    Resolution: Fixed

> Obsolete code in the tips 'n tricks
> -----------------------------------
>
>          Key: NH-780
>          URL: http://jira.nhibernate.org/browse/NH-780
>      Project: NHibernate
>         Type: Improvement
>   Components: Documentation
>     Versions: 1.2.0.Beta1
>     Reporter: Guy Mahieu
>     Priority: Trivial
>      Fix For: 1.2.0.CR1

>
> From the docs:
> <blockquote/>
> 11.13. Tips & Tricks
> You can count the number of query results without actually returning them:
> <code>
> IEnumerator countEn = session.Enumerable("select count(*) from ....").GetEnumerator();
> countEn.MoveNext();
> int count = (int) countEn.Current;
> </code>
> </blockquote>
> Other than looking like a workaround, this uses obsolete code (session.Enumerable); it might be better to change it to:
> <code>
> int count = (int) session.CreateQuery("select count(*) from ...").UniqueResult();
> </code>
