Craig L Russell commented on JDO-650:
-------------------------------------

Is there any support for this in DataNucleus? If not, we should remove it from 3.1.

> JDOQL should support the Java conditional operator ? :, e.g. salay >= 1000.0 ? salary : salary * 1.1
> The conditional operator can be mapped to the CASE-expression in SQL: CASE WHEN condition THEN thenExpr ELSE elseExpr END. Are there any issues with non-SQL datastores when supporting the conditional operator? 
> Another question: which part of a JDOQL query can include a conditional expression? I propose the query filter, the having clause and the result specification.
