pattern matching

Is there any way to do the following pattern match in db2?

LIKE '[CK]ars[eo]n' searches for Carsen, Karsen, Carson, and Karson
(Carson).

In other words, the brackets around CK will match anything with a C or
K in the first character.

Thanks.

For simple patterns you can use something like:

select * from T where substr(mycol,1,1) in ('C','K') and substr(mycol,
2,3) = 'ers' ...

For a more general approach, you might find the following article by
Knut Stolze interesting:
