Effect
Defines 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 information specified for the primary key can only be omitted for standard tables. The primary table key is then defined automatically as a non-unique standard key. -
Multiple secondary
table keys with
secondary_key1,secondary_key2,...
Secondary keys are optional keys for all table categories. If no secondary key is specified, the internal table has only one primary key.
Example
Declares a hashed table with a unique primary key plus two non-unique secondary
sorted keys, cityfrom_to and airp_from_to.
DATA spfli_tab TYPE HASHED TABLE OF spfli
WITH UNIQUE KEY carrid connid
WITH NON-UNIQUE SORTED KEY cityfrom_to COMPONENTS cityfrom cityto
WITH NON-UNIQUE SORTED KEY airp_from_to COMPONENTS airpfrom airpto.
