Subject [jira] [Created] (OPENJPA-2376) Escape character in JPQL with parameter substitution generates incorrect SQL
Date Wed, 24 Apr 2013 16:41:17 GMT
Albert Lee created OPENJPA-2376:
-----------------------------------

             Summary: Escape character in JPQL with parameter substitution generates incorrect
SQL
                 Key: OPENJPA-2376
                 URL: https://issues.apache.org/jira/browse/OPENJPA-2376
             Project: OpenJPA
          Issue Type: Bug
          Components: jdbc
    Affects Versions: 2.2.1, 2.1.1, 2.2.2, 2.2.1.1
            Reporter: Albert Lee
            Assignee: Albert Lee


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.
