| I have a table [Assets] with several columns. One column name is RetiredDate and second one RemainingDays. I'd like to create a trigger that column RemainingDays is updated by using the future RetiredDate Column and TODAY date.Help much appreciated!Thanks |

| You would need to run that every day which means it couldn't be a trigger (unless you update the table daily).Have you thought of a computed column? Or why not just calculate in the SP when you need to.==========================================Cursors are useful if you don't know sql.SSIS can be used in a similar way.Beer is not cold and it isn't fizzy. |

| Basically, I have an internal website that reports some valuable information like the purchase date and the retireddate of the given asset. I also have a column called remainingdays. It would be nice to have this column continuesly updating as the day to get the system needs to be replaces.Thanks |
