DslQuery

Representation of a query (conceptually, a SQL SELECT statement more or less). If attached to a persistent context, then can be used DslQuery#fetch() fetch 'ed. If not attached, can be used to build other queries (because it also implements the QueryDSL Expression interface.

Typically is built up using QueryDslSupport (in which case will be attached to a persistence context and can be fetched immediately if desired), or else using DetachedQueryFactory (in which case will not be attached, but can be used to build up other queries, eg as a subquery).
