0BWTC_C02 - Viewing number of query executions and refreshes

Hi,
I having been testing some queries I created for infocube 0BWTC_C02. Is there any way to limit the key figure 0TCTNAVCTR to only show navigations that were query refreshes (e.g. ignoring navigations such as removing/adding a drilldown, results row, ect.)? Do any of the available characteristics show what type of navigation was being performed, so that I could restrict the query to only look at certain types of navigations?
Thanks,
Andy

Hi Pcrao,
I am using the BW statistics infocube 0BWTC_C02.
But as far as I see, the key figure 0TCTNAVCTR( number of navigation steps)now only includes query execution, but also includes all other navigation steps like drill down etc.
Can we do some restriction on navigation type etc to find just the number times query execution takes place?
Thanks,
James

Bitmap indexes have effect on query execution and equation of values.

Hi,
I have a Fact table and 17 dimension tables linked to it. On each foreign-key in the Fact-Table I have created a BITMAP Index. After that I Analyzed the fact table and made sure that the referential constraints were valid.
Everything seem to be OK until I ran into a difference in totals when using the next 2 queries that should both result into the same total amount.
Query 1:
Below query is resulting in a wrong total amount and seems to be cartesian.
SELECT    SUM(F.DOLLARS)
FROM       SALES_FACTS         F
,               DIM_TIME                A
,               DIM_CUSTOMER      B
,               DIM_SALESAGENT C
,               DIM_SALESTYPE     D
,               DIM_GEOGRAFIC     E
WHERE    F.TIME_ID     =     A.TIME_ID
AND         F.CUST_ID     =    B.CUST_ID
AND         F.SA_ID         =    C.SA_ID
AND         F.ST_ID          =   D.ST_ID
AND         F.GEO_ID       =   E.GEO_ID
AND         A.YEAR          =   '2006'
AND         C.SALESNUM =   '3770'
AND D.ST_ID <> '4'
Query 2:
Qeury 2 is the same as query 1 exept the the type of sales (D.ST_ID) is now set with in a range of allowed values. This query gives the correct result.
SELECT    SUM(F.DOLLARS)
FROM       SALES_FACTS         F
,               DIM_TIME                A
,               DIM_CUSTOMER      B
,               DIM_SALESAGENT C
,               DIM_SALESTYPE     D
,               DIM_GEOGRAFIC     E
WHERE    F.TIME_ID     =     A.TIME_ID
AND         F.CUST_ID     =    B.CUST_ID
AND         F.SA_ID         =    C.SA_ID
AND         F.ST_ID          =   D.ST_ID
AND         F.GEO_ID       =   E.GEO_ID
AND         A.YEAR          =   '2006'
AND         C.SALESNUM =   '3770'
AND D.ST_ID in ('1','2','3','5') In my situation it seems that when I use the <> (not equal to) symbols in combination with the bitmap indexes, that the result of the sum becomes cartesian and thus incorrect.
Has anyone an idea why the calculation of the total amount is different in both queries?
Any help is very appreciated.
Regards, Ilona

Another strange effect is when I leave out the quotation around the not equal to 4 for the Sales_type id (ST_ID <> 4 in stead op ST_ID <> '4' ) then the totals is perfect.
Query 1 version without quotations around ST_ID:
SELECT    SUM(F.DOLLARS)
FROM       SALES_FACTS         F
,               DIM_TIME                A
,               DIM_CUSTOMER      B
,               DIM_SALESAGENT C
,               DIM_SALESTYPE     D
,               DIM_GEOGRAFIC     E
WHERE    F.TIME_ID     =     A.TIME_ID
AND         F.CUST_ID     =    B.CUST_ID
AND         F.SA_ID         =    C.SA_ID
AND         F.ST_ID          =   D.ST_ID
AND         F.GEO_ID       =   E.GEO_ID
AND         A.YEAR          =   '2006'
AND         C.SALESNUM =   '3770'
AND D.ST_ID <> 4 I still have no clue what causes this effect.

Number of query values and destination fields are not the same.

Hey can any one help me out with this. I have no idea where i'm going wrong.
String query_beg="insert into [insert$] values('"+rs1.getString("USERID")+"','"+rs1.getString("NAME")+"','"+beg_1+"','"+beg1_1+"','"+rs1.getTime("LOGINTIME")+"','"+rs1.getString("CLIENT_TIMEZONE")+"')";
int num = stmnt2.executeUpdate(query_beg);Thanks in advance!
Cheers

I think it�s missing some field in your values

Query Performace and Order by

Hello All -
I have a query which executes in 250msecs. The moment I throw an order by clause in it the query takes 25secs to execute.
The order by clause in on PK (just 1 column of type NUMBER)
Records Returned : 300K
Point to Note is I only need top 500 rows after the sorting is done.
Can you please suggest some ways to reduce the time of query execution and still have order by clause in it.
Thanks for your help.

Thanks for your help.Show us your query. Maybe we can find a way to make it faster. Also do you order ascending or descending and what is your oracle database version?
This won't help much probably.

Query execution Flow

Dear Experts,
I would like to know how does the query execution happens @ runtime.
Definitely its a SQL which been executed in backend.
I have one scenerio Like Cube is having Material As Characteristic (M1,M2,M3)
& Navigation Attribute Material group (MG) also some kef Figure Like Sales-Values.
So can you please let me know what will be the order of tables which will be
referred @ runtime when I execute the query.
Please Advice.
Regards,
Vivek

Hi,
Check in RSRT with execute+debug and select SQL display, you will find the information.
Check the below blogs for more info:

Finding number of working days during query execution

Hi ,
We have a requirement to calculate number of working days during query execution. In the cube we got "received date", this will be used as a variable in the query. Based on the received date value entered, query needs to display number of products received from past 1, 2,3,4 days (working days should include weekends or public holidays).
1day 2 days 3 days 4 days 5 days
10 12 20 15 20
to me it appears as I need to create virtual key figures.
Regards,
Ramz

Hi ramesh,
First try to create formula variables for start data and end date to calculate the no of working days.
Create a Variable ZSTDT --of type replacement path.
Type of Variable = Formula
Variable Name = ZSTDT
Characteristic = <info object>
For Intervals Use = Select From Value
Offset Start = 0000 Offset Length = 0000
Replacement var with : key
use the same steps to create one more formula variable to get end date.
Now create a formula to get the No of days.
once after getting no of days you can create buckets as per your need.
for more info check the below links

Materialized view - parameter and refresh

Hi,
We are creating a Materialized view that has 2 rows for a CCID, one for this year and one for previous year with balances in 12 buckets.
We have 2 questions:
1. Can a materialized view be created with a parameter? or it can only take hard coded values?
2. Can we refresh a part of materialized view, lets say we want to refresh the balances only for this year?
Thanks

We have 2 questions:
1. Can a materialized view be created with a parameter? or it can only take hard coded values? Typically, you want a materialized view to contain a complete set of aggregate data ... so, no, parameters don't really make sense (also, the results are pre-computed unlike a regular VIEW which is just a stored query. With a MV the data is actually computed on creation unless you defer it, and takes up physical storage).
>
2. Can we refresh a part of materialized view, lets say we want to refresh the balances only for this year?
You can (depending on your Oracle Version and complexity of your materialized view) create a materialized view that does fast refreshes. If for some reason it was pertinent for you to achieve what you've asked, you could make 2 MV's and then a view that does a UNION ALL of them (the MV's would not contain overlaps), then you would just refresh the 1 MV, seems odd to me to want to do this though.
Thanks

Oracle View that stores the Query execution time

Hi Gurus
i m using Oracle 10G in Unix. I wudiold like to know which Data dictionary view stores the execution of a query. If it is not stored then hw to find the query execution time other than (Set timing on) command. What is the use of elapsed time and what is the difference between execution time and elapsed time? How to calculate the execution time of a query.
THanks
Ram

If you have a specific query you're going to run in SQL*Plus, just do
a 'set timing on' before you execute the query.
If you've got application SQL coming in from all over the place, you can
identify specific SQL in V$SQL/ and look at ELAPSED_TIME/EXECUTIONS
to get an average elapsed time.
If you've got an application running SQL, and you need to know the
specific timing of a specific execution (as opposed to an average),
you can use DBMS_SUPPORT to set trace in the session that your
application is running in, and then use TkProf to process the resulting
trace file.

View query execution taking more time

hi all,
what would be the reason that my event view is still not getting executed for around 24 hours.
actually i created 2 event views one is like ora1 and another is like ora1_1 both are having the same data.
the first view ora1 executed by 14 hours.
but my second view still not get executed it is still running for last 30 hours.
very urgent.
plz tell me the reason for the delay
and if possible provide me a solution too
thanks in advance

Strange query plans, and so different results from a view.

In my database (11g), I have a currency exchange rate table, which contains all currencies and their exchange rate to USD. I need to have a number of different exchange rates - To GBP, EUR, etc...
To accomplish this I have created a view, which has one union statement of all the USD exchange rates, with the same data joined back on itself to give the exchange rates based on their exchange rate to USD - ie: SELECT b1.Date, b1.Currency AS FromCurrency, b2.Currency as ToCurrency, b1.Rate/b2.Rate as Exchange Rate FROM Rates b1, Rates b2 on b1.Date = b2.Date
This view works fine when I query it, and returns the data as I expect.
I have a second view that is joined to this view to give a return of the amount in each currency for reporting. This view seems to work correctly when I narrow down the search requirements and have a small set of data.
The issue I am having is when I query the second view and get it to return all the data. Instead of receiving 4 rows per transaction (I am only interested in 4 exchange rates for display) I typically receive up to 2 rows. The first record is for the conversion to USD, the second record is for the conversion to the supplied currency. The issue is that this exchange rate actually includes the aggregate for all 3 other requested currencies (not the USD).
So instead of getting something like:
Amt RC BC (Amt = Amount, RC = Reporting Currency. BC = Base Currency)
60 GBP GBP
80 EUR GBP
100 USD GBP
1000 ZAR GBP
60 GBP USD
80 EUR USD
100 USD USD
1000 ZAR USD
I get the following set of results:
1140 GBP GBP
100 USD GBP
100 USD USD
Has anyone come accross something similar or have any ideas on how I can resolve this?
Thanks
PS: I can get both sets of results from the same view depending on the filter criteria. Also if I convert the exchange rates into a table, it then returns the correct results as expected.

The idea is to seek help in solving the problem. I was hoping that perhaps someone had experienced the same thing - different results for "effectively" the same query:Well, that's the issue... without additional info, it's not clear what issue you were seeing.
SELECT * FROM view WHERE Date = '01 January, 2012'
verse
SELECT * FROM view WHERE Date > '31 December, 2011' ORDER BY DateNow it's a bit clearer. That second query is not "effectively" the same as the first query. If the date column is in DATE format, then you ought to have a to_date() around the date string to explicitly convert it into a date so you can do date-to-date comparisons correctly. Also, DATE datatype stores times as well as dates, so asking for data matching midnight of a specific date is different than asking for data greater than midnight of the previous day.
If the date string is a string, then ... well, the string "31 December 2011" is greater than the string "31 August 2013", despite it being an earlier date. This is why making sure you're using the right datatype for the job is important - a date is different to a string that just happens to contain a date.
DateID
I have no objection to using a Date but always struggle to understand what someone means when they tell me "06/07/2012" - granted if the day is above 12 or the same day and month I don't have a problem - but it still leaves 121 days a year that are confusing. sure, but just because you find outputting the display (or rather, someone else's output) confusing doesn't mean you still shouldn't use the correct datatype. Store things as a date, and you can then output it in whatever format you like. Try doing that with a string or a number.
Don't say it doesn't happen as I got a birthday card from a company in May this year when I have specifically entered my date of birth as being the 5 of a month (name drop down box on their website)!Just because someone else doesn't understand how to work with dates correctly doesn't mean you can't! It's not exactly rocket science, after all!*{;-)

After I run a query can I get it to return the number of files matched and each individual file name?

After I run a query can I get it to return the number of files matched and each individual file name? I am trying to do a data mining routine and this would be helpful.
BBANACKI

Hi bbanacki,
Please have a look at the following code:
Define your queries and then:
oAdvancedQuery.ReturnType=eSearchFile
oMyDataFinder.Results.MaxCount = iMaxNumberOfReturndElements
Call oMyDataFinder.Search(oAdvancedQuery)
Set oMyResults = oMyDataFinder.Results
If oMyResults.IsIncomplete Then
msgbox "The first " & str(oMyResults.Count) & " files found"
Else
msgbox str(oMyResults.Count) & " files found"
End If
for iLoop = 1 to oMyResults.Count
Cell.Text = oMyResults(iLoop).Properties("Name").Value
Cell.Text = oMyResults(iLoop).Properties("fullpath").Value
next

Help with query rewrite and materialized views

Hello everybody,
I'm currently learning how to use Oracle (10G Enterprise) and in particular, Materialized Views.
I seem to have a problem making the optimizer use a materialized view. I have already set the OPTIMIZER_MODE, QUERY_REWRITE_ENABLED and QUERY_REWRITE_INTEGRITY as needed.
I need to create a materialized view for the following query:
Q1:
SELECT PS_SUPPKEY, PS_PARTKEY, PS_SUPPCOST
FROM PARTSUPPLIER E, PART WHERE PS_PARTKEY=P_PARTKEY and (lower(P_COMMENT) LIKE ''_o_a\%'' or lower(P_COMMENT) LIKE ''_o_u\%'')
and PS_SUPPCOST =
(SELECT min( PS_SUPPCOST)
FROM PARTSUPPLIER I
WHERE E.PS_PARTKEY=I.PS_PARTKEY)'
I created it using the following code:
CREATE MATERIALIZED VIEW mv_q1
ENABLE QUERY REWRITE
AS SELECT PS_SUPPKEY, PS_PARTKEY, PS_SUPPCOST
FROM PARTSUPPLIER E JOIN PART ON (PS_PARTKEY=P_PARTKEY)
WHERE lower(P_COMMENT) LIKE '_o_a%' or lower(P_COMMENT) LIKE '_o_u%'
and PS_SUPPCOST=
(SELECT min( PS_SUPPCOST)
FROM PARTSUPPLIER I
WHERE E.PS_PARTKEY=I.PS_PARTKEY);
I have created the statistics using:
execute dbms_stats.gather_table_stats('frandres',' mv_q1');
execute dbms_stats.gather_table_stats('frandres','PARTSUPPLIER');
execute dbms_stats.gather_table_stats('frandres','PART');
Both partsupplier and part are tables and not views.
When executing Q1, the plan does not use the materialized view. Furthermore, when using explain rewrite:
DECLARE
qrytxt VARCHAR2(3000) := 'SELECT PS_SUPPKEY, PS_PARTKEY, PS_SUPPCOST
FROM PARTSUPPLIER E, PART WHERE PS_PARTKEY=P_PARTKEY and (lower(P_COMMENT) LIKE ''_o_a\%'' or lower(P_COMMENT) LIKE ''_o_u\%'')
and PS_SUPPCOST =
(SELECT min( PS_SUPPCOST)
FROM PARTSUPPLIER I
WHERE E.PS_PARTKEY=I.PS_PARTKEY)';
BEGIN
dbms_mview.EXPLAIN_REWRITE
(qrytxt,'MV_Q1','MV_Q1');
END;
I get the following message:
MESSAGE
QSM-01150: query did not rewrite
QSM-01263: query rewrite not possible when query references a dictionary table o
r view
QSM-01219: no suitable materialized view found to rewrite this query
What I can't understand is why it says I am referencing the dictionary or a view?
If I remove the (lower(P_COMMENT) LIKE ''_o_a\%'' or lower(P_COMMENT) LIKE ''_o_u\%'') condition to the query (using the same materialized view), I get the following message from EXPLAIN_REWRITE:
MESSAGE
QSM-01150: query did not rewrite
QSM-01219: no suitable materialized view found to rewrite this query
Which is reasonable.
I don't know if the like condition is messing up my materialized view. Can anyone please help?
Thanks a lot in advance.

Bingo!
The 10.2.0.3 patch set is supposed to fix this ( [List of bugs fixed (MVs)|http://www.dbatools.net/doc/bug10203.html#MVIEW] )
In particular:
5052568 Query rewrite does not work for SQL with LIKE clause.
Thank you very much for your message!
The downside is that I'm only using Oracle for educational purposes and consequently have no Metalink id, so I can't install the patch. Thanks a lot though!

Query Execution/Elapsed Time and Oracle Data Blocks

Hi,
I have created 3 tables with one column only. As an example Table 1 below:
SQL> create table T1 ( x char(2000));
So 3 tables are created in this way i.e. T1,T2 and T3.
T1 = in the default database tablespace of 8k (11g v11.1.0.6.0 - Production) (O.S=Windows).
T2 = I created in a Tablespace with Blocksize 16k.
T3 = I created in a Tablespace with Blocksize 4k. In the same Instance.
Each table has approx. 500 rows (So, table sizes are same in all the cases to test Query execution time ). As these 3 tables are created under different data block sizes so the ALLOCATED no. of data blocks are different in all cases.
T1 = 8k = 256 Blocks = 00:00:04.76 (query execution time/elapsed time)
T2 = 16k=121 Blocks = 00:00:04.64
T3 = 4k = 490 Blocks = 00:00:04.91
Table Access is FULL i.e. I have used select * from table_name; in all 3 cases. No Index nothing.
My Question is why query execution time is nearly the same in all 3 cases because Oracle has to read all the data blocks in each case to fetch the records and there is a much difference in the allocated no. of blocks ???
In 4k block size example, Oracle has to read just 121 blocks and it's taking nearly the same time as it's taking to read 490 blocks???
This is just 1 example of different data blocks. I have around 40 tables in each block size tablespace and the result are nearly the same. It's very strange for me because there is a much difference in the no. of allocated blocks but execution time is almost the same, only difference in milliseconds.
I'll highly appreciate the expert opinions.
Bundle of thanks in advance.
Best Regards,

Hi Chris,
No I'm not using separate databases, it's 8k database with non-standard blocksizes of 16k and 4k.
Actually I wanted to test the Elapsed time of these 3 tables, so for that I tried to create the same size
tables.
And how I equalize these is like I have created one column table with char(2000).
555 MB is the figure I wanted to use for these 3 tables ( no special figure, just to make it bigger than the
RAM used for my db at the db startup to be sure of not retrieving the records from cache).
so row size with overhead is 2006 * 290,000 rows = 581740000(bytes) / 1024 = 568105KB / 1024 = 555MB.
Through this math calculation I thought It will be the total table size. So I Created the same no. of rows in 3 blocksizes.
If it's wrong then what a mes because I was calculating tables sizes in the same way from the last few months.
Can you please explain a little how you found out the tables sizes in different block sizes.Though I understood how you
calculated size in MB from these 3 block sizes
T8K =97177 BLOCKS=759MB *( 97177*8 = 777416KB / 1024 = 759MB )*
T16K=41639 BLOCKS=650MB
BT4K=293656 BLOCKS=1147MB
For me it's new to calculate the size of a table. Can you please tell me then how many rows I can create in each of
these 3 tables to make them equal in MB to test for elapsed time.
Then I'll again run my test and put the results here. Because If I've wrongly calculated table sizes then there is no need to talk about elapsed time. First I must equalize the table sizes properly.
SQL> select sum(bytes)/1024/1024 "Size in MB" from dba_segments> 2 where segment_name = 'T16K';
Size in MB
655
Is above SQL is correct to calculate the size or is it the correct alternative way to your method of calculating the size??
I created the same table again with everything same and the result is :
SQL> select num_rows,blocks from user_tables where table_name = 'T16K';NUM_ROWS BLOCKS
290000 41703
64 more blocks are allocated this time so may be that's y it's showing total size of 655 instead of 650.
Thanks alot for your help.
Best Regards,
KAm

How to Create a View of a Query and assign it into my web template?

Hi All,
I need to create 3 views for my query and show that on my web template. I have never done this before. Can you please let me know step-by step procedure to create views for a query and how to show it on my WAD report?
Thanks,
Satyam

Hi Satyam,
Include the Dropdown Box web item in your web template. In the Web Item Parameters tab, select the Data Binding type as Query View Selection. Assign the Dataprovider from Selection of Query Views button below the Data Binding Type. You also have the option to Display Specific list of Query Views or all views based on that Query. For this you have to choose Selection of Query Views button. Here you can turn on Specific List of Query Views checkbox and select the Views depending on your requirement.
Regards,
Hari.

How query cost and execution time are releated ?

hi experts,
i am curious to know, how the query cost and execution time is related?
Query taking less time ,query cost is 65%, but query taking more time but query cost is 0%.
how to connect both and improve query performance.
Thanks

i think you are refering to cost (relative to the batch) execution 65%, where there are more that one statement, it may compare the cost of each statement with in the batch
i assume it mainly take subtree cost and IO stat as cost, but in some cases i may wrong when there is multi line function and many other facter influence the cost, and i would say it depends on the query
cost is unit-less
The reason these costs exist is because of the query optimization SQL Server does: it does cost-based optimization, which means that the optimizer formulates a lot of different ways to execute the query, assigns a cost to each of these alternatives, and
chooses the one with the least cost. The cost tagged on each alternative is heurestically calculated, and is supposed to roughly reflect the amount of processing and I/O this alternative is going to take.
