Remove repeating letters

User_F2HJQJan 8 2013 — edited Jan 8 2013

We have a string token with all small leters (Sample - abcdaeebfghiejklc)

Need to remove all the repeating letters in this tring. Output should be abcdefghijkl

I know how to do it by splitting the string into multiple rows, then use listagg to make it a string.

But can we do it use without using any kind of row generation. By regexp or something?
