我想知道，通过上下文从数据库获取数据，entry的当前值和原始值，和数据库的当前值和原始值一样还是，entry的当前值和原始值都是数据库的当前值？

按照下面的描述，应该是第二种情况，可是我还是想确定一下

When you use the ApplyCurrentValues method in the disconnected scenario, you
query for the current data in the database and then apply your changes. This means
the original values of the entry are those read by the database. When you call Apply-
CurrentValues, the current values in the entry are modified but the original values
(which are those read from the database) aren’t.
Here a big problem arises. When you invoke SaveChanges, the generated WHERE
clause uses the original value of the Version property, which holds the current database
value. The consequence is that the database’s current value is used in the WHERE
clause, causing the data to be modified even if it has since been changed by someone
else.
