Not finding anything online. I was looking for a dictionary view that might help me see how volatile a particular column was. sys.col_usage$ can show me when it is used in predicates, and dba_tab_modifications can show me how often a table is updated, but I am looking for something in between. Came across this object, but no data. I was hoping that statistics_level=allwould show me some data, but so for my testing has not born any fruit.
If there is a better source to go against, please let me know. I thought about logminer, but I rather go with a less intrusive method if at all possible.
TIA
