The first 2 commands work as expected. The third command actually deletes the record it should be updating.

RunCommand("update product set SKU = " + Common.SQuote(Sku) + " where ProductID = " + ProductID);
RunCommand("update Orders_ShoppingCart set OrderedProductSKU = replace(OrderedProductSKU," + Common.SQuote(OldSku) + ","+Common.SQuote(Sku)+") where ProductID = " + ProductID);
RunCommand("update ShoppingCart set ProductSKU = replace(ProductSKU," + Common.SQuote(OldSku) + ","+Common.SQuote(Sku)+") where ProductID = " + ProductID);

I am new to SQL Server and I am using a database that I purchased for an online store.

Anyway, I started playing around in Enterprise Manager and I chose to Display Dependancies.

I noticed that Product doesn't have any dependencies, Orders_ShoppingCart is dependant on Orders, and ShoppingCart is dependant on Product.

Is the fact, that ShoppingCart is dependant on Product and that I changed Product first, the reason?

If this is the case is there a way to remove the dependency and then make the updates and then replace the dependency. I guess I don't understand what a dependency is for.

Thank you,
