Recently while troubleshooting performance issues on our Production system,
our DBA team has identified some unused indexes on T2356 (HPD:Help Desk
form) and suggested us removing them could improve the query performance
and clean up some space in the Database. We have verified the same from
From what I can tell of the table you provided -- none of the indexes are
being used.
So - deleting them would have no affect.
Except (and this is a stretch) ... not having these indexes exist means

maintenance of indexes must occur at the DB level. Apart from that, I
don't know why one would remove indexes from a form, unless it's a form no
