add a case statement to three existing columns. Else do substring

select column1 from table1

if column1='bob', write 'bob evans'

select case column1 when 'bob' then 'bob evans' else column1 end as MyColumn
from table1


How to add this new case statement to this existing query
select substring(profile_id,1,3),substring(sender,1,3),message_id, substring(this_user,1,3)

where 'bob' can be profile_id, sender, this_user

NOTE: I want 'bob evans' else three letters of column name
Do not do substring if 'bob evans'
