   First version QueryTests page (describing JDO TCK query test changes)

New Page:

= JDO TCK 1.1 Test Cases =

The current JDO TCK (as implemented in the tck11 sub-project) does not implement all the JDO
TCK assertions. For some of these assertions the unimpl_tests directory of the Sun cvs repository
includes test classes where the test method need to be implemented. The spreadsheet assetions/Jdo``Tck``Assertions``Table.sxc
lists all the assertions.

Here are the unimpl tests for package org.apache.jdo.tck.query:

||Assertion No.||Class||Comment||
||A5.4.3-9  ||Queries``Of``Instances``With``Nondatstore``Identity||Not testable with JDO RI||

||A14.6.5-2 ||Scope``Of``Variable``Not``Named``In``Contains``Clause``And``No``Extent||JDO

Here are the unimpl tests for package org.apache.jdo.tck.query.operators:

||Assertion No.||Class||Comment||
||A14.6.2-20||Boolean``Logical``AND||prio 2||
||A14.6.2-21||Conditional``AND||prio 1||
||A14.6.2-22||Boolean``Logical``OR||prio 2||

||A14.6.2-34||Null``Collections``And``Is``Empty||prio 3||
||A14.6.2-35||Null``Collections``And``Contains``Method||prio 3||

These are JDO 1.0 assertions w/o test class in the unimpl_tests directory.

||Assertion No.||Comment||
||N14.4-5||Multiple identical imports||
||N14.6-15||Query.setXXX method repalce previous values||
||N14.6.1-7||Changing query resukt collection fails||

= JDO TCK 2.0 Test Cases =

JDO 2.0 extends the Query API and the Query language JDOQL. 

== Query API ==

The spreadsheet lists the following assertions for JDK TCK 2.0 that make sure a JDO 2.0 implementation
supports the new Query API methods:

||Assertion No.||Comment||
||N2-14.6-16||Query.setResult||
||N2-14.6-17||Query.setGrouping||
||N2-14.6-18||Query.setUnique||
||N2-14.6-19||Query.setResultClass||
||N2-14.6-20||Query.setRange||
||N2-14.6-18||Query.setUnique||

JDO adds the following methods to the Query API, but there are no assertions for these methods
yet:
 * void setUnmodifiable()
 * boolean isUnmodifiable()
 * void setExtensions(Map extensions)
 * void addExtension(String key, Object value)

== JDOQL 2.0 ==

JDO 2.0 extensions of the JDO query language JDOQL:

 * Single string JDOQL
 * Result specification
   * Projections of fields and relationships
   * One or more result expressions
   * Distinct results
   * Unique query result
   * Default result class for one or more result expressions
   * User defined result class
   * Naming of result expressions
 * Aggregate functions MIN, MAX, SUM, AVG, and COUNT
 * Grouping of query result
   * One or more grouing expressions
   * Having clause
 * New methods in Query filters:
   * Map support: get(Object), containsKey(Object), containsValue(Object), isEmpty()
   * Additional string methods: toLowerCase(), toUpperCase(), indexOf(String), indexOf(String,
int), matches(String), substring(int), substring(int, int)
   * Support for other methods: Math.abs(numeric), Math.sqrt(numeric), JDOHelper.getObjectId(Object)
 * New operators %(modulo) and instanceof
 * Support for implicit parameters
 * Support for implicit variables
 * Deletion by query
