SQL specified sort

От

I was wondering if you could help me out with a problem I'm having. Say for 
example I have data coming out like:
H29
214
200
099

How would I use a sort to be able to make the output look like

214
H29
200
099

I don't believe their is a way to do an ORDER BY in a specific order. Any 
help you could give me this problem would be very much appreciated.

Jeff,

If you want to receive your data in an order which 
you specify manually, the easiest way to accomplish this
is to add a separate field which contains an int4 value
used by you to specify the order.

E.g. 

myval   |   sortint
_____________________H29    |   2214    |   1200    |   3099    |   4


SELECT myval FROM mytable ORDER BY sortint;
