Question

Consider a trigger after update on the table A.
For every update the trigger should update all the records in table B.
Then consider this query:

UPDATE A SET X = Y 

Apparently there are many rows updated. After the update the trigger takes place.
Now if the trigger would be using inserted table, and you would like to update the table B with every single row of the temporary table inserted, and in MSDN is not recommended to use cursors, how would you do that?

Thank you

I don’t know what exactly you want to do in your update trigger, but you could e.g.

UPDATE dbo.B
SET someColumn = i.Anothervalue
FROM Inserted i
WHERE b.Criteria = i.Criteria

or something else – you need to tell us a bit more about what it is you want to do with table B! But it’s definitely possible to update, insert into or other things, without using a cursor and handling multiple rows from the Inserted table.
