Using a CASE statement in HQL select

Question

Is there any way to do the following in HQL:

SELECT 
    case when flag = true then SUM(col1) else SUM(col2)
FROM 
    myTable

Answer 1

This is an example using a string comparison in the condition:

SELECT CASE f.type WHEN 'REMOVE'
                   THEN f.previousLocation 
                   ELSE f.currentLocation 
       END 
FROM FileOperation f
