I have an aswer, in dbc.tables i have the column access count, this contain the access number of a view, table...
I understand that this can have 0 access, but which is the diference between 0 access and null access, because i have some with 0 access and null acess.
Thaks a lot.
AccessCount will be NULL if it's not (or was never) collected, it's zero when the count was reset using one of the dbc.Clear???UseCount macros.
