Hi

I know the usage Statistic based on DML also on DBMS_STATS . REPORT_COL_USAGE. But i mean usage statistic based on select column from table queries. Without Join predicat or smth. like that.

I heared about the heatmap. But it is based on an licencing Feature.

Amy Suggestionen?

Many thx
Tom

sys.col_usage$ reports on not just ins/upd/del, but select as well, but as you allude to, this is for columns as predicates, not in the select list.

You can use fine grained auditing for this. An example here

and a set of docs and tutorials etc here
