From Oracle FAQ
is there any function like mysql function group_concat in oracle
Why is there a VARCHAR and a VARCHAR2? This really looks like an attempt to force people to write Oracle specific SQL code. Is VARCHAR2 a standard type?
The answer is in a recent topic in the forum (http://www.orafaq.com/forum/i/102589/) which is the place to post a question.
Wiki Talk is not the place to post a question but new page or comment on page.
