class %Library.DynamicObjectQuery extends %Library.DynamicSQLQueryThe %DynamicObjectQuery class is used for defining class queries based on runtime Object/Bitmap statements.
qHandle is query-defined data and is typically updated by Fetch.
The Fetch method should set Row to be a $List of values corresponding to the columns of the query. If we are past the end of the data and no row is returned, Row should be set to null string (""). If the non-empty row being returned is the last one, AtEnd could be optionally set to 1, indicating that an additional call to Fetch may be avoided.
Row may also be subscripted. If any of the columns in the row are stream orefs then the oref type information is lost in the Row $list encoded value. To retain the oref type, place the oref into Row(columnNumber). %Library.ResultSet recognizes this form and will extract the column value as the subscripted value.
