Inherited tables

Hello, I'm trying to inherit primary key constraint from a table. I'm using DS/UDO 9.14.UC4. The SQL code is something like this: CREATE TABLE Tables OF TYPE Tables_t (PRIMARY KEY (name)); CREATE TABLE CatTable OF TYPE CatTable_t UNDER Tables; where: 1. Tables_t is a row type having a field named "name" 2. CatTable_t is a sub-type of Tables_t Reading the documentation I supposed to have a primary key on the name field in the CatTable table too, but that doesn't happen!! I'm wrong or something in the server is wrong? Thanks in advance Best regards Lucio -- ( Lucio Benfante http://www.dei.unipd.it/~benfante ) Sent via Deja.com http://www.deja.com/ Share what you know.
