Class ColumnRef

Object

gudusoft.gsqlparser.ir.semantic.ColumnRef

public final class ColumnRef
extends Object

In-statement reference to a column. Holds the FROM-clause alias and the column name as they appear in the SQL — not the final physical table. Physical/provenance information lives on RelationSource's RelationBinding so that later CTE/subquery slices can describe provenance separately without mutating this shape.
