Craig L Russell commented on JDO-650: ------------------------------------- We have three choices to implement this functionality : a) expr ? exprT : exprF b) IF(...) ELSE... c) SQL syntax The a syntax is Java. The b syntax is "very close to" Java but there are some cases where you can't simply copy and paste JDOQL into a Java program. So this would just be one more case. The c syntax is not very close to Java. I withdraw my objection to use of syntax b. As Andy says, implementing syntax a can be done later if we choose. > 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 3.2 > > > 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. -- This message was sent by Atlassian JIRA (v6.2#6252)
