Subject [jira] Updated: (OPENJPA-1115) Finish support for delimited identifiers
Date Fri, 02 Oct 2009 17:13:23 GMT

     [ https://issues.apache.org/jira/browse/OPENJPA-1115?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Dianne Richards updated OPENJPA-1115:
-------------------------------------

    Attachment: auto_delim_id_patch.txt

This patch contains the support for auto delimiting identifiers - delimiting based on the
<delimited-identifiers> element being specified in the mapping file. 

Some exceptions:

1. The catalog elements are not delimited yet since catalog is not currently supported by
openjpa.

2. The columnDefinition elements are not delimited yet since there is some complication involved.
If a VARCHAR or other pre-defined column definition is delimited, the database rejects it.
Presumably, delimiting will only work for user defined column definitions. This will take
some time to work out and test.

3. There is some temporary code to work around a problem that occurs when a column name or
schema name or sequence name is read from the database to compare with the current request.
If they had been originally delimited, this is not known. The temporary solution works, but
is limited and not good. A new scheme will be implemented at a later time (hopefully soon).
