當(dāng)你需要在純C語(yǔ)言的應(yīng)用程序中訪問(wèn) MySQL 表中的數(shù)據(jù)時(shí)，是非常繁瑣的事情，而該框架可以幫你大量的簡(jiǎn)化編碼的工作，該框架采用 Python 開(kāi)發(fā)，適用于 C 語(yǔ)言程序。

示例代碼：

#include

#include

#include

#include

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);

}
