Question

Table A(ID, col2, col3, col4)

I want to add a new entry to Table A for every ID given that col4 = ‘certain criteria’ and the value of Col2 from the existing entry will be used as col2 of the new entry. How would I go about accomplishing this task?

The part that is throwing me off is how to do this without using a loop. Any help would be appreciated.

Answer 1

something like that should work

INSERT INTO TableA (col2, col3, col4)
SELECT col2, 'any constant value', col4 FROM TableA
WHERE col4='certain criteria'
--GROUP BY ID (not clear if you need to group by something)
