In dynamic SQL the SQL statement is prepared each time
before the Run time.But this not the case with static SQL
it ll be stored in shared SQL area and this will refered if
same Query is used again.So static ll be faster

Answer / deshabandhu bar
Static query is faster as this keep the Execution plan in
the lib cache. Also it keeps data blocks in the buffer
cache. Next time when a user try to execute the same query
the user hit the cache and execution plan will be ready for
that user. So the time required for parsing and creating
execution plan will be 0. So the Static query is faster
than the dynamic query.
