Subject [jira] Created: (JDO-650) Support for conditional operator ? : in JDOQL
Date Sun, 29 Nov 2009 20:51:20 GMT
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, tck2
    Affects Versions: JDO 2 maintenance release 2
            Reporter: Michael Bouschen
            Assignee: Michael Bouschen


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.
