> Escape character in JPQL/SQL with parameter substitution generates incorrect
> SQL. E.g.
> "SELECT 'TRUE' AS VAL FROM DUAL WHERE '\\' = ?"
> or
> "SELECT * FROM ( SELECT FOLDER_ID, SYS_CONNECT_BY_PATH(NAME,'\\') AS PATH
> FROM PROJECT_FOLDER START WITH PARENT_ID IS NULL CONNECT BY PRIOR FOLDER_ID =
> PARENT_ID ) WHERE PATH LIKE ?"
> the '\\' will be transformed to '' and causes SQLException when send to the
> db server.
