Modification of sequences is a relatively
simple process. However, the main
concern related to changing sequences
is monitoring the effect on tables or
other processes that use the values
generated by the sequence.
For example, resetting the value
returned by the sequence from 1,150
back to zero is not a problem to
execute. Once performed, there could
be repercussions if the sequence was
used to generate primary keys for
a table, of which several values
between zero and 1,150 were already
