Paul Benedict commented on HHH-2576:
------------------------------------
I wrote a patch and will upload it soon. This is how I have approached the issue, and am
sharing my philosophy early to receive any feedback. All Hibernate properties will become
available to SQL parsing. They are under the alias "hibernate" such as:
SELECT * FROM {hibernate.default_schema}.table
SELECT * FROM table FETCH FIRST {hibernate.default_batch_fetch_size} ROWS ONLY
I gave two special considerations "hibernate.default_schema" and
"hibernate.default_catalog". If these property names actually end in a dot, I
include the dot at the end, which will facilitate allowing fully-qualified objects being
optional if these properties are not specified.
This requires a default schema otherwise the SQL is invalid:
SELECT * FROM {hibernate.default_schema}.table
This allows the schema to be totally optional:
SELECT * FROM {hibernate.default_schema.}table
Allow native-sql to have placeholders for default schema and catalog

Key: HHH-2576
URL:
http://opensource.atlassian.com/projects/hibernate/browse/HHH-2576
Project: Hibernate Core
Issue Type: Improvement
Components: query-sql
Affects Versions: 3.2.3
Reporter: Max Rydahl Andersen
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.
