Question

http://sqlfiddle.com/#!3/e4891/1

for the above resulting query(which pivots data) I want to run my one more select condition.

For example

select (C1 & C2) from ‘the above pivoted query results’

IS it possible to do it? CTE will help here?
SQL Server 2008 and above.

Try this:

WITH Data AS 
(
  select *
 from 
 (
    select MemId, Condition_id, condition_result
    from t
 ) x
 pivot
 (
    sum(condition_result)
    for condition_id in ([C1], [C2], [C3], [C4])
 ) p
)
SELECT C1, C2
  FROM Data
