I have 2 tables.
tblParts
columns: PartID, PartNum, PartPrice
tblPricing
Columns: PricingID, PartID, PartPrice1
When tblParts.PartPrice is updated or inserted i want to insert the new price and the PartID into tblpricing accordingly.
What would be the best way to accomplish this?

You have a few options. One is a trigger, another is the update proc, another is the front-end code.

The easiest and most consistent is probably a trigger, but that does have a few drawbacks (mainly that triggers are pretty much invisible if you forget them, and can be a pain later in that case).

I just don't see a need for the pricing table... all of the required information is in the parts table. There is no need to have duplicate information in the database.
