SQL & PL/SQL

Hi
Experts ....here is something for u ppl, which appeared quite tedious for me lets see whether u have got the solution or not.

Suppose I have a table Dump with the following Construct and Value

#Dump
-------
Dcode Varchar2(15);

Dcode
.......
AAABBCCDDEEA
BBDDDFFAACC
DHSGHDADSFDF

NOW i need an output of somewhat like this
Dcode
......
ABCDE
BDFAC
DHSGAF

If its possible to get the desired output in a Single Select statement then i wud say 'Eureka' nor u can help me either with writing Procedure or Function.

Ur help is highly appreciated.

Regards
Vineet
