Pivot without aggregate function - sql

Question

I am trying to turn some parts of my rows into columns. To my knowledge, I am only able to use a pivot with an aggregate function,but I would just be pivoting text. For each client I have up to 4 rows grouped by a DLSEQUENCE field. Instead of having the 4 rows, I would like everything to be on 1 row.
SELECT CASE
WHEN Sched_time BETWEEN TRUNC(SCHED_TIME) + INTERVAL '8' HOUR + INTERVAL '30' MINUTE
AND TRUNC(SCHED_TIME) + INTERVAL '14' HOUR + INTERVAL '45' MINUTE AND
TO_CHAR(SCHED_TIME, 'DY') IN ('MON', 'TUE', 'WED', 'THU', 'FRI')
THEN 'ABC'
ELSE 'DEF'
END AS Organization,
Client_Last_Name,
Client_First_Name,
Sched_Time,
Field_Name,
CASE
WHEN Recoded_Response = '1' THEN 'Yes'
WHEN Recoded_Response = '2' THEN 'No'
ELSE Recoded_Response
END AS Responses,
Dlsequence
FROM DAILY_LOG_CUSTOM_DATA
WHERE SERVICE_NAME = 'Medical'
AND FIELD_CATEGORY = 'Background Information'
AND Field_Name IN
(
'Restraint?',
'History',
'Findings',
'Treatment'
)
AND Sched_Time >= TO_DATE('2020-03-01 01:00:00', 'YYYY/MM/DD HH:MI:SS')
AND Sched_Time < TO_DATE('2020-03-31 12:59:00', 'YYYY/MM/DD HH:MI:SS')
Order BY Dlsequence
Here is my table:
I would like the response fields that go with ('Restraint?','History','Findings','Treatment') to have their own column for each DLSEQUENCE field.

The following should do what you had in mind:
SELECT DLSEQUENCE,
ORGANIZATION,
CLIENT_LAST_NAME,
CLIENT_FIRST_NAME,
SCHED_TIME,
LISTAGG("Restraint?", ',') WITHIN GROUP (ORDER BY DLSEQUENCE) AS "Restraint?",
LISTAGG("Findings", ',') WITHIN GROUP (ORDER BY DLSEQUENCE) AS "Findings",
LISTAGG("History", ',') WITHIN GROUP (ORDER BY DLSEQUENCE) AS "History",
LISTAGG("Treatment", ',') WITHIN GROUP (ORDER BY DLSEQUENCE) AS "Treatment"
FROM (SELECT DLSEQUENCE,
ORGANIZATION,
CLIENT_LAST_NAME,
CLIENT_FIRST_NAME,
SCHED_TIME,
CASE
WHEN FIELD_NAME = 'Restraint?' THEN RESPONSES
ELSE NULL
END AS "Restraint?",
CASE
WHEN FIELD_NAME = 'Findings' THEN RESPONSES
ELSE NULL
END AS "Findings",
CASE
WHEN FIELD_NAME = 'History' THEN RESPONSES
ELSE NULL
END AS "History",
CASE
WHEN FIELD_NAME = 'Treatment' THEN RESPONSES
ELSE NULL
END AS "Treatment"
FROM YOUR_TABLE)
GROUP BY DLSEQUENCE,
ORGANIZATION,
CLIENT_LAST_NAME,
CLIENT_FIRST_NAME,
SCHED_TIME
