[JIRA] (HHH-16505) interpretation of "bare" alias reference in HQL

by Gavin King (JIRA)

Gavin King ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) *created* an issue Hibernate ORM ( https://hibernate.atlassian.net/browse/HHH?atlOrigin=eyJpIjoiNzM4N2VhZTk3... ) / Bug ( https://hibernate.atlassian.net/browse/HHH-16505?atlOrigin=eyJpIjoiNzM4N2... ) HHH-16505 ( https://hibernate.atlassian.net/browse/HHH-16505?atlOrigin=eyJpIjoiNzM4N2... ) interpretation of "bare" alias reference in HQL ( https://hibernate.atlassian.net/browse/HHH-16505?atlOrigin=eyJpIjoiNzM4N2... ) Issue Type: Bug Affects Versions: 6.2.1 Assignee: Unassigned Components: query-hql Created: 24/Apr/2023 03:43 AM Priority: Major Reporter: Gavin King ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) So here’s a very interesting one that came up here: https://stackoverflow.com/questions/76073151/incorrect-sql-where-clause-g... Please ignore the actual query that the user displays, as you can see in my answer, it’s not a reasonable query to write. Instead just focus on the change in behavior. Given the query: SELECT book FROM Book book LEFT JOIN book.author a WHERE a is not null We optimize this to the SQL: select b1_0.id, b1_0.author_id, b1_0.publishingHouse_id, b1_0.title from Book b1_0 where b1_0.author_id is not null which is frankly pretty awesome. But now consider this variation: SELECT book FROM Book book LEFT JOIN book.author a WITH a.alive = true WHERE a is not null Now the generated SQL is: select b1_0.id, b1_0.author_id, b1_0.publishingHouse_id, b1_0.title from Book b1_0 left join Author a1_0 on a1_0.id=b1_0.author_id and a1_0.alive= true where b1_0.author_id is not null and, after reflection, I’m inclined to agree with the user that this is not quite correct. I think they’re probably right to say that a is not null should translate to {{a1_0.id is not null}}in this particular case.
