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

[Paul Benedict (JIRA)]

    [ http://opensource.atlassian.com/projects/hibernate/browse/HHH-2576?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=34290#action_34290 ] 

Paul Benedict commented on HHH-2576:
------------------------------------

>> I'm fine to entertain other delimiters. I just went with {fn: }...

Two issues arise:
1) The use of the colon requires mods to the parameter parser. 
2) {fn} is already in use as a JDBC escape syntax.

I would suggest {hibernate-fn xxx} for a function and {hibernate-prop xxx} for a key:
INSERT INTO {hibernate-prop hibernate.default_schema.}table (ts) VALUES ({hibernate-fn current_timestamp})

> 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.
