public interface DelegateExpression extends SelectExpression
Interface for nesting query expressions such as SQL functions.

This class provides a foundation for creating SQL function 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.
