B.J. Reed updated OPENJPA-975:
------------------------------

    Attachment: OPENJPA-975b.patch

Thanks Milosz for the review.

I had noticed all the "required" properties a few days ago and there was some subtle difference
on the name that I landed on.....but that logic totally escapes me now, so I've renamed to
requiresSearchStringEscapeForLike - also want to make it as obvious as possible that it works
with the  "SearchStringEscape" property.

I have it on my list of TODO's to update the documentation.

Have opened up http://issues.apache.org/jira/browse/OPENJPA-976 to do more investigation about
which DB's prefer the search string escape.  At this time my knowledge of all the DB's is
rather limited, but I'll be happy to do that research.

> Oracle application has a JPQL query that attempts to set a parameter to '\'. '\' is not
a reserved character with Oracle and the query will work if you execute it "normally" with
JDBC.
> OpenJPA automatically adds ESCAPE ('\') to every search SQL query.  As a result the \
is interpreted as an escape indicator and the SQL will not execute as expected.
