using the characteristics
that you are using in the Query.
Since that cubes are having large amount of data, the use of aggregates will consideraly
reduce the Data manager time i.e. time spent by the query in retriving data from info-provider.
for more details on aggregates please refer the following link:
http://help.sap.com/saphelp_nw04/helpdata/en/7d/eb683cc5e8ca68e10000000a114084/content.htm
Thanx and regards

Syntax problem with BDC perform
Dear Friends,
small problem in BDC Perform syntax but I am not getting how to do this..
I have writen the code like this in my BDC byt its throughing the error...Here I want to do the validation on each and every field. I mean If that field values are empty i don't want to change the SAP field value.
my code is like this.
PERFORM dynpro USING:
'X' 'SAPLMGMM' '0080'.
IF NOT p_int_matl-werks IS INITIAL.
' ' 'RMMG1-WERKS' p_int_matl-werks.
ENDIF.
IF NOT p_int_matl-werks IS INITIAL.
' ' 'RMMG1-LGORT' p_int_matl-lgort.
ENDIF.
' ' 'BDC_OKCODE' '/00'.
pls give me exact code how to do this...
Thanks
SridharHi sridher,
1. this kind of syntax ie. IF will give error.
2. If ur requirement is : blank value should not be put in bdc,
3. then one way is to change / write the logic
inside the form itself.
4. ie. inside the routine/form DYNPRO.
5. So, it will be then general for all performs.
regards,

Performance problem with query
Hi,
I have a query.
SELECT
CDW_DIM_DATUM_VW.DATUM
,sum(CDW_FT031_DISCO_VW.RATE_CHARGEABLE_DURATION/60)
FROM
CDW_FT031_DISCO_VW,
CDW_DIM_DATUM_VW
WHERE CDW_DIM_DATUM_VW.DATUM >= to_date('20110901','yyyymmdd')
AND CDW_DIM_DATUM_VW.DATUM < to_date('20110911','yyyymmdd')
AND CDW_DIM_DATUM_VW.DATUM_KEY=CDW_FT031_DISCO_VW.DATUM_KEY
GROUP BY
CDW_DIM_DATUM_VW.DATUM
This query takes 2hrs on production normally which has to take 2 mts.
On checking Explain plan i understood that it is doing full table scan on cdw_ft031 which is the table used in view(cdw_ft031_disco_vw) which has got 30 lakh records.
I analyzed tables and indexes. I rebuilt all indexes . I used hints also but even then it is doing full table scan.
There are indexes created on columns refered in where clause.
Kindly help me.As the source are VIEWS your code is even not showing the full code. (Beside not showing the tables, indexes etc)
which has got 30 lakh recordsfrom wikipedia:
lakh is a unit in the Indian numbering system equal to one hundred thousandSo if you what that we do understand what your problem is, give us as much information as you have in a language the world understands.
I guess "CDW_DIM_DATUM_VW" is a "time dimension" so it has 1 row per date? Why is it a view?
Then the only join is to CDW_FT031_DISCO_VW where "FT" stands for "Fact"? (Why is it a views?)
What you want is that it picks the index (which it has on DATUM_KEY??) instead of a full table scan?
Is cdw_ft031 parititioned? (You often partition a fact via date, and you see "full table scan" which stand for "full partition scan".
So your fact has 3 Million rows? And the query takes 2 hours? My laptop would do that in less without any index.... there is sometime completely wrong.
I discourage the join of views, but based on what you gave us, hard to give advices. -
Dear all,
I have this query which returns me the quantity received through inventory transfer window against quantity sent out through the same window. There can be multiple receipts against one dispatch (Jobwork) and the receipts are linked through a udf which carries the docnum of the document through which the material went out for jobwork. Now my problem is that the query throws me the balance quantity per row i.e suppose material sent out 10 nos and received 5 times 2 nos. The query shows me 8 as balance in all the five rows whereas I want the query to show me 6 in the 2nd row, 4 in 3rd row and so on. I hope I have made myself clear: Kindly help me with this query.

Problems with Photoshop performance and data transfer speed on iMac
Two months ago, I started noticing slow performances using Photoshop (above all using clone stamp tool) on my 27" iMac (late 2012). I did the AHT and I found that 8GB of 32GB RAM were broken.
I removed them but the problem didn't disappered, I also noticed that data transfer speed (both copy and paste from/to internal HD and from CF card/external HD) was really slow.
I tried many solutions suggested by Apple support, none of them worked out. At the end, I tried uninstalling and re-installing Photoshop: no more problems!!!
10 days ago, I received a new 8GB RAM module and so I installed it back... suddenly, the problem came back, I tried re-installing again Photoshop but the problem, this time, still persist!
Does anyone had the same experience? All other CC programs work well (LR, AE, Premiere...)yes, it does!
what seems to be very strange to me is how data trasnfer speed could be affected!
(just to say, I've already tried reset of SMC and PRAM, I've tried with different accounts and I've also re-installed the OS, next step would be formatting the disk and installing the OS from zero)
