When do we use the UPDATE_STATISTICS command?
Answer Posted / sivakumar
That command is used to rebuild indexes on tables, which
can speed up queries. You might want want to do it whenever
a large amount of data has been deleted or added. It can be
complicated to determine whether it is more efficient to do
this, or to just let the statistics rebuild automatically
so, as usual, testing is called for in each individual case
to get optimal performance.
