[jira] [Commented] (OAK-155) Query: limited support for the deprecated JCR 1.0 query language Query.SQL

["Julian Reschke (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/OAK-155?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13402980#comment-13402980 ] 

Julian Reschke commented on OAK-155:
------------------------------------

Sounds right to me. As far as I recall, if we can map XPath as specified in JCR 1.0, then we should also be able to map SQL (as per JCR 1.0).

Reminder: given a different query parser we may end up with differences in how invalid queries are handled; Jackrabbit IMHO is very forgiving when seeing things it doesn't understand.

> Existing applications (as well as the TCK) use the JCR 1.0 query language
> "sql". As far as I know, there are only few differences between JCR 1.0 SQL and JCR 2.0 SQL-2. To make old applications work with Oak, I suggest we provide support JCR 1.0 SQL as well. An additional advantage is that more of the existing TCK tests can be run.
> I currently don't know if the full JCR 1.0 SQL syntax can be supported (similar to XPath); if we find supporting certain features is too complicated we will document those limitations instead.
