Nathan Xu ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) *updated* an issue Hibernate ORM ( https://hibernate.atlassian.net/browse/HHH?atlOrigin=eyJpIjoiNWZlMmFlMTFk... ) / Improvement ( https://hibernate.atlassian.net/browse/HHH-14133?atlOrigin=eyJpIjoiNWZlMm... ) HHH-14133 ( https://hibernate.atlassian.net/browse/HHH-14133?atlOrigin=eyJpIjoiNWZlMm... ) fix error in example code for 'second level cache' in user guide ( https://hibernate.atlassian.net/browse/HHH-14133?atlOrigin=eyJpIjoiNWZlMm... ) Change By: Nathan Xu ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) In the following example code for 'second level cache', there are obvious errors (redundant space chars char at the end of hint property name), which was is misleading and , confusing and definitively wrong. !Screen Shot 2020- 07 08 - 31 01 at 7. 11 33. 41 PM 27 AM.png| thumbnail width=100% !

[JIRA] (HHH-14134) Querying with "IS NOT EMPTY" jpql against a @OneToMany mappedBy collection is failing in mysql for Hibernate v. 5.4.11 and up

by Kean Erickson (JIRA)

Kean Erickson ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) *commented* on HHH-14134 ( https://hibernate.atlassian.net/browse/HHH-14134?atlOrigin=eyJpIjoiYjM4ZT... ) Re: Querying with "IS NOT EMPTY" jpql against a @OneToMany mappedBy collection is failing in mysql for Hibernate v. 5.4.11 and up ( https://hibernate.atlassian.net/browse/HHH-14134?atlOrigin=eyJpIjoiYjM4ZT... ) It looks like extra parentheses are added to the select columns corresponding to an “collection IS NOT EMPTY” check in JPQL, where the collection is a @OneToMany with mappedBy. Mysql doesn’t like these added parens. The query originally in 5.4.10 came out as > > > > select * from a where not (exists ( > select collection.a_id, collection.b_id from collection where a.id ( > http://a.id ) = collection.a_id)); > > But in 5.4.11 it resolves to > > > > select * from a where not (exists ( > select (collection.a_id, collection.b_id) from collection where a.id ( > http://a.id ) = collection.a_id)); > > ( https://hibernate.atlassian.net/browse/HHH-14134#add-comment?atlOrigin=ey... ) Add Comment ( https://hibernate.atlassian.net/browse/HHH-14134#add-comment?atlOrigin=ey... ) Get Jira notifications on your phone!
