Question

Is there any way other than using a cursor that I can use SELECT results for a subsequent INSERT/UPDATE query?

Something like:

DECLARE @SELECTRESULT;

SELECT Something into @SELECTRESULT
FROM Somewhere

INSERT INTO SomewhereElse (X, XX, XXX)
SELECT Something, GETDATE(), 'XXX'
FROM @SELECTRESULT

UPDATE Somewhere
Set SomethingElse = 'ABC'
WHERE
Something in
(SELECT Something FROM @SELECTRESULT) 

The reason is that I have a relatively complex query from multiple tables and I don’t want duplicate this code, once for the insert and second time for the update.

You can use a table variable.

Something like

DECLARE @Table TABLE(
Col1 INT
)

INSERT INTO @Table
SELECT Col1
FROM Table
