How can I change these into columns? - sql

Question

I've tried using CTE, but haven't been able to figure it out. I want to change the multiple rows into one row with multiple columns going accross. Any way to go about this...
Current Result
ern CostPool
111 NULL
111 5
Desired Result
ern CostPool1 CostPool2
111 NULL 5
SELECT first_name, last_name, ern, pc, title, TitleDesc, OfficeTitle, SUM(earned) earned, fypaydate, q
, [RMTS, Support, or Partial Quarter], SUM(CAST([Staff Employment Status] AS INT)) sumEmpStatus, SUM(CAST(countisMHy AS INT)) sumcountisMHy, SUM(CAST(sumisMHy AS INT)) sumisMHy1
, SUM(CAST(sumEligible AS INT)) sumEligible1
, CostPool
FROM (
SELECT
e.first_name, e.last_name
, fss.ern
, fss.pc
, fss4.title
, u.OfficeTitle
, t.TitleDesc
, SUM(fss.gross*fss.[percent]) earned
, fss.fypaydate, fss.q
, cpayfss3, cpaypdq
, CASE WHEN cpayfss3 = cpaypdq THEN '1' --full q
WHEN cpayfss3 < cpaypdq THEN '2' --part q
ELSE 'Check'
END [RMTS, Support, or Partial Quarter]
, CASE WHEN COUNT(DISTINCT rc.isMHy) = 2 THEN '9' --split
WHEN fss.pc = 'A' AND COUNT(DISTINCT rc.isMHy) = 1 AND SUM(CAST(rc.isMHy AS INT)) > 0 THEN '1' --full
WHEN fss.pc IN ('X', 'O', 'W', 'L', 'K') AND SUM(CAST(rc.isMHy AS INT)) > 0 THEN '2' --part

END [Staff Employment Status]

, SUM(CAST(rc.isMHy AS INT)) sumisMHy

You can look into using the Pivot operator to convert your rows into columns.
https://technet.microsoft.com/en-us/library/ms177410(v=sql.105).aspx
That method would work, although your sample data and expected result do not quite match the massive query you have posted so I cannot provide a more specific example until you provide more test data/expected outputs (and table schema).
