Hi!

 i have a  simple question,  if the master table have an index, must  i have create  the same index in a child  table?
what is  the best practice  for  indexes  in table partition ?

Indexes are self-contained within the physical table on which they are defined.  The index on the master contains no rows that are present in the child table.

wish to share my fantasy is entirely up to you.
