I have a select statement with multiple joins I also have a blank column in SQL statement I want to update the value of this NULL column which I created with the values of another column which is also in the same select statement.
I tried update statement but it did not work.

null as loan_group
,[Loan Number] as loan_number
,[DateofNote] as open_data
,[lnamount] as original_note_amount
,[EOM Balance] as current_principal_balance

INNER JOIN tblLoanStatus LS ON LS.[Status ID] = B.Status
INNER JOIN SCHOOLS S ON S.SchoolNumber = b.SchoolNumber
INNER JOIN [School Types] ST ON ST.[School Type ID] = S.SchoolID

I want to replace the first column loan group such that if the status is 6 or 4 "R" else "P"
Use CASE with IN clause
SELECT
case when status IN
('6' , '4' )
then 'R'
else 'P'
end as loan_group
,[Loan Number] as loan_number
,[DateofNote] as open_data
,[lnamount] as original_note_amount
,[EOM Balance] as current_principal_balance
,b.status
FROM
tblbordata2 B
INNER JOIN tblLOANDATA2 L ON B.
[Student ID] = L.[Student ID]
INNER JOIN tblLoanStatus LS ON LS.
[Status ID] = B.Status
INNER JOIN SCHOOLS S ON
S.SchoolNumber = b.SchoolNumber
INNER JOIN [School Types] ST ON ST.
[School Type ID] = S.SchoolID
Put this in the code for the column you are trying to insert:
SELECT
case when loan_group is null then
case when status = 6 or status = 4 then 'R'
else 'P'
end
end
,[Loan Number] as loan_number
,[DateofNote] as open_data
,[lnamount] as original_note_amount
,[EOM Balance] as current_principal_balance
,b.status
