有时，您需要一个简单的验证点，但是有时您需要条件语句，还有时您需要添加一个延迟或者循环。

Sometimes, you can get by with a simple verification point, but sometimes you need conditionals, and sometimes you need to add a delay or a loop.

这就是延迟加载，即尽可能长的延迟查询语句的执行。

This is lazy loading, or deferring the query as long as possible.

在多个查询语句的执行过程中需要保持数据库连接，否则会抛出一个延迟加载异常，这将导致数据出现问题。

Database connection needs to be maintained for the duration of the multiple query cycle else a lazy loading exception is thrown, resulting in inadequate use of resources.
