Hi, I am using Red Hat 6.1 + PostgreSQL 7.0.3. All of
my
applications are developed by C and ECPG. I would
like to know how to execute a C program by Trigger,for
example:
1. I have a program my_c_program.c shuch as:
#include <stdio.h>
main()
{ printf("Hello World !\n");
}
2. I create a table foo by following command
CREATE TABLE foo(x int4);
3. create a trigger foo_trig :
create trigger foo_trig after update on foo for each row execute procedure sql_c(); 4. I don't know how to design
sql_c(),can anyone give a small plpsql program that can execute my_c_program?
regards, S.F. Lee
