I've got a "features" table with a "part_number" column in it that needs to be updated according to the "feature_door_id" column in the "doors" table.

There isn't a real relationship between those two tables, however...

There's a "product_id" column in the "products" table that can help, I just don't know how to structure this update statement that makes the correct association.

It looks like this:

I want to use the relationship that exists between the three tables to help me update what's in the "featured_door_id" column to the "part_number" column in the features table.

How?

Maybe I missed something. It looks like you have a related product_id column in both the doors and features tables.

If that is the case, in T-SQL it would look like this:

UPDATE f
SET f.part_number = d.featured_door_id
FROM [featurestable] f
INNER JOIN [doorstable] d ON d.product_id = f.product_id

Open in new window


Good luck!
