ORACLE数据库得建表语句-ORACLE database built in Table statement

双向循环链表节点：数据域+指针域指针域：一个指针指向前一个同类型节点，另一个指针指向后一个同类型节点（1）设计节点struct db_node{int data;struct db_node * prev;struct db_node * next;};（2）创建空链表//创建了一个只有头节点的双向循环链表，返回头节点的地址struct db_node * create_db_list(void){struct db_node * phead = (struct db_node *)malloc(sizeof(struct db_node));if(phead == NULL)exit(-1);else{phead->next = phead;phead->prev = phead;}return phead;}（3）制造新节点//制造新节点，返回新节点的地址struct db_node * make_db_node(int value){struct db_node * pnew = (struct db_node *)malloc(sizeof(struct db_node));if(pnew == NULL)printf("malloc failed! ");else{pnew->data = value;pnew->next = NULL;pnew->prev = NULL;}return pnew;}（4）插入节点//把pnew指向的节点插入到头节点的前面，也就是整个链表的末尾bo
