Hi

We need to have a mass delete from a table A after some process execution and that deleted data is to be archived into a table B before the deletion. We would like to know which one would be faster in SQL server –

1) A trigger on delete upon table A

2) Copy data from table A to table B based upon deletion conditions and then delete from table A

Any other alternative suggestions are also welcome.

I think option 2 will be better.

See http://weblogs.sqlteam.com/peterl/archive/2007/10/03/New-OUTPUT-operator.aspx for more information

DELETE     a
OUTPUT     10 * deleted.i + 49
INTO       #TableB
FROM       #TableA AS a
WHERE      i = 2
