      org.hibernate.dialect.TimesTenDialect

A SQL dialect for TimesTen 5.1. Known limitations: joined-subclass support because of no CASE support in TimesTen No support for subqueries that includes aggregation - size() in HQL not supported - user queries that does subqueries with aggregation No CLOB/BLOB support No cascade delete support. No Calendar support No support for updating primary keys.
