Effect
Definition of the table keys in an internal table. The following can be defined:
-
A primary table key using
key.
Every internal table has a primary key. The primary key must be defined explicitly for sorted tables and hashed tables. The primary key specification can only be omitted for standard tables. The primary table key is then automatically defined as a non-unique standard key. -
Several secondary table
keys with
secondary_key1,secondary_key2,....
Specification of secondary keys is optional for all table types. If no secondary key is specified, the internal table has only one primary key.
