Trent's Tech Tips

One of the statements of direction for APEX 5 is multiple interactive reports on a single page. Multiple Interactive Reports – Allow any number of Interactive Reports to be defined on a single page. So, time to explore that functionality. One pattern I've used in the past is loading particular saved reports (rather than the default primary report). You may have some pre-defined filters, a row highlight, specific columns. So for demonstrations, I've built an IR on the emp table. Then I go and apply some filters, and save an alternate report: Then in the page designer assign an alias to that report. As you can see, that allows me to enter in the request portion of the URL: IR_SAL_TOTAL. However, if we add a second IR to the page and try to access that saved report, we would receive an error "Report does not exist". This is because it tries to find that that report name in both IR's. To get around this, you MUST  set a static ID property fo...

To reset an IR back to the default settings, you may know you can go to the actions menu, and hit reset: If you inspect the apply button you will see it's calling gReport.reset() And there are a bunch of examples using this gReport object both for resetting the report and other IR functions. https://community.oracle.com/thread/2186564 https://community.oracle.com/thread/2595066 http://www.apex-at-work.com/2010/03/building-ir-filters-with-ajax-not.html http://www.apexninjas.com/blog/2012/06/the-greport-search-function-for-apex-interactive-reports/ The problem? This is not documented, and with APEX 5 supporting multiple IRs, this will no longer work. In your console, if you enter gReport, you will see that object no longer exists. The other technique you can use is the clear cache portion of the URL. According to the docs : To reset an interactive report in a link, use the string "RIR" in the Clear-Cache section of a URL. This is equivalent to the ...

Around the time of 4.2 coming out, I blogged about the APEX_IR API, which enables us to get the report query. At the time, I demonstrated nothing more than rendering the resulting query, and listing all the bind variables.  Well, now comes time to put this to use. The scenario. Updating a particular column for all the rows that have been returned from the IR filters and what not. Previously, to do this, I would typically have a hidden item by utilising the APEX_ITEM.HIDDEN API, along with the using the APEX_APPLICATION.G_F0X array in an on submit page process. The downside with this (or upside, depending how you look at it) is it is only good for the displayed results. So firstly, it's important to enforce that some key field is included in the report - so that we can accurately update the data. In an example i've set up, I'm including the ID, then in the column attributes unticking the option that would enable them to hide the column. At the top of a page, I...

Well, yesterday oracle released the first early adopter of application express, having had a chance to have a little play around, these are the ones that caught my attention: APEX_IR See:  http://apex.oracle.com/pls/apex/f?p=38997:1:0::NO:RP,1:P1_MARQUEE_FEATURE:Interactive%20Report%20Enhancements There are currently some interactive reports utility functions/procedures as part of the apex_util package. These will now be deprecated, and functionality will be added to a package named APEX_IR. The most exciting addition is the ability to get the derived IR query (from added filters/sorts). Without any published API docs, I can only assume this is through the function get_report. Further, I set up an example on page 2 of the sample database application. Created a new popup page with a dynamic region with the following source: declare l_report apex_ir.t_report; begin l_report := apex_ir.get_report( p_region_id => 6506762112827941367, p_page_id =>...
