Issue Type: Bug Affects Versions: 6.2.3 Assignee: Unassigned Components: query-hql Created: 22/May/2023 12:49 PM Priority: Major Reporter: Piotr Przybylski ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... )
Same as https://hibernate.atlassian.net/browse/HHH-16241 , but for entity keys, so I will be reusing most of that issue’s contents (I didn’t test inserts, but I suppose they may be also broken).
The model has java.time.YearMonth attributes being mapped to integers on the DB (MariaDB):
@Convert(converter = YearMonthConverter.class)
@Column(name = "month" , nullable = false )
@Id
private YearMonth reportMonth;
Converter class:
public class YearMonthConverter implements AttributeConverter<YearMonth, Integer > {
@Override
public Integer convertToDatabaseColumn(YearMonth attribute) {
return attribute == null ? null : (attribute.getYear() * 100) + attribute.getMonth().getValue();
}
@Override
public YearMonth convertToEntityAttribute( Integer dbData) {
return dbData == null ? null : YearMonth.of(dbData / 100, dbData % 100);
}
}
Or use YearMonthDateType from Hypersistence Utils - the result is the same, i.e. building a query like
entityManager.createQuery( "SELECT MAX(de.yearMonthKey) FROM DemoEntity de" );
results in an exception:
org.hibernate.QueryException: Parameter 1 of function max() has type COMPARABLE, but argument is of type java.time.YearMonth
java.lang.IllegalArgumentException: org.hibernate.QueryException: Parameter 1 of function max() has type COMPARABLE, but argument is of type java.time.YearMonth
