[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-2576) Allow native-sql to have placeholders for default schema and catalog

[Steve Ebersole (JIRA)]

    [ http://opensource.atlassian.com/projects/hibernate/browse/HHH-2576?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=34211#action_34211 ] 

Steve Ebersole commented on HHH-2576:
-------------------------------------

I would like to chime in about something else I plan on adding because it impacts here.  Eventually I'd like to be able to allow native-sql queries to use the function registry.  Also I'd like to see an explicit alias notation.

The reason I bring these up is that they all use {} as delimiters.  We need to consider adding some form of distinction to these so that we know what is being referenced.  For example, for functions I had considered {fn: } as distinct delimiter; so {fn:current_timestamp} for example.

Paul, I really like everything else you planned.

> we shold consider allowing something like:
> <sql-query name="queryName" callable="true">
> { call ${default_schema}.storedProcName() }
> </sql-query>
> similar for normal SQL queries too.
> <sql-query name="queryName">
> select * from ${default_schema}.CUSTOMER x where ...
> </sql-query>
> Maybe ${catalogschema} should be allowed to which would be the full prefix needed dependent on the dialect and would free one from having both catalog and schema + poper seperators in there.
