A distinct type is a user-defined data type that shares its internal representation with a built-in data type. The built-in data type is the source type. The name of a distinct type is qualified with a schema name. A distinct type is subject to the same restrictions as its source type.
Distinct type is a separate and incompatible data type because it does not automatically inherit the functions and operations of its source type. Only the functions and operators that are explicitly defined on a distinct type can be applied to it. When you select distinct types from the Investigator, CA Chorus displays cross-reference information for all user-defined data types.
