Hi, We are having 3 tables; 1. persons <-- Base table and no data will be inserted in this table. 2. Person1 <-- Inherited table from persons all data will be inserted in this table. 3. PersonalInfo <-- which is storing all personal information of the persons and is having the foreign key relationship with the persons table. When we try to insert the data in the personalInfo table it is throwing the error stating the primary key does not contain the given value. But, if I try to select from the persons table it is showing the records from its inherited tables as well. Can anybody tell me what might be the problem here? Or else any help regarding the same will be of very much help. Following is the table structure; --------------------------------------------------------------------- Create Table persons ( name varchar, age int, dob varchar, constraint pKey primary key(name) ); create table person1 ( ) inherits(persons); Create table personalInfo ( name varchar, contact_id int, contact_addr varchar, constraint cKey primary key(contact_id), constraint fKey foreign key(name) references persons(name) ); -------------------------------------------------------------------------------------------------- Thanks In Advance, Ramachandra B.S.
