本文整理了Java中org.hibernate.query.Query.iterate方法的一些代码示例，展示了Query.iterate的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Query.iterate方法的具体详情如下：
包路径：org.hibernate.query.Query
类名称：Query
方法名：iterate

Query.iterate介绍

[英]Return the query results as an Iterator. If the query contains multiple results pre row, the results are returned in an instance of Object[].

Entities returned as results are initialized on demand. The first SQL query returns identifiers only.
[中]以迭代器的形式返回查询结果。如果查询包含多个结果，则结果将在Object[]的实例中返回。
作为结果返回的实体按需初始化。第一个SQL查询只返回标识符。
