Get value of two columns when pivoting - sql-server

Question

I have a table that has entries like
Acct Nurse EntryDateTime DBCode Answer FormSeq
123 Sally 9/8/2020 09:22 Code1 Ans1 0001
123 Jim 9/8/2020 10:25 Code1 Ans2 0001
123 Sally 9/8/2020 09:15 Code2 C2Ans1 0001
I have a query that is pivoting this to get the answer from the last entry based on DBCode and EntryDateTime that works great. What I need to do is get the NURSE as well as the answer.
So my row would be
Acct Code1 Code1Nurse Code2 Code2Nurse
123 Ans2 Jim C2Ans1 Sally
Is there a way to do this? I would need the nurse for each unique DBCode
Here is my pivot code:
SELECT * FROM (
SELECT
[AcctNumber],
[Answer],
[DBCode],
[EntryDate],
[FormCode],[FormSeq]
FROM V_FAC_MULTIAPP_FORM_WITH_HOURLY
) MultiApp
PIVOT (
MAX( [Answer])
FOR [DBCode]
IN (
[AST],
[SDRM],
[SDRF],[SDAAS],[SDDCT],[SDDAS],[SDABY],[SDDAT],[SDTRCC],[SDADMTW],[Prptic],[Pdcrt]
)
) AS PivotTable WHERE EntryDate >='8/15/2020' and FormCode='LL003' ORDER BY EntryDate

Answer 1

You could use conditional aggregation.
Data
drop table if exists #tTEST;
go
select * INTO #tTEST from (values
(123, 'Sally', '9/8/2020 09:22', 'Code1', 'Ans1', '0001'),
(123, 'Jim', '9/8/2020 10:25', 'Code1', 'Ans2', '0001'),
(123, 'Sally', '9/8/2020 09:15', 'Code2', 'C2Ans1', '0001')) V(Acct, Nurse, EntryDateTime, DBCode, Answer, FormSeq);
Query
;with rn_cte as (
select *, row_number() over (partition by DBCode order by EntryDateTime desc) rn
from #tTEST)
select Acct,
max(case when DBCode='Code1' and rn=1 then Answer else null end) Code1,
max(case when DBCode='Code1' and rn=1 then Nurse else null end) Code1Nurse,
max(case when DBCode='Code2' and rn=1 then Answer else null end) Code2,
max(case when DBCode='Code2' and rn=1 then Nurse else null end) Code2Nurse
from rn_cte
group by Acct;
Output
Acct Code1 Code1Nurse Code2 Code2Nurse
123 Ans2 Jim C2Ans1 Sally

Answer 2

Here is something to play with. It would take some tinkering, but you could make the query dynamic to build out the columns to select based upon the DBCodes you have in your table...
IF OBJECT_ID('tempdb..#V_FAC_MULTIAPP_FORM_WITH_HOURLY') IS NOT NULL
DROP TABLE #V_FAC_MULTIAPP_FORM_WITH_HOURLY;
CREATE TABLE #V_FAC_MULTIAPP_FORM_WITH_HOURLY
(
Acct INT,
Nurse VARCHAR(20),
EntryDateTime DATETIME,
DBCode VARCHAR(10),
Answer VARCHAR(10),
FormSeq VARCHAR(10)
)
INSERT #V_FAC_MULTIAPP_FORM_WITH_HOURLY
VALUES
(123,'Sally','9/8/2020 09:22','Code1','Ans1','0001'),
(123,'Jim','9/8/2020 10:25','Code1','Ans2','0001'),
(123,'Sally','9/8/2020 09:15','Code2','C2Ans1','0001');
WITH Top_Row_Per_DBCode_By_EntryDate AS
(
SELECT ROW_NUMBER() OVER (PARTITION BY DBCode ORDER BY EntryDateTime DESC) AS top_row,
Acct,
DBCode,
Nurse+':'+Answer AS Answer
FROM #V_FAC_MULTIAPP_FORM_WITH_HOURLY
), Filtered_CTE AS
(
SELECT *
FROM Top_Row_Per_DBCode_By_EntryDate
WHERE top_row = 1
)
SELECT Acct,
Substring([Code1],CHARINDEX(':',[Code1])+1,LEN([Code1])-CHARINDEX(':',[Code1])) AS Code1,
Substring([Code1],0,CHARINDEX(':',[Code1])) AS Code1Nurse,
Substring([Code2],CHARINDEX(':',[Code2])+1,LEN([Code2])-CHARINDEX(':',[Code2])) AS Code2,
Substring([Code2],0,CHARINDEX(':',[Code2])) AS Code2Nurse
FROM Filtered_CTE
PIVOT
(
MAX( [Answer]) FOR [DBCode]
IN ([Code1],[Code2])
) AS PivotTable
