CLOB in APEX Rich Text Editor

3 July, 2020 22 Comments

This post is valid up to Oracle APEX 20.01 version, when there is CKEditor version 4. From APEX 20.02, when creating new Rich Text Editor page item, it’ll be created as CKEditor version 5 and parts of the codes below won’t work.

It’s been a while since the last time I posted something, but there were no new challenges, which always inspire me to share the solutions with you, until last week. I was tasked to build dynamic surveys, where users can define their own questions. This resulted into decision of building a function in a package, which returns HTML of the survey in CLOB. In another application we already used load and save CLOBs so I reused the code and behold, I got apex.ajax.clob is not a constructor error. What caused the error and how to solve it is what I’ll be talking about today. If you are interested about an article about surveys, I might do it in future, but now I’ll focus more on the standard use of CLOB column in application and that’s using it together with APEX Rich Text Editor.

Last week I wrote about how to setup your Web Source and how to create report from it as source. Lastly, I explored the external filters and order by functions and how to use them. This time, I’m going to talk about caching of the web source and why not to use the external filters and order by.

Welcome back to my blog. It’s a while since my last blog post, but the lack of interesting or worth sharing stuff made me go on hold for over a half year. That changed with the last request I got. Due to some reasons we have internal application which we currently develop, but we want to expose part of it to the big bad Internet. Due to the nature of the Internet we won’t be risking exposing the application itself and we only create reporting application, which will connect to only specific objects in database remotely, so we limit the risk of exposing data we don’t want to expose.
