    <p>Since NoGotnu already answered, I'll put this here: </p> <p>Is there any reason for the procedure to be called through a job? Is it the only way to create the required record? Is the job called anywhere else? Why not call the procedure directly when the required page has been submitted and show the loading icon there? When it finishes, the user knows it has finished. That would involve a lot less fiddling around as you can make apex show a processing graphic on page submit. You could then just inform the user on the other page that the process has not been ran yet and they'd have to do that first.</p> <p>Secondly, while NoGotnu's answer will work, I'd like to point out that in apex 4.2 you should use the <a href="http://docs.oracle.com/cd/E37097_01/doc/doc.42/e35127/javascript_api.htm#BGBJEFDJ" rel="nofollow noreferrer">apex.server namespace</a> instead of the never documented htmldb_Get construction. <a href="http://docs.oracle.com/cd/E37097_01/doc/doc.42/e35127/javascript_api.htm#BGBIIJFC" rel="nofollow noreferrer">apex.server.process</a> is a clean implementation of the jQuery ajax setup. NoGotnu's code translated:</p> <pre><code>apex.server.process( "GET_MY_ROW" , null , { dataType: text , success: function(pData){ if (pData == 1) { clearInterval(myInterval); alert('Record loaded successfully'); }; } } ); </code></pre> <p>The call doesn't really need to be async though, but ok.</p> <p>Another option would be to implement a "long poll" instead of firing the ajax event every 5 seconds. A long poll will just initiate a call to the server and wait for a response. As long as the server is busy, the client will wait. To achieve this you could use dbms_alert, as suggested in <a href="https://stackoverflow.com/questions/4599630/waiting-for-a-submitted-job-to-finish-in-oracle-pl-sql">Waiting for a submitted job to finish in Oracle PL/SQL?</a><br> You'd signal an alert in the plsql code of the job, and in the ondemand process code register an interest in the alert and use waitone/any with a 60 second timeout. Presto long poll.</p>

    1. COHello, Tom! Thanks for your answer. I knew about apex.server.process but i tried to give an example of universal method, that works even at APEX 3.x. About long poll - i think that in this simple task, long poll will be excessive (or redundant? - my english is bad). But you are right anyway ;)

    2. CO@NoGotnu If people are on 4.2 but persist in using htmldb_Get they deserve punishment honestly ;) I understand it was useful, but still consider a jQuery implementation far superior even though it takes a couple of extra lines. To me, it is just more transparent, and I love how apex has expanded on it and gives us a more standardized control. As for long poll: yes, this may be a bit overkill. Still, it should not be hard to implement by using dbms_alert, and kills some of the tediousness having to be done in javascript. But hey, both ways work and having options is a good thing!

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
