Resolution: Fixed
> Support for conditional operator ? : in JDOQL
> ---------------------------------------------
>
> Key: JDO-650
> URL: https://issues.apache.org/jira/browse/JDO-650
> Project: JDO
> Issue Type: New Feature
> Components: specification, tck
> Affects Versions: JDO 2 maintenance release 2 (2.2)
> Reporter: Michael Bouschen
> Assignee: Michael Bouschen
> Fix For: JDO 3.1
>
>
> JDOQL should support the Java conditional operator ? :, e.g. salary >= 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.
