Hi,
I am trying to use an index I made like so...

where trunc(visit_date) >= trunc(to_date(......

And explain plan says it is always a Full Table Scan.

Oracle says there is a bug called
Bug#902521 8.1.5 RDBMS
Abstract: FUNCTION BASED INDEX ON TRUNC(DATECOLUMN) IS NEVER USED

Does anybody have experience with this or maybe a work around.

Thanks

A possible workaround would be to add another column which held the trunc of the date and then index that column
