 ##### 3 临键锁(Next-Key Locks)
 
 有时候我们既想 `锁住某条记录` ,又想 阻止 其他事务在该记录前边的 间隙插入新记录 ,所以InnoDB就提 出了一种称之为 Next-Key Locks 的锁,官方的类型名称为: LOCK_ORDINARY ,我们也可以简称为 next-key锁 。Next-Key Locks是在存储引擎 innodb 、事务级别在 可重复读 的情况下使用的数据库锁, innodb默认的锁就是Next-Key locks。比如,我们把id值为8的那条记录加一个next-key锁的示意图如下:

 `next-key锁`的本质就是一个`记录锁`和一个`gap锁`的合体,它既能保护该条记录,又能阻止别的事务将新记录插入被保护记录前边的`间隙`。

 * **情景一**:对于聚簇索引记录来说,有一个 `trx_id` 隐藏列,该隐藏列记录着最后改动该记录的 `事务 id` 。那么如果在当前事务中新插入一条聚簇索引记录后,该记录的 trx_id 隐藏列代表的的就是 当前事务的 事务id ,如果其他事务此时想对该记录添加 S锁 或者 X锁 时,首先会看一下该记录的 trx_id 隐藏列代表的事务是否是当前的活跃事务,如果是的话,那么就帮助当前事务创建一个 X 锁 (也就是为当前事务创建一个锁结构, is_waiting 属性是 false ),然后自己进入等待状态 (也就是为自己也创建一个锁结构, is_waiting 属性是 true )。
 * **情景二**:对于二级索引记录来说,本身并没有 trx_id 隐藏列,但是在二级索引页面的 Page Header 部分有一个 `PAGE_MAX_TRX_ID` 属性,该属性代表对该页面做改动的最大的 `事务id` ,如 果 PAGE_MAX_TRX_ID 属性值小于当前最小的活跃 事务id ,那么说明对该页面做修改的事务都已 经提交了,否则就需要在页面中定位到对应的二级索引记录,然后回表找到它对应的聚簇索引记 录,然后再重复 情景一 的做法。

 在隔离级别为读已提交(Read Committed)时,一个事务中的每一次 SELECT 查询都会重新获取一次 Read View。

> 注意,此时同样的查询语句都会重新获取一次 Read View,这时如果 Read View 不同,就可能产生不可重复读或者幻读的情况。
 
 当隔离级别为可重复读的时候,就避免了不可重复读,这是因为一个事务只在第一次 SELECT 的时候会获取一次 Read View,而后面所有的 SELECT 都会复用这个 Read View,如下表所示:
