public interface ValueExpression

extends org.eclipse.emf.ecore.EObject

A representation of the model object 'Value Expression'. 4.14.5 Base columns and generated columns A column of a base table is either a base column or a generated column. A base column is one that is not a generated column. A generated column is one whose values are determined by evaluation of a generation expression, a whose declared type is by implication that of the column. A generation expression can reference base columns of the base table to which it belongs but cannot otherwise access SQLdata. Thus, the value of the field corresponding to a generated column in row R is determined by the values of zero or more other fields of R.
