Data type code for SDO_GEOMETRY and other non built-in types

User_1U2TW

Hello, I can see data type code (integer value) of built-in types here (https://docs.oracle.com/en/database/oracle/oracle-database/19/sqlrf/Data-Types.html#GUID-7B72E154-677A-4342-A1EA-C74C1EA928E6)

How can I find the data type code for non built-in types such as SDO_GEOMETRY, MEDIA TYPES, ANYTYPE etc. ?

Is there any documentation available ? Or any query to see the types and code for non built-in types ?

Thanks
