Milosz Tylenda reopened OPENJPA-975:
------------------------------------


I am afraid we have the problem with the patch applied to trunk.

1. Building the manual fails with message: 'The id 
"DBDictionary.SearchStringEscape" already exists in this document.' This is 
because of property description being doubled - it exists in generic database 
section and in Oracle. Should be in generic only.

2. The DBDictionary.RequiresSearchStringEscapeForLike should be rather moved 
from Oracle section to generic one as this is a DBDictionary property.

I did not check the health of branches.


> Oracle needs ability to not have an escape character for search strings.

> 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.
