clauses. https://bugs.eclipse.org/bugs/show_bug.cgi?id=350597 http://wiki.eclipse.org/EclipseLink/DesignDocs/312146 Code review: Andrei
(pending) Changes: - Added getTable(_expression_) to _expression_. - Moved getContainingDescriptor() up to DataExpression and chnaged code
to use it. - Added clonedExpression to ExpressionNormalizer to keep track of
identity. - Avoided duplicate normalization in reusable expressions. - Added FromAliasExpression to allow query key like usage on FROM clause
sub-selects. - Added FromSubSelectExpression to allow sub-selects in the FROM clause,
treated as TableExpressions. - Added SubSelectDatabaseTable to allow sub-selects to be treated as
table and printed in the FROM clause. - Added support for print SubSelectExpression in select clause. - Fixed issue of ReportQuery items using rebuild instead of copy. - Fixed mappingCriteria to take the base to ensure the mapping
_expression_ is twisted with the correct base. - Changed logging to log the category. - Fixed ReportQuery to copy having clause. - Fixed SchemaManager to reset database event listeners after creating
tables. - Added some @Overrides, some cleanup - Added sub-select FROM and SELECT clause tests to _expression_
subs-selects core test suite. - Got Stephen Mcritchie's infamous ParallelCorrelatedSubSelectsTest
working finally. - Changed _expression_ tests to unprepare in setup so they can be re-run. - Added JPA JPQL test for sub-select in the HAVING clause and sue with
comparison operators. |
