Craig L Russell commented on JDO-650:
-------------------------------------
Proposed specification update for Chapter 14:
If-expressions are allowed in the filter. If-expressions have the form if
(expressionB) expression1 else expression2. See Appendix B3 for details. The
expressionB must be a boolean expression.
If-expressions are allowed in the result. If-expressions have the form if
(expressionB) expression1 else expression2. See Appendix B3 for details. The
expressionB must be a boolean expression.
> 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.
