[hibernate-issues] [JIRA] (HHH-16216) @Query creates additional not null checks for Sybase

Marius K ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=70121%3... ) *created* an issue Hibernate ORM ( https://hibernate.atlassian.net/browse/HHH?atlOrigin=eyJpIjoiNTRkYzczMTcy... ) / Bug ( https://hibernate.atlassian.net/browse/HHH-16216?atlOrigin=eyJpIjoiNTRkYz... ) HHH-16216 ( https://hibernate.atlassian.net/browse/HHH-16216?atlOrigin=eyJpIjoiNTRkYz... ) @Query creates additional not null checks for Sybase ( https://hibernate.atlassian.net/browse/HHH-16216?atlOrigin=eyJpIjoiNTRkYz... ) Issue Type: Bug Affects Versions: 6.2.0.CR2, 6.1.7 Assignee: Unassigned Components: query-hql Created: 22/Feb/2023 01:00 AM Priority: Critical Reporter: Marius K ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=70121%3... ) I upgraded from Spring Boot 2.7 to 3.0, hence from Hibernate 5 to Hibernate 6 Unfortunately the @Query annotations in a JpaRepository suddenly add not null checks for all columns using Sybase. It works fine with h2 @Entity @Table(name = "MY_USER") @Getter @Setter @EqualsAndHashCode public class MyUser { @Id @Column(name = "MY_USER_ID", unique = true, nullable = false) private Integer myUserId; @Column(name = "FIRSTNAME") private String firstname; @Column(name = "LASTNAME") private boolean lastname; } and public interface MyUserRepository extends JpaRepository<MyUser, Integer> { @Query("select r from MyUser r where r.firstname = :firstname and r.lastname = :lastname") List<MyUser> getUser(@Param("firstname") String firstname, @Param("lastname") String lastname); } results in the query select m1_0.my_user_id,m1_0.firstname,m1_0.lastname from my_user m1_0 where m1_0.firstname=? and m1_0.lastname=? which is obviously fine. But when I switch to Sybase spring.datasource.url=xxx spring.datasource.username=xxx spring.datasource.password=xxx spring.datasource.driver-class-name=com.sybase.jdbc4.jdbc.SybDriver spring.jpa.database-platform=org.hibernate.dialect.SybaseASEDialect <dependency> <groupId>com.sybase</groupId> <artifactId>jconn4</artifactId> </dependency> the query is select m1_0.my_user_id,m1_0.firstname,m1_0.lastname from my_user m1_0 where m1_0.firstname=? and m1_0.firstname is not null and m1_0.lastname=? and m1_0.lastname is not null with additional null checks. This breaks my code as it is no longer possible to pass null to the parameters in the getUser ` method.
