| I have a shopping cart and I need to remove items out of stock temporarily when a user adds the item to their cart and then add the quantities back to stock ONLY if the item is greater than 15 minutes.My question is if triggers would be a good solution when a user adds an item to the cart to handle the removal of item quantity? Or is there a better way?Alex |

| If all your database access is via stored procs then you can put it in the stored proc.You will need a scheduled task to check for the timeout to add the item back in.==========================================Cursors are useful if you don't know sql.DTS can be used in a similar way.Beer is not cold and it isn't fizzy. |

| Do a search - you will find lots of discussions.In your particular case it saves having to add triggers. Triggers make the system a lot more difficult to understand as well as holding locks and slowing everything down.==========================================Cursors are useful if you don't know sql.DTS can be used in a similar way.Beer is not cold and it isn't fizzy. |
