COMPUTED BY fields or equivalent? - Mailing list pgsql-novice

Hi all,


I use Interbase (starting on PostgreSQL) which has a concept of

CREATE TABLE My_Table
(
  First_Name VARCHAR(15),
  Last_Name  VARCHAR(15),
  Full_Name  VARCHAR(30) COMPUTED BY(First_Name || ' ' || Last_Name)
}

Full_Name is now a read only field in My_Table.


Is there an equivalent in PostgreSQL.

I would also be interested in hearing if this concept exists in other
RDBMS's.

TIA.


Paul...
