问题：
Can someone explain the implications of using with (nolock) on queries, when you should/shouldn't use it? 当你应该/不应该使用它时，有人可以解释使用with (nolock)对查询的影响吗？
For example, if you have a banking application with high transaction rates and a lot of data in certain tables, in what types of queries would nolock be okay? 例如，如果您的银行应用程序具有较高的事务率和某些表中的大量数据，那么哪些类型的查询可以解决？ Are there cases when you should always use it/never use it? 是否应该经常使用它/从不使用它？
