Contains one row for each base table. Views or aliases are, therefore, not included. For typed tables, only the root table of a table hierarchy is included in this view. The CARD value applies to the root table only while the other statistics apply to the entire table hierarchy.
Note:  Summary tables are not included in this view for Version 5.2. If updating statistics for a summary table, use the OBJSTAT.TABLES view (see Appendix K. "Catalog Views For Use With Structured Types" for how to define this view).
