Oracle

The query...

select distinct name from myTable

returns a bunch of values that start with the following character sequences...

ADL*
FG*
FH*
LAS*
TWUP*

Where '*' is the remainder of the string.

I want to do an order by that sorts in the following manner...

ADL*
LAS*
TWUP*
FG*
FH*

But then I also want to sort within each name in the standard order by fashion. So, an example, if I have the following values

LAS-21A
TWUP-1
FG999
FH3
ADL99999
ADL88888
ADL77777
LAS2

I want it to be sorted like this...

ADL77777
ADL88888
ADL99999
LAS2
TWUP-1
FG999
FH3

I initially thought I could accomplish this vias doing an order by decode(blah) with some like trickery inside of the decode but I've been unable to accomplish it. Any insights?
