Fabio Maulo commented on NH-808:
--------------------------------

I don't understand..
		protected class CountQueryFunctionInfo : StandardSQLFunction
		{
			public CountQueryFunctionInfo() : base("count") { }
			public override IType ReturnType(IType columnType, IMapping mapping)
			{
				return NHibernateUtil.Int64;
			}
		}
It is Int64.
There is a different implementation (porting from H3.2) if a dialect use ClassicCountFunction (return type is Int32) but, until now no dialect use it.

Perhaps you mean count in projection criteria. I think is better if the expression ask the IType, of a specific function, to the dialect to don't have different behaviour between Query and Criteria.
