 NHibernate 2.1.0 released.

 

Among numerous bug fixes, it includes an important feature: GroupBy projection.

 

Projections are similar to the expressions in SELECT statement of SQL. So if we have the following statement:

 

SELECT AVERAGE(SALARY) FROM EMPLOYEES GROUP BY JOB_TITLE

 

We will use a projection to calculate an average salary for every job title.

 

The framework can be downloaded from http://sourceforge.net/projects/nhibernate/files/NHibernate/NHibernate-2.0.1.GA-bin.zip/download
