Can a strored procedure contain Drop Sequence /Create Sequence statement?

I am trying to schedule a job to update the starting value of a sequence. So I need to write a strored procedure to drop and then recreate the sequence. But when i tried to cimpile the follwing stored procedue, it gave me the error "'DROP' is not a valid identifier". Is it illegal to have "Drop Sequence /Create Sequence " in a stored procedue? If this is true, is there any way to accomplish my task (simply recreate the same sequence with different starting value every month)? Thanks!
Begin
DROP SEQUENCE TEST_SEQ;
CREATE SEQUENCE TEST_SEQ
START WITH 0
MAXVALUE 999999999999
MINVALUE 0
NOCYCLE NOCACHE NOORDER;
End

In general, it is a bad idea to try to encode information into a key because it
- complicates queries in the future
- complicates updates to the data in the future
- can easily be generated on the fly from other data elements
Inevitably, if you do something like what was proposed, you'll find out that the data encoded in the key gets out of date from the data stored in the row, that users are writing queries that do things like strip off the first 6 characters of the string in order to do date searches, and that users discover they want to be able to modify the data to fix the data that's encoded in the keys, which can be terribly expensive if there are child tables.
Rather than trying to do this, I would store a DATE value and a non-reset sequence. You can always generate the reference number for the user by doing a TO_CHAR on the DATE and concatenating the output of an appropriate ranking function. If the users decide that they need to correct the DATE of an event, the reference number will be updated automagically since it was never stored in the database. A number generated in the query can also be guaranteed to be gap-free, which tends to please users.

Script to drop/re-create sequences is generated with errors

Hello,
I'm migrating an Oracle 10g instance running on Solaris 10 to an Oracle 11g instance running on RedHat Linux. I'm following the "Platform Migration" White Paper ( URLhttp://www.oracle.com/technology/deploy/availability/pdf/maa_wp_11g_platformmigrationtts.pdf ).
In the appendix, there's the code for a script that's supposed to generate an SQL script that drops and re-creates the sequences on the target machine:
set heading off feedback off trimspool on escape off
set long 1000 linesize 1000 pagesize 0
col SEQDDL format A300
spool tts_create_seq.sql
prompt /* ========================= */
prompt /* Drop and create sequences */

select regexp_replace(
dbms_metadata.get_ddl('SEQUENCE',sequence_name,sequence_owner),
'^.*(CREATE SEQUENCE.*CYCLE).*$',
'DROP SEQUENCE "'||sequence_owner||'"."'||sequence_name
||'";'||chr(10)||'\1;') SEQDDL
from dba_sequences
where sequence_owner not in
(select name
from system.logstdby$skip_support
where action=0)
spool off
I have run it on my Solaris machine, and it generates a file that looks like this:
/* ========================= */
/* Drop and create sequences */
/* ========================= */
CREATE SEQUENCE "MDSYS"."TMP_COORD_OPS" MINVALUE 1000000 MAXVALUE 2000000 INCREMENT BY 1 START WITH 1000000 NOCACHE NOORDER CYCLE

I don't have any "drop sequence" commands, and there is no semicolon (;) at the end of the "create sequence" lines, so those are not executed.
I'm not at all familiar with PL/SQL, could somebody point me to the error?
Thank you,
Adrian

Why do you need the "REGEXP_REPLACE ()" function?
This would be simpler:
SET long 32000 longc 80 pages 0 lin 80 trims on

       || sequence_owner

How to CREATE SEQUENCE in one table

dear all
the one thing i want to know when i use CREATE SEQUENCE in one table like this and then at that table
CREATE SEQUENCE oproduct_sequence
START WITH 1 INCREMENT BY 1
nocache
create table oproduct(
tname varchar2(20) not null,
tid int default oproduct_sequence.nextval
the system indicat that i cannot use this way to create table , so i really want to know how can i achieve this method
becuase when i want to insert inot table oproduct only use
insert into oproduct valuse('aaaa');
and the result like
aaaaa 1
bbbb 2

Actual name is before insert trigger. Some examples are listed below:
Example Number 1 ...
create sequence product_seq start with 1 increment 1
create or replace trigger product_insert before insert for each row begin
select productseq.nextval
into :new.product_id
from dual;
end;
Example Number 2 ...
How to create an autoincrement field in a table with a sequence ...
SQLWKS> create table bob(a number , b varchar2(21));
Statement processed.
First create a sequence
SQLWKS> create sequence x ;
Statement processed.
Then create the trigger.
create trigger y before insert on bob
for each row
when (new.a is null)
begin
select x.nextval into :new.a from dual;
end;
Example Number 3 ...
First create a sequence:
create sequence emp_no_seq;By default it increments by 1 starting at 0.
Use its values when inserting data into the table:
insert into t_emp values (emp_no_seq.nexval, 'Joe Black');~ Madrid.

Error when creating Sequence inside a stored procedure

I tried to drop a sequence and then re-create it with new starting number in a pl/sql procedure by using 'execute immediate' command.
However, I got the 'ORA-01031: insufficient privileges' error when I actually executed the procedure.
I was able to create the sequence directly from SQL*Plus prompt. So, I believe I have the sufficient privilege to create sequence.
Why it's not working when it's in a procedure?
Please advise. Thanks!

I'm not mean at all. You asked a redundant question, and you didn't research it or for less than 1 minute.
Doing so you add to the clutter, and contribute to turning this forum in a chatroom (which it isn't ) and to a place of garbage
(which it is thanks to you and thousands of other DBAs who never consult documentation before asking a question)
That's just the truth. I can't help it you can't bear to hear the truth. That is a problem with you, not with me.
I am in forums like this one for over 15 years. Over the years I have seen more and more people who don't want to learn to fish.
And as things are getting worser and worser: yes, it annoys me.
And I did anwer the question, didn't I. Frankly, all over the globe real DBAs are tearing their hair out (provided they still have it) because of the sort of 'applications' you and your colleagues develop.
They are a disaster.

Problem with creating sequence in procedure

I am getting the following error when trying to create a sequence inside a procedure:
ORA-01031: insufficient privileges
But, I have no problem creating the sequence outside the procedure, by just issuing the create sequence command.
How can I make this work?
Thanks.

I am getting different result for this:
INSERT INTO DEPNODE.SEQ_MEID (proc_id, me_id, seq_id)
SELECT 'tstamp' AS proc_id, M.MANAGED_ENTITY_ID AS ME_ID, ROW_NUMBER () OVER (ORDER BY M.MANAGED_ENTITY_ID) AS seq_id
FROM FDM.MANAGED_ENTITIES M, FDM.PHYSICAL_ADDRESSES P
WHERE M.MANAGED_ENTITY_ID = P.ME_MANAGED_ENTITY_ID
AND M.MANAGED_ENTITY_ID < 5;
If I ran this at the prompt, I get the correct result:
tstamp     1     1
tstamp     2     2
tstamp     3     3
tstamp     4     4
But, if its part of the procedure, I get this:
tstamp     1     1
tstamp     1     2
tstamp     1     3
tstamp     1     4
** the middle row is the seq_id

How can i pass the parameter for strored procedure from java

dear all,
I am very new for stored procedure
1. I want to write the strored procedure for insert.
2. How can i pass the parameter for that procedure from java.
if any material available in internet create procedure and call procedure from java , and passing parameter to procedure from java

Hi Ram,
To call the callable statement use the below sample.
stmt = conn.prepareCall("{call <procedure name>(?,?)}");
stmt.setString(1,value);//Input parameter
stmt.registerOutParameter(2,Types.BIGINT);//Output parameter
stmt.execute();
seq = (int)stmt.getLong(2);//Getting the result from the procedure.

How can I return the nextval of a particular sequence from a stored procedure?

I have a stored procedure that basically generates and records
nextval into a table each time the procedure is called. I want
to return this value in an out parameter. Is this possible? If
so, how do I implement it?

sq> create sequence s1 start with 1 increment by 1;
procedure to get the nextval from a sequence:
sql>create or replace procedure p1
(seq_no_p OUT Number)
is
Begin
select s1.nextval into seq_no_p from dual;
End p1;
to call the above procedure to get the out parameter(nextval):
declare
p number;
begin
p1(p);
end;
If this is what u want.

Hi,
If i want to create a sequence starting from 00500 to 99999, how can i do that?
Please note the sequence should start with 00500 and not 500. I tried creating one, but 00500 got converted to 500.

How can I insert a spreadsheet containing drop down boxes and links to other spreadsheets into a keynotes slide? Please help :(

How can I insert a spreadsheet containing drop down boxes and links to other spreadsheets into a keynotes slide? Please help
I need to retain all the formula's and the sheets these formulas are linked from.

Have you considered switching out of Keynote and over to your spreadsheet program when you get to this slide? If you launch the speadsheet program before Keynote you can switch using Command-Tab. You can then switch back into Keynote when you are done.
I realize that this is not what you were looking for but I don't think it is possible to do exactly what you want.

Sequence created in anon PL/SQL missing initial value

If I create a sequence in an anonymous PL/SQL block, with execute immediate, then perform a select nextval from that sequence outside the block, it misses it's initial value.
Easily reproducable here:
create table tab_a ( col_a number(4) not null );
begin
execute immediate 'create sequence seq_a start with 47 increment by 1';
end;
insert into tab_a select seq_a.nextval from dual;
select * from tab_a;
This is a much simplified representation of the circumstance I found myself in, but it reproduces the effect I see.
If I drop the sequence and truncate the table, and run the statements (excluding the first) again, it works as expected. If I drop the table and run all the statements again, it returns the wrong answer again.
I don't need a workaround, the issue has been addressed long ago, but I would like to know WHY this happens. starting the sequence at 47 can be any number, it's there just to show the issue when 48 is inserted into the table. The insert could be into any table, and the from could be over any table rather than dual.

Can you show the output you get like this? Mine is a 10g DB. But sure it would work in 11g DB as well.
