Can we suppress execution of a query so as to optionally execute queries in data modl

Can we suppress execution of a query so that we optionally execute queries?0
I have a combo box in Parameter Form. It has 3 options. I have 3 queries in Data Model.
I want to execute only one of these 3 queries based on user's selection from combo box.
I want that other 2 queries do NOT execute at all for that processing cycle. Next time user selects other option and an other query is executed and other 2 are NOT executed and so on.
Is it possible in Reports 6i in Client/server?
Pl. guide.
Tariq

Include:
AND :parameter = <this query's value> (e.g. 1 or "SALES" or whatever)
in each query's where clause. Because this is 2 constants (as far as the SQL interpreter is concerned) it will evaluate it first. If the parameter is set to a value not for this query then it will return no rows with minimal overhead.

How can I get the elapse time for execution of a Query for a session

Hi ,
How can I get the elapse time for execution of a Query for a session?
Example - I have a report based on the procedure ,when the user execute that it takes say 3 min. to return rows.
Is there any possible way to capture this session info. for this particular execution of query along with it's execution elapse time?
Thanks in advance.

Hi
You can use the dbms_utility.get_time tool (gives binary_integer type value).
1/ Initialize you time and date of beginning :
v_beginTime := dbms_utility.get_time ;
2/ Run you procedure...
3/ Get end-time with :
v_endTime := dbms_utility.get_time ;
4/ Thus, calculate elapsed time by difference :
v_elapsTime := v_endTime - v_beginTime ;
This will give you time elapsed in of 100th of seconds...
Then you can format you result to give correct print time.
Hope it will help you.

Slow, then fast execution of same query

I have a test query:
dbxml> query 'count(collection()/Quots/QuotVerificationInstance/@lastModifiedDate[.="2009-09-07"])'
With this index:
Index: node-attribute-substring-string for node {}:lastModifiedDate
The first time I run the query in the shell, it takes a while:
Query - Finished query execution, time taken = 29656ms
The second time I run the query, it's a more acceptable speed:
Query - Finished query execution, time taken = 735ms
Can anyone explain the difference in search speed? The slow, fast pattern is pretty consistent (I've tried fresh shell sessions a few times and get the same initial slow search followed by the quicker one.)
What I'm trying to do is allow on-demand generation of a table showing the number of records modified per day and per month. The test date I'm searching for above is the date of insertion of records so it returns a comparatively large result set at the moment, but 29-odd seconds is way too slow to make the query comfortable. I've added a substring index because sometimes I want a partial date search (e.g. when counting records modified per month). I remember reading that a substring index doubles as an equality index. The date is stored simply as a string, not a date type.
What am I missing? I'd like to understand the difference in execution times, but basically I need it to run more quickly for simultaneous date queries. I'd be grateful for any pointers.

Hi Viyacheslav
I think it's perhaps too much trouble for us both for me to try and share the container -- my managers would want assurances about copyright (the data is part of a previously published dictionary), and I'd have to build a smaller one as the current file is > 500MB. But thanks for your interest.
My container setup is pretty simple. It's around 45000 small XML files added to a node container for a read only database (no environment). I have 16 indices supporting a range of different searches and a couple of reports, and the only index relevant to the @lastModifiedDate search is the node-attribute-substring-string index mentioned above (when I tried other edge or equality indexes I deleted the substring index). The query script I intended would be instantiated purely to run the one query and then die each time, so I don't see there being any chance of getting past an initial slow query if that's the behaviour. Because that first query finds around 37000 matches among the 45000 dates, it's understandable that it would take a while but I'm not sure why it speeds up in the shell from the second time round. An obvious suggestion would be that some form of optimisation is taking place in the shell, but I don't understand the workings of DBXML well enough to guess how. Even if this is the case, knowing that it happens wouldn't help me speed up my query due to the life cycle of the script.
Perhaps I should just generate these stats on a daily basis rather than generating them on-demand, or else try a different approach at getting the counts. But thanks again for the comments.

Have you considered using

Alternatively you could provide some more information such as an execution plan for your query:

Can we show comments in adhoc query?

Hello All,
       Can we put comments in Adhoc query?
       I have a comment icon in infotype 9903.
       I need to fetch that particular comments and show in a query output. It is not a field.
       Can we do this? If yes, then please let me know how?
Cheers,
Darshna.

I did it sometime back. A bit complicated process.
Create an infoobject, manually enter the values "keyfig1" and "keyfig2".
Include this infoobject in the filters and restrict it using a "ready for input" variable.
Now create two formula variables.
Write a customer exit such that when you select "keyfig1", first formula variable's value should be set to 1 and other one's to 0.
Then in the query create two calculated key figures, multiply both with the formula variable. Also supress column (all active value == 0).
Then it will show the key figure which you have selected.

Can not select and delete a query in the screen designer

I am getting mad with that problem...
The problem is that I had a query(query1) based in another query(query2), both created in the query designer.
I think some changes been made to query2 so query 1 was giving some erros.
I am trying to delete query 1, but it still appears in the data sources.
And when I try to erase it from the screens, when I select the query visual studio closes...
So please, how can I erase that query definitely?
Thank you for your help!

How can i suppress columns in ALV ?? Will reward points.

Hello Gurus, how can i suppress column in ALV when i`m using the transparent table:
CALL METHOD grid->set_table_for_first_display
      EXPORTING
        i_structure_name = 'ZIANEXE'
        is_layout        = wa_layout

      CHANGING
        it_outtab        = itab[]
        it_fieldcatalog = fieldcat.
Please help.

in the fieldcatalog you are providing there is a field NO_OUT use this.
Loop over internal table and check fieldname. If fieldname = column you want to hide, NO_OUT = 'X'.

Can we use Result from another query in Webi using Bex uery universe?

Hi,
Can we use Result from another query filter option in Webi to create a report using a Bex Query universe?
I need to create a report using two universes, one is Bex Query Universe and the other is Orcle universe. I have two queries, one is using Oracle universe; the other using Bex Query universe. I need to pass the Oracle data from the Oracle query to the Bex Query query to get the matched data from SAP Bex query.
I used Result from another query in the query filter panel for the query using Bex query universe. But I got an error saying that 'A filter contains a wrong value. you cannot run this query. (Error: WIS 00007). The data used in the filter on both sides are the same. they are char.
I have tested by using two queries from the same Bex query universe to see if the Result from another query filter option works. And I got the same error.
Has anyone run into the same issue and if this is possible and what should be the solution?
Thanks in advance!
Edited by: BO_Haiyan on Oct 6, 2010 3:47 PM

In that situation:
Create two queries : Oracle and BW query.
@ Report:
As you have to see result set from both the Dataproviders, correct? To achieve thise one must have common dimension objects to merge them at report and use Objects those are coming from both queries to use them in single Table/Report.
Unless you don't use Merge Dimensions, you don't get a chane to use both queries objects in single Table/Report. (It will give tooltip saying: You can't drop here -- Incompatable Objects)
In case, if you don't have common dimensions, change object definitions to Detail objects, for those required.
Hope it helps you.
Thank You!!

How can I evaluate the count of a query I'd like to execute with a map...

Hi. I have a problem with a query...
I hava created a query which a execute with a Map (I use the
executeWithMap(Map) method). The problem is that sometimes this query
returns a large resultset. So, I would like to execute an other query
(called query_count) before executing ther final query with the Map. If
the query_count returns a count < 200, I execute the final query. How can
I do ? There is an example I have read this in the documentation :
Query query = pm.newQuery (Magazine.class, "price < 5");
query.setResult ("count(this)");
Long count = (Long) query.execute ();
The problem in this example is that the query is not execute with a Map.
So my question is : "How can we do the evalute the count of a query we
would like to execute with a map ?". Thank you for any response.

Hi John,
You should be able to executeWithMap that query, too. Is that giving you
problems?
Note that there may be an easier solution. What do you do if there are more
than 200 results? If, e.g., you just get the first N, then one option is to
set the FetchBatchSize on the query to N (thus activating large result set
support), and then call size () on the resulting Collection. This will
issue a SELECT COUNT(*) to the database to determine the size automatically.
Thanks,
Greg
