Can I get the matching expression from REGEXP

[Mike Bosschaert]

Hi,
In one of my tables I have a column which contains a combination of a string 
(characters only), a space and a 1 or 2 letter combination. The string has no 
fixed lenght. Like:

   abcd ef
   bcdefgh i
   etc

Now I want to remove the 1 or 2 letter combination from this column into 
another column. I can select the rows with 

WHERE colX REGEXP ". .{1,2}$"

This wil return the first two rows only. But I cannot figure out how to get 
the query to return the matching result (being ef and i).

Any help appreciated

Mike
