Michael Bouschen commented on JDO-650:
--------------------------------------
I will fix 1. and 2. soon.
About the second positive test using a filter "IF (this.department.name ==
'Development') this.salary > 15000 ELSE this.salary > 25000":
It might be supported using the latest derby version. The derby doc
http://wiki.apache.org/db-derby/SQLvsDerbyFeatures says, "Extended CASE
expression" is supported from version 10.11.
However, I agree we should restrict the if-expression such that it is supported
by more databases. So I will change the second positive test.
What is the right name for the supported expressions in the then clause and the
else clause? I found 'scalar expression' and 'value expression'. But I could
not find a good definition for the two. Any suggestion?
> 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.
