| I have a database that has an item master (tblItem) table and a values table (tblValue) that is related but not with a relationship. An tblItem record can exist without a tblValue record. tblValue records are added after the item exists. I want to change the key (ItemId) of tblItem and have the key in tblValue update (cascade) the change to the ItemId. I don't think I can put a relationship in because the tblValue table will not have records so I cant "enforce" the relationship. Is there a way to change the key in tblItem and have that change update tblValue? thanks,vmon |

| The way this system was set up the user can change the ItemId and it handles changing all of the related tables even though there are no relationships defined. I have inherited this system and the tblValue table was added but not included in the udpate when an ItemId is changed. I am not real sure how to do this. Can I just run an update statement against a key value? |

| In that case, a trigger might help. Make use of the INSERTED and DELETED help tables.Peter LarssonHelsingborg, Sweden |
