[eclipselink-dev] SVN Commit: Bug#251594 Add missing query hints

SVN Commit: Bug#251594 Add missing query hints


Split work into two phases, this is the first phase (easy ones).



Added the following hints:

- maintain-cache

- prepare

- jdbc.cache-statement

- sql.hint

- flush

- jdbc.native-connection

- cursor

- cursor.initial-size


- cursor.scrollable

- cursor.size-sql


- fetch-group.attribute

- fetch-group.default

- cache-usage +support modify queries

- exclusive-connection

- inheritance.outer-join



- jdbc.first-result


Also fixed,

- native queries are always created as DataRead, and not all properties copied

over if switched to DataModify, need to use copyFromQuery(), current code will

also fail for existing NamedStoredProcedureQuery.

- getSingleResult should allow returning of Cursors and Maps, (and Sets)

- need to add getResultCursor()


And improved all hint comments.


Code Review: Andrei (pending)
