hello all,

I have a pl/sql procedure that selects the nextval from a sequence. The problem is that it incrrements the sequence by 2 in a pl/sql procedure. If I select the nextval from a sqlplus session, it works fine.

here is partial code that I am using.

PROCEDURE NEWTRANSACTION (v_storyid IN story.story_id%type,

                 		            v_transid OUT story_transaction.trans_id%type ) IS

BEGIN
select story_transaction_seq.nextval into v_transid from dual; .....
END for debugging purposes, I made that code look like...

PROCEDURE NEWTRANSACTION (v_storyid IN story.story_id%type,

                 		            v_transid OUT story_transaction.trans_id%type ) IS

v_value1 NUMBER; --debug code
v_value2 NUMBER; --debug code

BEGIN

  select story_transaction_seq.currval into v_value1 from dual; --debug code
  select story_transaction_seq.nextval into v_transid from dual;
  select story_transaction_seq.currval into v_value2 from dual; --debug code

.....
END when I ran this, v_value1 had a 200, v_transid had a 201, and v_value2 had a 202

taking the debug code out and hitting that procedure with a web page will increment the v_transid by 2 each refresh of the page.

am i doing something wrong? I can't find any information on the web related to this issue.
