SELECT * FROM `ecs_order_info` WHERE
( ( `order_status` = 5 AND `shipping_status` = 2 ) OR `order_status` = 6 ) AND `user_id` = 1
上面标红的where查询语句在TP中的拼接如下：
SELECT * FROM `ecs_order_info` WHERE ( ( `order_status` = 5 AND `shipping_status` = 2 ) OR `order_status` = 6 ) AND `user_id` = 1上面标红的where查询语句在TP中的拼接如下： $o
创建与初始化：
int** graph = new int*[N + 1];
for (int i = 0; i < N + 1; i++) { graph[i] = new int[N + 1]; for (int j = 0; j < N + 1; j++) { graph[i][j] = 0; }}
删除：for (in
