DataNucleus 4.1.0 发布,此版本修复了一些Bug,并新增了一些功能。

Bug 修复

  • [ NUCCORE-1311 ] - JPQL "[NOT] IN" not compiled correctly when we have parameter yet value type not yet known

  • [ NUCJPA-308 ] - CriteriaBuilder.in always tries to create "(val == collVal1 || val == collVal2 || ...) but should use IN if single value specified to allow for Collection parameter

  • [ NUCRDBMS-893 ] - FROM joins should process first part of the join expression and take the table for that as one side of the join

新增功能

  • [ NUCCORE-1308 ] - Support Java generic TypeVariable in 1-1/N-1 relations

  • [ NUCCORE-1309 ] - Support Java generic TypeVariable in 1-N/M-N relations

  • [ NUCCORE-1312 ] - Support JPQL with RIGHT OUTER JOIN

  • [ NUCRDBMS-892 ] - Support JPQL with RIGHT OUTER JOIN

性能提升

  • [ NUCCORE-1313 ] - Support JPQL FROM "ON" clauses that are other than DyadicExpression

  • [ NUCCORE-1314 ] - If annotation specified on field and method then take as field and use method annotations as if on field

  • [ NUCJPA-307 ] - Criteria API usage currently requires something to be selected (using select/multiSelect) whereas could default to candidate

  • [ NUCRDBMS-894 ] - Query of Collection.contains where the element is of an invalid type should create query with 1=0 rather than throw exception

  • [ NUCRDBMS-895 ] - Support JPQL "COALESCE"/"NULLIF" with non-numeric arguments

任务

  • [ NUCAPIJDO-91 ] -Support typesafe query StringExpression.add(...)

  • [ NUCJPA-306 ] - Change "datanucleus.rdbms.allowColumnReuse" default to "true" for JPA usage

  • [ NUCRDBMS-890 ] - JPQL : Support use of MEMBER OF on Map (and interpret as "Map.containsValue")

  • [ NUCRDBMS-891 ] - Support query joins that join to EmbeddedId to provide access to the fields

  • [ NUCRDBMS-896 ] - JDOQL : support CharacterLiteral.toUpperCase/toLowerCase methods
