public abstract class ColumnExpressionImpl
extends Object
implements ColumnExpression

Abstract base class for column-specific SQL expressions.

This class provides a foundation for creating SQL column expressions by encapsulating a Column and offering a method to access it. It is designed to be extended by concrete implementations to define specific behaviors and SQL representations.

Classes that extend ColumnExpression are expected to implement the toSql method from the SelectExpression interface.
