[eclipselink-dev] Bug 300512 - Add FUNCTION support to extended JPQL

["Andrei Ilitchev" <andrei.ilitchev@xxxxxxxxxx>]

https://bugs.eclipse.org/bugs/show_bug.cgi?id=300512

 

This patch is prototype 3 patch + some clean up and tests added.
- defines a new key word FUNC to be used to define new JPQL functions;
- see the new class FuncNode for examples of custom functions:
NVL, TO_NUMBER, TO_DATE and four JGeometry (SDO) functions;
- added more type checking for standard jpa 2.0 functions;
- fixed a couple of adjacent bugs:
Bug 246598 - Unable to parse TRIM in JPA NamedQuery;
Bug 303540 - JPQL: query fails to compile if variable found only in function
parameters.

 

Please send any feedback you may have.

 

Thanks,

 

Andrei
