Hello everybody,
When studying the issue NH-1508 <http://jira.nhibernate.org/browse/NH-1508>,
I realized that MultiQuery is coupled to Hql(Sql is not possible). Fabio
told me to throw NotSupportedException temporarily, just to let the user
know about the situation.
The discussion between Fabio and me brought some ideas in my mind.
Let me tell what I have in my mind.
1. Define an interface INHQuery (a better name would be IQuery but it is
used for Hql) which will be base for IQuery and ICriteria, and in the future
Linq Queries. Can be either a marker interface or a set of common methods
such as cacheable etc. This part is optional)
2. Define a Batcher class(I need to study NH more to come up with full
declaration) and an interface IBatchQueryAppender<T> where T:INhQuery
The batcher will accept any INhQuery as long as its Appender is defined.
It will do the work to append the query to the batch.
This way, different querying methods can be used in the same batch.
This implementation will make MultiQuery and MultiCriteria obselete and
current implementations for those will redirect method calls to INhQuery in
order to prevent breaking changes.
This is my initial thoughts about the issue. Comments are welcome.
Cheers!
