最简单的ecpg程序例子

#include <stdlib.h>    
    
exec sql include sqlca;    
    
main() {    
    
    exec sql connect to 'enterprisedb@localhost:9999' user 'enterprisedb' identified by 'enterprisedb';
    
    exec sql BEGIN TRANSACTION;
    
    exec sql UPDATE a5 SET id=100 WHERE id=88;
    
    exec sql COMMIT;
    
    exec sql disconnect all;
    
    return 0;
    
}    

这里面，用的是连接 enterprisedb 的PPAS的例子
