Class MemberAccess

Describes access to a member, e.g.: In

From X In Timesheet Where X.BeginTime < #2012-10-10# Select X

"X.BeginTime" is referred to as a MemberAccess with the segments being 'BeginTime' and alias being X. The alias may be null (and is by default null). An Alias of null means that the Member access refers to the table source of the parenting query. As of 2012-11-09, this is not possible to achieve using the grammar, as it would require not specifying an alias. Pseudocode:

From Timesheet Where BeginTime > #2012-01-01# Select

would by a theoretical possibility for such a syntax.
