Temporary Row Number List

The Temporary Row Number List icon indicates that a temporary row number list was created in order to help process any selection criteria. A row number list is a data structure used to represent the selected rows from a table that matches any specified selection criteria. Since the selected rows are represented by a sorted list of row numbers, multiple lists can be merged and combined to allow for complex selection and processing to be performed without having any paging occur against the table itself.

Also referred to as: Dynamic Bitmap

Note: A temporary row number list is an internal data structure and can only be created by the system.
