Question

I have recently had performance problem with Nhibernate generated SQL as described in

Nhibernate generate plain sql query instead of execution statement

I also found a link describing similar experience from the one and only Jeff Atwood at

Does anyone know if there is anyway to add an “Optimize Uknown” option to Nhibernate?

Answer 1

• you could look into extending the MsSqlDialect or
• implement IConnectionProvider to inject your own commandwrapper which adds the hint when ExecuteReader() is called
