Query to get a character separated list from a result set

I wouldn’t take the credit of this but I found a very cool way of converting an array to a string using hierarchical queries. I found this mechanism in one of my projects and I think it is good enough to be shared

The performance enhancing drug called Table function

Finally a post on APEX :)

I have seen a number of situations in development of both Oracle APEX (Interactive reports) and in Oracle BI Publisher where the developer has to implement complex functionality but he only has the freedom to write SQL statements and not PL SQL logic. Due to this he ends up writing the complex logic using ‘and clause’ and ‘or clause’.
