EJBQL Schema

The Jakarta Enterprise Beans, EJB-QL tests perform queries against a CMP 2.0 abstract persistence model that you deploy before you start the test runs.

Section 9.3.5, "EJB QL and SQL," in the EJB 3.1 Specification (http://jcp.org/en/jsr/detail?id=318) contains a sample mapping that shows how the Jakarta Platform, Enterprise Edition CI translates EJB QL to SQL, which helps to clarify the EJB QL semantics.

This appendix includes information about the following topics:
