注意
下一版本的 Microsoft SQL Server 将删除该功能。请不要在新的开发工作中使用该功能，并尽快修改当前还在使用该功能的应用程序。

Enumerates values for the LockType parameter of the LockObject method, implemented by most objects in the Decision Support Objects (DSO) library.

Constant	Description
olapLockExtendedRead	The object's properties can be read by other applications, but they cannot be changed or processed. This lock is used to prevent processing of dependent objects of an object that is being processed, such as dimensions that are shared by multiple cubes. Multiple olapLockExtendedRead locks can be applied to an object by multiple applications. However, no application can lock the object for processing or updating until all olapLockExtendedRead locks have been released.
olapLockProcess	The object's Process method can be initiated, and other applications can read the object's properties only until the lock is released. Only one olapLockProcess lock can be applied to an object at a time, and other applications can only apply olapLockRead locks while the olapLockProcess lock is in place.
olapLockRead	The properties of the object can be read from the repository and cannot be changed by another application until the lock is released. Other applications can issue olapLockRead, olapLockExtendedRead, and olapLockProcess locks, but not olapLockWrite locks, while the initial olapLockRead lock is in place.
olapLockWrite	The properties of the object can be modified in the repository using the Update method, and they are not available to other applications for any use until the lock is released. No other locks of any type can be applied to the object until the olapLockWrite lock is released.
