我收到下面的错误,说有堆栈溢出。发生这种情况是因为带有IN(id,id,id ... id)的sql语句有大量参数。有没有什么办法解决这一问题?这种情况发生在Eclipse的本地环境中。
JPA
@Query(value="SELECT p FROM PendingCourseRegistration p WHERE p.sisId IN ?1 AND p.testId = ?2")
List<PendingCourseRegistration> findPendingCourseRegistrationInSisIdsAndTestId(List<String> sisIds, Long testID);
错误

在使用Hibernate 4.3.1.Final的Grails项目(2.3.6)中,我们从未遇到过该错误,但由于查询缓冲区大小限制我们遇到了另一个错误:
由于您使用的是in (?, ..., ?)
,因此您列出的内容与列表中的项目一样多?,
,这意味着对于大型列表(50000表示),您可以编写100000个字符的查询,并且您可能有这个例外(这里有pgSQL驱动程序):
Foobar.executeQuery("select f from Foobar f where f.id in (:ids)",
[ids: 1L..100000L]); // Groovy way of creating a list of 100000 items.
错误:
SqlExceptionHelper:146 - An I/O error occured while sending to the backend.
SqlExceptionHelper:146 - This connection has been closed.
这就是为什么我认为你可能需要
将您的ID列表拆分为较小的列表(如500项左右)并手动合并结果,这比您正在使用的默认弹簧数据要做的更多。
将id列表存储到临时表中(使用JPA可能会证明这是一项痛苦的任务)。临时表将是(key,sids)的元组。你会生成一个临时密钥(对于会话),使用密钥批量插入id到该表,刷新以便hibernate将更改推送到数据库,使用子表使用该子查询(p.sidIds in (select sisIds from IdTable where key = ?1)
),删除数据从那张桌子。
虽然这是一项痛苦的任务,但它可能会提升表现。

我无法使用Hibernate 4.2.4复制此内容 你能提供你正在使用的Hibernate版本吗? 我建议的另一件事是尝试在&#34; antlr.BaseAST.toStringList()&#34;上设置一个断点。执行方法时,查看运行时变量和调用antlr方法的方法并导致循环
希望有所帮助
