Report row buttons firing a dynamic action

Image
A lot of the time on reports of data, we'll define a link column, and specify an image which is the beloved pencil icon. Which is good and all, but looking in the Sample Database Application (packaged application), they have taken a different approach to style links - a button that stretches the width of it's containing cell. So, the UI ends up looking like so: So, is this done? Well first, you define a new column for the placeholder. Suppose I want my link column to be Report, I define an extra column in my query: , 'Report' report_link Then I need to go to my new column's attributes, and change the column type to a link. And, in the link attributes, set the text to what you want displayed. Here, I'm just going to display the value of the new column and point to my desired page. So I set the target page, then also the Link text as #REPORT_LINK#. At this point the report will just show link text, as we expect. So, then to replicate t

Accessing the last request value from a page submission

Image
When you submit the page, you will typically have page processes that run. For me, I use these request values to determine which processes are run. This is rather straight forward for on submit processes as you can just specify the condition request = Expression 1 Or, if you have multiple requests that link to this process, Request is Contained within Expression 1, and Expression 1 would be a comma delimited set of values. Request simply refers to the bind variable :REQUEST (or apex_application.g_request). If we try and do the same on a page rendering process, we no longer have access to this value - which makes sense. If you update the branch, to set the request portion of the URL, we will then be able to access the bind variable :REQUEST in all page rendering processing points. This has the obvious downside that if the user wants to reload the page,  clicks in the address bar and hits enter (or clicks refresh), the processes on that condition

Installing Oracle Instant Client on Ubuntu

Now that Oracle has enabled us to download instant client without any click through for accepting the license , I wanted to revisit a seamless install of the instant client on a new set up. Ubuntu has the documentation about installing the instant client here: https://help.ubuntu.com/community/Oracle%20Instant%20Client. First - because Oracle provides their releases in RPM archive format (or a tarball), in order to have an installer you need to create a DEB archive. There is a package in the archives, alien, which aids this process. This gives the start of the script: #!/bin/bash # Install dependencies sudo apt install alien The 3 packages the Ubuntu documentation tells us to retrieve are: - devel - basic (I opt for basiclite instead) - sqlplus So, over at the downloads page: https://www.oracle.com/database/technologies/instant-client/linux-x86-64-downloads.html we can grab the link. # Download files. Example specific to 19.3 # Some links were not correct on the do
