mysql_init(&mysql);
if (mysql_real_connect(&mysql, "localhost", "root", "Susake", "Susake", 0, NULL, 0))

        printf("数据库连接成功\n");
mysql_query(&mysql, "insert into Ran(a, b) values(1, 2);");
mysql_real_query(&mysql, "select *from Ran;", strlen("select *from Ran;"));
res = mysql_store_result(&mysql);
while (row = mysql_fetch_row(res))

        printf("%s %s\n", row[0], row[1]);
