Definition
An alias name for the primary key of a table type can be defined as optional.
Use
Dependencies
An alias name for the primary key may only be defined for a table type that does not have generic primary properties, is not a STANDARD table and does not possess a standard key.
Therefore the creation of an ALIAS is only possible if the following apply:
- the table type is HASHED TABLE or SORTED TABLE
- the key definition is "row type" or "user specified"
- the uniqueness must be specified or be automatically correctable (that means UNIQUE for HASHED and NON-UNIQUE/UNIQUE for SORTED)
