[jira] [Updated] (JDO-650) Support for conditional operator ? : in
JDOQL
[ https://issues.apache.org/jira/browse/JDO-650?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Craig L Russell updated JDO-650:
--------------------------------
Description:
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.
