public ref class ExprLookup : IExpr, IQueryNode |
Remarks
MyTable[{expr1}, {expr2}].field is semantically correct if MyTable
is GROUPed by the same number of fields as the number of expressions
within brackets "[...]", and field is a derived property defined
on MyTable. Brackets with no expression list within represent access
to a table that is GROUPed to a single record.
Note that because the implicit tables NavStateRecords and AllBaseRecords are not GROUPED, it is not possible to do a lookup on these tables.
