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

------------------------------------------

Nice to see progress on this one (me being lazy not doing it sooner ;)

I tend to agree with Steve on not seeing the need for free access to hibernate properties. 
Sure, it could be "cool" to do - but it also just seem to be a very wide and open door
risking all kind of issues depending on what the values actually are; accidentally sql injection
etc. 

Without a good use case I see more danger in that than value.

Access to functions sound good, but not sure a basic {h-fn xxx} is enough - doesn't it need to receive parameters to expand/work correctly ?

Leaving the initial feature last, then {h-catalog.} is needed too; or at least some {h-catalog-schema.} option that would generate the fully qualified name needed databases that need both.

> 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.
