Apart from its core :SQL-92 functionality, IUS offers additional features including : : .Row types (which can be used to define "record type" columns or tables) :'Collection types (set, multiset and list) 'Distinct and opaque types :(which can be used to create user-defined types) 'User defined functions :(on built-in or user-defined types) 'Table-level inheritance 'The Virtual :Table Interface and Virtual Index Interface (which can be used to add :custom storage and access methods) All these features of IUS are so usefull I can hardly wait to get my hands on it and start using it. I am only waiting for it to be available at a reasonably priced platform (Linux would be ideal with SCO Unix and Windows NT as distant second choices). At the user conference (last year and this year) Stonebreaker was also talking about reference types for columns. That is a column could contain a reference to a row in some table (a pointer). I can't find anything about this in the IUS 9.1 manuals (downloaded from the Informix web pages). Such a datatype would seem to be very usefull even though C.J.Date would have (and reportadly have) balked at such a feature. Does anyone know if reference column types are currently available or are planned for some future version of IUS?
