> 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.
