Statistics collection recommendations – Teradata 14.0 - comment by carrie

Raj,
 
When you collect stats on a volatile tables, those stats are held in the memory of the parsing engine.  They are not written to the data dictionary.   They can be viewed using the same methods as you would use to view stats and or the histogram of stats on a perm table, but they only stay in memory for the life of the transaction.
 
Thanks, -Carrie
