Thread: ODBC 7.1
Greetings All, Is this the correct forum to discuss ODBC driver issues? I have a Linux/PostgreSQL server which has been upgraded to run 7.1 - the main reason was to be able to use the TOAST extensions. We have some documentation attached to fields which is up to 64kb. After upgrading the server I installed the current (7.1) ODBC driver for Win32. It now seems that concurrent table writes are limited? My write times are fairly slow. (significantly slower than 6.4/7.0) Some tables which are updated simultaneously - like sales and general ledger are not staying in synch. Any suggestions would be welcomed (including upgrades) -- Keith Gray Technical Development Manager Heart Consulting Services P/L mailto:keith@heart.com.au

hi all i have a table like this CREATE SEQUENCE seq_student_id INCREMENT 1 START 1; CREATE TABLE students ( student_id INT4 NOT NULL DEFAULT NEXTVAL('seq_student_id'), student_name text, student_address text, primary key(student_id) ) CREATE TABLE student_club ( student_id INT4 NOT NULL; club_id INT4, CONSTRAINT student_id_update FOREIGN KEY(student_id) REFERENCES students(student_id) ON UPDATE CASCADE ) my question is how i can make auto insert student_id on table student_club when i insert into table students example: INSERT INTO students(student_name) VALUES('Willy'); table STUDENT student_id | name | address --------------------------------- 1 | Willy | and on TABLE student_club student_id | club_id -------------------- 1 | i have trying with create rule and with check_foreign_key, but i haven't found solution. anyone can help me?

Are you ready to solve your problem using a trigger and 'plpgsql' function ?? .. then proceed .. trigger :) +++++++++++++++++++++++++++++++++++++++++++ CREATE TRIGGER trigger_student_club before INSERT OR UPDATE ON students FOR EACH ROW EXECUTE PROCEDURE ins_student_club_func(); +++++++++++++++++++++++++++++++++++++++++++ function :) +++++++++++++++++++++++++++++++++++++++++++ CREATE FUNCTION ins_student_club_func()RETURNS OPAQUEAS 'BEGIN INSERT INTO student_club(student_id) VALUES (new.student_id); return new; END;' LANGUAGE 'plpgsql'; +++++++++++++++++++++++++++++++++++++++++++ Hope it works. :) Regards, Bhuvaneswar.
