当你需要在纯C语言的应用程序中访问 MySQL 表中的数据时，是非常繁琐的事情，而该框架可以帮你大量的简化编码的工作，该框架采用 Python 开发，适用于 C 语言程序。
示例代码#include <db.h> #include <stdio.h> #include <string.h> #include <time.h> int main (int argc, char **argv) { int ret; MYSQL global_mysql; MYSQL *m; db_ex_customer *cust1; db_ex_item *item1, *item2; mysql_init (& global_mysql); /* * connect to MySQL as usual */ m = mysql_real_connect (& global_mysql, "localhost", "root", "", "ex1", 3036, NULL, 0); /* * pass the MySQL connection to function, that initializes the "ORM" */ ret = db_init (& global_mysql); /* * the *__new method creates empty structure */ cust1 = db_ex_customer__new (); /* * setting the structure attribute with allocated string, * it will be freed during call of *__free method */ cust1->name = strdup ("alesak"); /* * this methods inserts the structure into according table. * If it has serial field, its value is reflected into structure */ ret = db_ex_customer__insert (cust1); item1 = db_ex_item__new (); item1->customer_id = cust1->id; item1->itemname = strdup ("simple orm"); ret = db_ex_item__insert (item1); item2 = db_ex_item__new (); item2->customer_id = cust1->id; item2->itemname = strdup ("advanced orm"); ret = db_ex_item__insert (item2); db_ex_customer__free (cust1); db_ex_item__free (item1); db_ex_item__free (item2); return (0); }
