SelectElement

trait SelectElement extends ExpressionNode

SelectElement are elements of a select list, for example they are a,b, and c in :

select a,b,c from T

they are either ValueSelectElement for composite expressions, i.e. select (x / 2) * y as Z from .... TupleSelectElement for group by or compute elements (TODO: document group by/compute) FieldSelectElement for table columns (that map to fields)

ExportSelectElement for a select element that refers to a SelectElement of an inner or outer query.

SelectElementReference are nodes in any clause other than select (where, having, composite expression, order by, etc) that refer to a SelectElement

    Update, Insert, and Delete statements are always at the root of an AST, so they are never aliased, but then can have sub queries, ex.: update ...

    Update, Insert, and Delete statements are always at the root of an AST, so they are never aliased, but then can have sub queries, ex.: update ... where x in (subquery). Name clashes are impossible since SelectElements of query are always aliased.
