Migrating OpenJPA to EclipseLink JPA: Query Hints
NOTE: Under Construction
Within a JPA application there is support for specifying query hints which define provider specific behaviour. These hints can be specified in annotations, within the ORM XML files, or within application code. The query hint names are strings and therefore do not typically force compile time dependencies on a particular provider but the values for these hints may introduce dependencies. The following sections outline OpenJPA query hints and their corresponding EclipseLink JPA features. If any query hint related migration information is missing or incomplete please log a documentation enhancement request referencing this page and provide details of your migration challenge.
Note: This migration information is based on the OpenJPA 1.2.1 documentation.
| OpenJPA Hint | Description | EclipseLink JPA Equivalent Functionality |
|---|---|---|
| openjpa.hint.OracleSelectHint | Specifies an Oracle specific query hint to be generated | eclipselink.sql.hint |
