SQL Server ORDER BY and DISTINCT is not parsed

[unruledboy]

The following query has order by clause:

SELECT p.Name FROM Production.Product p inner join dbo.productdetails pd on p.id=pd.productid
group by p.Name
order by p.name

And even with MsSqlDialect, the following sample code will return select.SortBy as null:

 var sql = @"SELECT p.Name FROM Production.Product p inner join dbo.productdetails pd on p.id=pd.productid
group by p.Name
order by p.name"
 var statements = new Parser().ParseSql(sql, new MsSqlDialect());
 foreach (var item in statements)
 {
     if (item is Statement.Select selectStatement)
     {
         var select = selectStatement.Query.Body.AsSelect();

        // select.SortBy is null
      }
}

And the issue happens with DISTINCT:

SELECT distinct p.[Name] FROM Production.Product p inner join dbo.productdetails pd on p.id=pd.productid

The select.DistributeBy is null.

Is there specific option that we need to use to support it?
