Hi to all: I have a question. PostgreSQL is Object-Relational DBMS . Can I progam Object-Oriented
Language for PostgreSQL?
Example: I create two tables: create table Address( street char(20),
city char(20), province char(20) );
create table students( no int4, name
char(8), address Address, ) insert into Address values
('ZHONG-SHAN','TAIPEI','TAIWAN');
I find the Address record's oid: => select oid from Address where province='TAIWAN';
oid -------- 28672 Then, I
inserta record to students table: => insert into students values (8852,'John',28672::Address);
Finally, I select the record about the student's province depend on oid: =>select no,name,address.province
fromstudents;
BUT PostgreSQL's message is error,why?
Thank you..... Frank
