[mso] Re: ACCESS - Update Records

Well, yes, that is what I need to do, but it's not with every single field. 
Maybe with an example you can see why I would want to do that...

Let's say I have a table with with orders, and I have another table with 
products for sale. When entering an order, I will enter in the product ID and 
through the relationships it will automatically fill in the product description 
and price. 

Now, in the future, I may need to change the product ID, for whatever reason, 
and I would need the product ID to change in all the records its been entered 
in as well. So, there, its ok for everything to change.

On the other hand, let's say the price changes. Well, in the past orders, I 
need to show what the price was at the time the order was entered, NOT what it 
is currently. So, if I change the price in the PRODUCTS table, I cannot have 
the price change in orders that have been entered.

So, the question is, how would I allow this in some fields, but not others.

Thanks!

  Charlie,

  Are you saying that you want to change data that is linked but not have it
  changed everywhere it has already been entered?  It sounds like you may be
  trying to violate referential integrity which isn't necessarily a good idea.
  If you do want to do it, you can simply uncheck the box to enforce
  referential integrity on the relationships.  Be very careful with doing this
  though.  It will allow you to have "orphaned" records in your database.

  I have my tables and forms set up. I have my relationships between all the
  tables set up as well. Now, using a form, when I enter data in one field, it
  will automatically add the correct info in related fields. Fine, as that's
  what I want.

  However, sometimes I might change data in a field from a table and I do NOT
  want it to update in existing records... how would I go about doing this?

  If I didn't explain that correctly, let me know and I'll rephrase my
  request.

  Thanks!
