In addition to the set of general rules provided in General Rules For CREATE TABLE AS … WITH NO DATA, the following list of specific rules applies only to an AS … WITH NO DATA clause that does not specify a subquery.
  • Vantage copies all the available single-column statistics on source table columns as zeroed statistics.
  • Vantage copies all available multicolumn statistics except those multicolumn statistics that include the system-derived column PARTITION as multicolumn zeroed statistics.
  • Vantage copies all available statistics from source table indexes to the target table as zeroed index statistics when you do not define any indexes for the target table.
  • Vantage copies all available statistics on the system-derived PARTITION column and any multicolumn statistics that include the system-derived PARTITION columns in their column set as single-column and multicolumn zeroed statistics, respectively, from source table column sets to the target table as zeroed index statistics when you do not define any indexes for the target table.
