ColumnName Attribute
Data Type: varchar(50)
4GL Access: RW
The ColumnName attribute contains the name of a database column in one of the tables used by the query object. This attribute is not relevant if the IsExpression attribute evaluates to TRUE.
This attribute is relevant only for a query object and its subclasses and not when used in conjunction with a DataStream or SQLSelect object.
