--------------------------------------
Summary: Entity read is not working due to normalization in
JPAQueryBuilder
Key: OLINGO-1147
URL: https://issues.apache.org/jira/browse/OLINGO-1147
Project: Olingo
Issue Type: Bug
Components: odata2-core
Affects Versions: V2 2.0.8
Reporter: Daniel Horvath
Priority: Blocker
Hello Colleagues,
We have found a bug in JPAQueryBuilder. In version 2.0.7 it is working fine but
in version 2.0.8 where the normalizeMembers() method is added it fails on
certain queries.
The error happens in line 180: {color:red}return
em.createQuery(normalizeMembers(jpqlStatement.toString()));{color}
The query before normalisation:
*SELECT E1 FROM Entity E1 WHERE E1.id = 'ENTITY_NAME.1.2'*
After the normalisation the query looks like this (an invalid query):
*SELECT DISTINCT E1 FROM Entity E1 JOIN 'ENTITY_NAME.1 R1 WHERE E1.id = R1.2'*
The regular expression finds this query as it should be normalised because of
the id part ('ENTITY_NAME.1.2'). As we found out, this is caused by the point
characters in the id field. It should not be found by the reg. exp. because
this is inside of apostrophes.
If you have further questions, please contact me.
Best regards,
Daniel
