Can I achive valueChangeListener in af:query?

I've a multi-select component and it is is giving severe performance issue while deselecting from a larger selection. I'm curious to know if I could register/listen to valueChangeListener for af:query attributes?
Appreciate any help or pointers!

I don't know if I'm failing to describe you my use case but I'll try again:
-> In both the example referred by Frank/Jobinesh, the attribute value is submitted/posted before handling further operations described respectively in these posts.
-> But I'm facing the performance issue with a select many choice on af:query, if the select many choice is deselected from a larger selection exceeding 100 rows. The performances worsens if deselection happens as the previous selection increases beyond 100 rows.
-> The below is a forum post describing the performance issue, what I'm trying to see is if I could get the new values for a select many choice on af:query before they were posted (which is causing performance issue), so I could warn the user not to select more than 100 rows.
Multi Select Choice on af:query has severe performance issue

  • 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 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.

  • 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!

    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!!

  • Can I put formula in a query

    I created an infoset (SQ02) and a query (SQ01).  I want to have a new column that computes for the difference of the forecasted sales and actual sales.  Can I do that in a query?

    Hello John,
    I'm sure it can be done. But you have to take the help of an Abaper to acheive that.
    Go to Transaction code - SQ02 (Change mode of the query you have created). Then click on the <b>Extras Tab</b> and use the <b>Code Tab</b> to write the formula you require.

    are you using LE-Transportation?  if yes, there are some helpful t-codes such as VI11 and VI12.  you may also use t-code SQVI for queries, but you would have to know what tables to look for.

  • BI Auth - user still can search & execute for not authorized query

    Hello All,
    need your help here.
    For BI security,
    I've configured menu role (for example ZBEX_FIN) in order for the end users to see only specific queries/workbook inside the menu folder that assigned to him/her.
    And I've made a function role for end user, copy from the template S_RS_RREPU with the modification:
    1. I delete 0BI_ALL
    2. add S_USER_AGR and put my menu role above (ZBEX_FIN) for field ACT_GROUP
    3. add S_RS_FOLD to disable the infoarea button in BEx.
    currently the user can see and execute report assigned in the role menu folder, this is correct.
    But the problem is there's a find button in the BEx, when the user try to search other query (non authorized query,the one that supposed he can't see), he still can display the query, then can execute the query. This is not acceptable.
    Anyone can suggest whether I can disable the find button in the BEx
    or any other restriction in the role that I missed, so the user can only execute and display the query/workbook under the role menu only.
    Thanks in advance.

    So it means that we need to do it twice restrictring the query in the role menu and then inside the S_RS_COMP ?
    so later when the user wants to add more queries in his role, we need to add those in the role menu as well inside the S_RS_COMP. is this correct ?
    When you add queries/workbook to role menu, you are not restricting the access. Its just that user menu would list those queries/workbooks. Users can search for other queries and workbook and run them with proper authorizations in S_RS_COMP. You may consider maintaining query naming convention with wild cards for example YRZ* etc to give access to all queries/workbooks starting with YRZ. This would save your effort to update role too freqeuntly.
    And if I have a workbook, how I put it inside the S_RS_COMP ? because the component of S_RS_COMP is query only.
    S_RS_COMP can restrict queries as well as workbooks with field RSZCOMPTP= REP

  • How can i check when a given query was run

    how can i check when a given query was run ( i mean the timestamp ) from forms
    I am trying to run the query depending on when it was last run

    Hello,
    I'm not sure to really understand your need, but if you want to refresh the data blocks regularly, you can use a timer that would execute_query on the block every elapsed period of time.
    Anyway, there is no "timestamp" of this kind, so that you would store the information somewhere in memory on in a table, from a PRE-SELECT or POST-SELECT trigger for instance.

  • TTIMDB Connection issues: Can't resolve a non-optional query descriptor property [DSN]

    Hi there,
    We currently have the 11g TTIMDB plugin deployed in our EM10g instance without issue and looking to migrate to 12c.  We've installed/deployed the 12.1.0.2.0 plugin into our EM12c instance and deployed it to 12cR3 agent on our TTIMDB dev server.
    When adding the TTIMDB target in the same manner it's deployed in 10g, the connection tested fine to the DB however the target is showing down with the following errors.....
    1. Under Monitoring > All Metrics we get this... "The TimesTen database is down: [data source/db name] is not loaded"
    2. Under Target Setup > Monitoring Configuration we test the connection, and though testing the connection when first configuring the plugin worked fine it's now failing... "
    Response;Can't resolve a non-optional query descriptor property [DSN] (DSN)"
    Any thoughts on what may be causing these errors?
    Thanks,
    Steve

    Maybe you are confusing the main daemon running (TimesTen instance is up) with a specific database being up? When you install TimesTen you create a TimesTen 'instance'. This instance has several daemon components the most critical of which is the main daemon. When the main daemon is running the instance is 'up' and when the main daemon is not running the instance is 'down'. An instance may manage several distinct databases concurrently and those may each be up (in memory) or down (not in memory) independently of each other. In order for anything meaningful to happen within an instance the instance must be up.
    The default behaviour for TimesTen is to load a database into memory when something connects to it, to maintain it in memory while there are open connections and to unload it from memory when the last connection is closed. This can be useful for development and testing environments but is not necessarily the best choice for production environments. Generally, in a production environment, you should set the database(s) to 'manual' ramPolicy:
    ttAdmin -ramPolicy manual DSN
    then you can explicitly load the database into memory (i.e. start up the database):
    ttAdmin -ramLoad DSN
    and, when all connections have been close, you can explicitly shut it down:
    ttAdmin -ramUnload DSN
    Many customers find this a better way to manage production databases than the default behaviour.

  • How can update two rows in one query?

    What do you mean with "two rows"? May be two columns??
    If the where clause of UPDATE query matches two rows, then it will update two rows. If you want to update two columns, then add column names to your query
    UPDATE your_table SET col1=value1, col2=value2 WHERE your_where_clause- - - - - - - - - - - - - - - - - - - - -
