| Hi,I have an after trigger which runs when an update takes place against a table in my database.The trigger contains a section of code which is only executed when a specific column has been updated and that piece of code performs a further update on that columns; so for example:If update(column1)set column 1 = 'test'Is this kind of trigger, which would essentially lose the original updated value, supported in SQL server?Thanks. |

| It is called as recursive trigger.You can set it explicitly on with default being off.In off condition the trigger will fire once & then if SQL Server finds that it has recursively fired the same trigger it will perform one more update & stop.Limitations live only in our minds. But if we use our imaginations, our possibilities become limitless. PBUH |
