Question

I have written a simple trigger which sets a column value with the id column value.
This is my trigger.

CREATE TRIGGER SubSectionsPrioritytrigger
ON SubSections
AFTER INSERT
AS
UPDATE dbo.SubSections
SET Priority = Id

After writing this trigger that, does this updates all the records after each insert. Or the only created new row.

Could some one provide any info on this.

Thanks.

To Update just the inserted row, you can do this:

UPDATE dbo.SubSections  
SET  SubSections.Priority = SubSections.Id 
FROM INSERTED
WHERE INSERTED.Id = dbo.SubSections.Id
