Hello expert,

I have a table with 40 millions records and the last update date is indexed. But when we use the following where clause, it takes forever to run the report.

   WHERE TRUNC(last_update_date) = TRUNC(SYSDATE - 1)

How to improve the performance? Do I need to create a new index field on the table with TRUNC(last_update_date)?
