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.
