For best results on large tables, collect SUMMARY statistics only on non-partitioned tables. Other recommendations for large tables include collecting statistics on:

  • All indexed columns
  • All frequently joined columns
  • Columns frequently referenced in WHERE clauses, particularly if the column contains very skewed, nonunique data
  • The system-derived column PARTITION (for all row and column-partitioned tables)
