public class ResultSetColumn
extends org.eclipse.birt.report.model.core.Structure

This class represents one column in the result set.

This is a managed object, meaning that all changes should be made though the command layer so that they can be undone and redone. Each result set column has the following properties:

Name
a result set column has an optional name.
Position
a result set column has an optional position for it.
Data Type
a result set column has a choice data type: any, integer, string, data time, decimal, float, structure or table.
