Assign Primary Keys
You can configure primary keys on the currently displayed, unsaved table document. You must assign primary keys to table columns before you can create foreign key constraints.
Note: Primary key functionality is available for Actian Vector tables if the table is newly created and empty.
Before you can assign table columns as primary keys, a table must be created but not yet saved.
You can assign primary keys in the following ways:
• From the new table document context menu: Set Primary Key
• From the new table document context menu: Indexes/Keys

The primary key node is added to the Keys folder of the selected table in the Instance Explorer.
After you have assigned primary keys, you may
create foreign key constraints (see
Create a Foreign Key Relationship).
