Documenting primary and unique keys

Applies to: Dataedo 23.x versions, Article available also for: 24.x (current), 10.x

Primary and unique keys

Dataedo imports table primary and unique keys. Those unique keys might be unique indexes or unique constraints in case of Oracle. They are presented in one table in Unique keys tab.

To describe unique keys edit text in description field.

Unique keys

Missing logical keys

Sometimes, a logically existing primary or unique is not physically coded in database. Similar logical constraints may also exist on views. Dataedo allows you to add them both to your tables and views by using user-defined keys.

Adding user-defined primary or unique keys

Note: User-defined unique keys and relations exist only in Dataedo repository and are not populated back to database schema.

To add user-defined primary or unique key for your table/view go to Unique keys tab and click Add primary key or Add unique key button on the ribbon or from context menu under right click.
