INSERT INTO SELECT from UPDATE

Question

I need to select some values from a table to be updated, and then update them right away. Furthermore, I need to insert one new record in a table for each updated record. To select records and update I am using a structure like

UPDATE TableA SET SomeField = 1 OUTPUT RecordID FROM TableA WHERE RecordID IN
(    
    SELECT TOP @Something RecordID FROM TableA    
)

Now, for the insert part, I would like to wrap the UPDATE statement into an INSERT INTO SELECT, thus taking advantage of the OUTPUT clause. However, SQL complains when I do

INSERT INTO TableA SELECT ( RecordID , GETDATE() ) FROM
(
    UPDATE TableA SET SomeField = 1 OUTPUT RecordID FROM TableA WHERE RecordID IN
    (        
        SELECT TOP @Something RecordID FROM TableA        
    )
)

Can't I do it all in one statement, even with the OUTPUT clause?

Answer 1

UPDATE TableA SET SomeField = 1 
OUTPUT inserted.RecordID, GETDATE() into TableA (RecordID , DT)
FROM TableA 
WHERE RecordID IN
(        
    SELECT TOP @Something RecordID FROM TableA        
)

Just not sure - you're trying to insert updated rows again ?
