Question - Is The Primary Key For Sap Maxdb Also Stored In A Separate Index-b* Tree?
Answer -
Each database table has a primary key (primary index). The primary key is either defined by the user or generated by the system. A user-defined primary key can consist of one or more columns. The primary key must have a unique value for each row of the table.
The primary key is implemented directly on the data tree, which means there is no separate primary key tree. There is no ROWID or anything similar. The unique identification of a record is the primary key (for multiple keys, this is the combination of fields that are defined as the primary key).
