Body
I am implementing a database design that has a vehicle table, vehicle engine and vehicle gear table with SQL 2005. Each table has an ID that is a SQL identity number, and each engine and gear has a relation with the vehicle ID. So before I create a vehicle I must create an engine and gear. How could I know the vehicle identity number when creating the engine and gear? The vehicle row hasn't yet been created because of the foreign key constraint with the engine and gear tables? Should I implement an automatic trigger that on a creation of a vehicle creates an empty row for the engine and gear linked to the vehicle? But again how could I know the vehicle ID?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
