这是因为新的x行锁定和is表锁定是不兼容的。
The lock snapshot includes database summary information, application information and, of course, the lock information.
锁快照包含数据库摘要信息、应用程序信息，当然还有锁信息。
Since locks are used for interthread communication, it makes sense that taking out a lock would start a critical region and that releasing the lock would end the critical region.
既然锁定用于线程间通信，那么取消锁定会开启临界区，而释放锁定会结束临界区，这是行得通的。
The system detects that the P3 thread is holding a lock required by the P1 thread and elevates its priority to P1 until the lock is released.
如果系统检测到P 3线程正在持有一个P 1线程需要的锁，则会把P 3线程的优先级置为P1，直到它释放了锁。

当两个线程竞争同一个锁时，其中一个会得到锁，另一个不得不阻塞，直到锁可用。
Application 2 can establish an IX lock on the table and an X row lock, because the table lock IX is compatible to the IN table lock from A1.
应用程序2可以在表上建立一个IX锁定和一个x行锁定，因为表锁定ix兼容a1的in表锁定。

Lock - Number of locks held, deadlocks and lock waits escalations.
LOCK——保存的锁、死锁和锁等待升级的数目。
You can use AccessIntent to resolve the lock type and pass this lock type to the stored procedure, which then determines the correct SELECT statement syntax based on the lock type.
用户可以使用AccessIntent来解决锁定类型并将该死锁类型传送给存储过程，然后以锁定类型为基础，确定适当的SELECT语句语法。
Because the acquired lock does not persist across transaction boundaries, the import utility loses its IX table lock and must request another lock after each commit.
因为获得的锁不会跨事务边界存在，所以import工具将失去它的IX表锁，并且必须在每次提交之后请求另一个锁。
The load utility accomplishes this by requesting a super exclusive (Z) lock on the table and retaining this lock for the duration of the load operation (see Listing 4).
load工具实现这一点的方法是，请求目标表上的一个超级排他（Z）锁，并在加载操作期间一直持有这个锁（参阅清单4）。
Lock modes and lock object types are defined in the sqlmon.h include file, which will help you to decipher the numerical equivalents that the table function returns.
