Sequence should always start with 1

Question

Hello,
i am using a sequence in a Mapping. But by starting the mapping the second or 3rd time the sequence did not begin with the value 1 but with the last value + 1 of the sequence in the 1st mapping.
Is it possible to use a sequence so that it always begins with the value 1 everytime you start the mapping?
Regards,

I'm not sure I quite understood what you want, lemme get this straight:
U have a sequence named SEQUENCE and you use it in 3 different mappings. When you finish run the first, you want it to restart counting?
If so, then, I'm afraid you'll have to re-deploy the sequence. But you don't have to do it in Control Center.
You may create a stored procedure that creates the sequence using 'EXECUTE IMMEDIATE' facility. Then, use it as a pre mapping process. It would be something like:
-- This one you'd use in the pre-mapping process
create or replace procedure Create_seq as
begin
execute immediate 'create sequence bla bla bla bla';
end;
-- This one you'd use in the post-mapping process
create or replace procedure drop_seq as
begin
execute immediate 'drop sequence bla bla bla bla';
end;
Then, using this procedures in each mapping you want to use the same sequence. That should be enough.
Good luck
