Run interactive report only if the search filter values / entered.

Hello

I have an interactive report I want to post, but the problem is that too many files are in the base table, so I want to hide this report until some filter values are entered in the search field (apexir_SEARCH), so if no value entered search I do not show the report but with the search value view the report with the returned records ,


I tried to create a hidden item (P1_TEST) USE THE CONDITION relating to THE report if P1_TEST IS NOT NULL, and then submit the report, but it does not work well enough


Thank you

Add to the WHERE clause of the query of the IR (or add it in the WHERE clause if the report has not one):

and exists (select
                null
            from
                apex_application_page_ir ir
                  join apex_application_page_ir_rpt irr
                    on ir.interactive_report_id = irr.interactive_report_id
                  join apex_application_page_ir_cond irc
                    on irc.report_id = irr.report_id
            where
                ir.application_id = to_number(:app_id)
            and ir.page_id = to_number(:app_page_id)
            and ir.region_name = 'Conditional IR'
            and irc.condition_type in ('Filter', 'Search')
            and irr.session_id = :app_session
            and irr.base_report_id = (select apex_ir.get_last_viewed_report_id(to_number(:app_page_id), ir.region_id) from dual))

The predicate will be true only if the user has created at least a filter/search condition for the report, and if it is false, that it must stop the optimizer to hit the base table. (This has been developed and tested on APEX 5.0, so there may be differences with previous versions.)

Note that using the search field by default generates inefficient queries. If you are really serious about performance, clear the search field and get users to create filters to specific columns, which will have a better chance to allow the optimizer to use indexes or improve the execution plan.

  • Interactive reports will change the order of columns

    Hi all

    Have experienced this for the 3rd time now. The other times I just create a new report with the request in the order you wish to fix. But it starts to become annoying now...

    When I use the arrows to change the column order on my reports interactive nothing happens when running. The new order is saved and appears that way in design mode, but does not change the order on the report.

    Please let me know if you know how to solve this problem, or if Miss me just something really obvious.

    Thank you!
    K

    Hey,.

    Changing the order in the attributes report is more an effect, since the default report parameters overwrite it.

    If you want to change the order of the columns, you must go through the menu actions of the interactive report, then choose the column selection menu item, change the order and press ok.

    Then save this order order by default, you go to the action menu again and choose save report option this time, select "primary" or "Save as default" depending on your version of apex (this option is available only if you are connected as a developer in the generator of the apex). Then press the ok button again.

    Other users will only see the changes if they press the reset button on their version of empathy.

    I hope this helps.

  • You try to run a report to view the comments of the CPU usage in vFoglight 6.0

    I am trying to run a report to view the comments of the CPU in vFoglight 6.0 usage, as I have a couple of VMs that seem to cause problems. I want to see what that levels of CPU for a while inside the virtual machines, but I only seem to be able to find the data in the reports for the use of the host processor.
    Any help is welcome

    If you want to use canned reports, which I think will work for what you ask, there is a pre-built for you.
    Home > reports > report > select the right model under all report templates ("using the virtual machine CPU and time ready" looks like the report that you want to")
    for the service should work the vCenter. This will send you all the hosts and any use of the VMs UC over what period you set (default is 4).

  • How do I run a script only if the field is not empty

    How do I run a script only if the field is not empty

    Well well, thanks to you, I had a full date on separate days, the months and the years in different areas. But now, I have a problem, as PDF has several fields calculated with script if you enter the date calculated by all other areas, which have separated and undefinied gives me does not want to put this to not always use this field. I tried to put one conditional if else but I sale. Esto, this is what I'm wearing

    var datesol = event.value;//declaramos the variable

    If (datesol = "") {}

    this.getField('yearsol').value = "";

    this.getField('monthsol').value = "";

    this.getField('daysol').value = ""}

    else {}

    var array_datesol = datesol.split("/"); / / separamos esa con date the split funcio

    this.getField('yearsol').value = array_datesol [2];

    this.getField('monthsol').value = array_datesol [1];

    this.getField('daysol').value = array_datesol [0];

    With what they do not separate them now.

    Help please

    As mentioned, you cannot use

    If (datesol = "")

    because that sets the value of datesol to «» (you will need to double for the comparison operator =)

    If you want to run code only if it is NOT empty, while it takes:

    If (datesol <> "")

    Hello

    01. in the report Footer region put this

    
    

    * This will hide your filters, highlight conditions

    02. then Goto 'Report attributes' => 'Search Bar' => for 'Include search bar' select 'no '.
    * This will hide the full search bar (do this only if you want to hide this part)

    * If you get the answer then mark as 'Correct '.

  • The search filter - how to get the value of the metadata entered by the user

    Hello

    I wrote a fixUpAndValidateQuery filter where I want to modify search QueryText.

    I tried to update some of the metadata values entered by the user and then let the fire search query.
    But I'm unable to get the values of metadata user has entered in my java code filter.
    I'm getting like below

    DocType string = binder.getLocal ("dDocType");

    It returns the value "no" even if the user gives the value of the Doctype in the search engine.

    Am I missing something here?

    Kind regards
    Rajendra

    Search filters tend to manipulate the query that ends up being called by the search service. If this isn't what you're trying to accomplish there are probably better filters for you before the actual query is run or after the query is executed.

    If you really need a connection of database at the moment and you can't find a better filter for what you're trying to do that has a database connection, you can always create one like:

    final Provider dbProvider = Providers.getProvider("SystemDatabase");
    final Workspace myWorkspace = (Workspace) dbProvider.getProvider();
    

    Warning: If configure you your own db connection for a filter where no database connection is available, you will need TO release the connection too.

    myWorkspace.releaseConnection();

  • Interactive report based on the view

    Hello!

    I just started to rewrite my apps of forms at the Apex.
    Based on an existing view, I want to create an interactive report, but there is only the choice between 'Table' and 'SQL statement'.
    Is it possible to use the view directly (not in a SQL ' select * view)?

    Concerning
    Pietja

    Hello Pietja,

    In my APEX env (3.2) an IR cannot be based on a SQL query. You can use the Query Builder to select a table or view, but still he ends with an SQL statement.

    Hello Arnoud,

    If you want to hide option to set a Break control: turn this option off in the area of the search bar of your definition of attributes of interactive report.
    If you just want to hide the image when a Break of control is used in a standard definition of IR: put the javascript $x_Hide ('apexir_CONTROL_PANEL_COMPLETE') or $x_Hide ('apexir_CONTROL_PANEL') in the footer of the region.

  • difference between Interactive Reporting (IR) and the reports of Production (PR)

    Could someone tell me the difference between IR and PR Version 9.3.1 or later if its important. My impression is that IR is used for ad hoc reporting, and PR is used for the production of regular reports. I believe you can also create reports that production of IR also, so I don't see where is the difference.

    Thank you
    Tom

    Hi Tom,

    PR or HYPERION SQR PRODUCTION REPORTING focus produces high quality reporting mass. The reports are designed and then demand by admins (or report developers), end users are generally not involved.

    IR or creation of INTERACTIVE REPORTING, HYPERION focuses on ad-hoc data analysis. IR can be put in place to enable end users to modify queries for the purpose of analysis and output then reports or dashboards.

    Here are the 2 cheat sheets:
