SQL Query (return colon separated value)

Did you know there is a new computation type in APEX - SQL Query (return colon separated value)? Probably not, because there are many other "sexier" features. However this "small" feature is realy cool. Before, you needed to do several steps if you wanted to compute your multiselect list, shuttle item, checkbox or a radio button:

1. DECLARE an array,
2. SELECT * BULK COLLECT INTO array
3. use APEX_UTIL package to convert that array into a string
4. RETURN that string

With APEX 4 you don't need to do that any more. You just do a normal select and whatever it returns will be concatenated into a colon delimited string. That's it.

New Apex Blog

My colleague and friend Linh Dinh from Munich recently started to post about his experience with APEX. You can find his blog here http://www.dinh.de. Linh is a knowledgable and smart person with a lot of Java background. His first contact with APEX was in March this year when we started with a project for one of my customers. He immediately liked it and has made a huge progress since then. Linh is blogging in German and therefore his postings are especially interesting for the German APEX community.
