Manually forward a sequence - oracle sql -

-

i need forward set of sequences dml access. due bug in piece of code several values grabbed without sequence instead manually, sequence duplicating values. so, push sequence max value next time nextval called, gives value higher maximum. i've got 50 sequences each have go few thousand forward.

is possible dml access? if so, how should go it?

you can use dynamic sql this. example, bit of code select next 10,000 values each of list of sequences.

declare   l_num integer; begin   seq in (select *                  all_sequences                 sequence_name in (<<list of 50 sequences>>)                    , sequence_owner = <<owner of sequences>>)   loop     in 1 .. 10000     loop       execute immediate           'select ' || seq.sequence_owner || '.' || seq.sequence_name || '.nextval dual'          l_num;     end loop;   end loop; end;

if had ability issue ddl against sequence, use similar approach set increment 10,000, select 1 value sequence, , set increment down 1 (or whatever now).
