I hace a table with 5.5 million rows which is joined with a GTT which is having 10,000 rows,  the query is going for a FTT despite there being a primary key index on the column which is used for the join, why is it going for  a FTT when the index is present and when the stats are up to date.

why is it not using the index?

will the behavior be different in a single instance & RAC environment

Howdy, Stranger!
