Alter sequence value

Hai all.,
im trying to import data from one database table(A) to other database table(B)
and almost all the fields in the two tables are same.
if i try to import the data from A to B.Im gettin problem with sequence
Can anybody help me on this....
Note :Table B has some values before importing values from A to B
and both the tables have sequences.
Thanks In Advance...

im trying to import data from one database table(A) to other database table(B)You are not being clear. Are you using the import utility to bring data from one insatnce of a table into another instance of the same table (i.e. t1 @a.world vs [email protected])? Or are you trying to run a SQL insert statement to bring data from one table into a different table within the same database instance?
The fixes are different in each case.
Cheers, APC

ALTER SEQUENCE on a busy server results in unexpected very high values

Our sequence was at 782,393,232 or so, when I bumped it up by 30,000. Here's the commands I used:
alter sequence OUR_SEQ increment by 30000;
select OUR_SEQ.nextval from dual;
alter sequence OUR_SEQ increment by 1;
commit;
When I queried the sequence's nextval a few minutes later, it had jumped to over 8 billion !?! I quickly reset down to 783 million or so, and it behaved propertly after that. I've seen a couple of posts on the net that infer that resetting a sequence while it is being heavily used can cause "unpredictable results". Has anyone else experienced this or is there a known bug ?
I'm running :
Oracle Database 10g Enterprise Edition Release 10.2.0.4.0 - 64bit, RAC system.
PL/SQL Release 10.2.0.4.0 - Production
"CORE 10.2.0.4.0 Production"

Sven,
I'm not sure that I understand what you're clarifying...
In a RAC cluster, a sequence with a cache has a separate cache in each node of the cluster. If the cache was set to 20 (the default), and the increment was set to 30,000, each node would cache 20 values each separated by 30,000. And the caches would be non-overlapping (i.e. node A would get the 20 values from 1 - 570,001, node B would get the 20 values from 600,001 - 1,170,001). I don't see that this is at odds with what I posted.
Obviously, the presence of a cache creates a bit of a wrinkle with when, exactly, you say that a sequence is incremented. The NEXT_VALUE in DBA_SEQUENCES is incremented by cache*interval when any node exhausts its cache. The NEXTVAL of a sequence for connections that are hitting a particular node will increase by interval each time some other session gets the NEXTVAL of a sequence. The NEXTVAL of a sequence for connections on a different node is unaffected by what is happening on the current node. Is that the clarification you're making? If so, I agree.
user11300030,
The discussion on sequence caching may provide some insight into why none of the rows are between 780 million and 1 billion. It's entirely possible that those values were cached on a node other than the node where the inserts were run. Had the caches not been flushed when you altered the sequence, inserts run on those other nodes might have used the values from that range.
JustinWe do have two nodes and the sequence cache size was 100, so what you suggested in your last paragraph makes sense.
Also, I just ran an AWR report and noted that "select our_seq.nextval from dual" was called 280K times (Hibernate is a hungry beast).

Changing the nextval of a sequence using alter sequence

Hello experts,
Is there any option to modify the nextval of a sequence using alter sequece command?
Thanks in advance.
J.Prakash

Hi
I do not think so there is any direct way to modify the nextval of a sequence, only workaround i can think of is firing two DDL
alter sequence dumm increment by 10
alter sequence dumm increment by 1Where first alter command would increment the nextval to (currentvalue + incement value) and second alter command would reset the increment to its original value in my case 1

Golden Gate Sequence Value replication?

Hi all,
I have searched the web, and read the Golden Gate documentation but I've found mixed answers.
I'm just trying to ascertain for certain whether it's possible to automatically replicate sequence values in a bi-directional configuration. Both databases will be identical and both will be 11gR2 with the latest version of GG.
If it is not possible to automatically increment sequences in a bi-directional configuration, what are the best practices for maintaing them?
One option is the alternate sequences on each database, one with even values (for example) and one with odd values, but this requires deployment of new sequences on both databases, something we were hoping would be taken care of by the replication. (yes the sequence creation can be taken care of but the value is not incremented on the target database).
another way that we thought of off the top of our heads is to have an on insert trigger (we only use sequences to generate surrogate keys) which will select nextval from the target database via a db link, but this seems somewhat cumbersome.
What is best practice?

Use sequence parameter... here is from Golden gate document:
SEQUENCE
Valid for Extract
Use the SEQUENCE parameter to extract sequence values from the transaction log forpropagation to a GoldenGate trail and delivery to another database. Currently, GoldenGate supports sequences for the Oracle database.
NOTE DDL support for sequences (CREATE, ALTER, DROP, RENAME) is compatible with, but not required for, replicating sequence values. To replicate just sequence values, you do not need to install the GoldenGate DDL support environment. You can just use the SEQUENCE parameter.
GoldenGate ensures that the values of a target sequence are:
● higher than the source values if the increment interval is positive
● lower than the source values if the increment interval is negative
Depending on the increment direction, Replicat applies one of the following formulas as a test when it performs an insert:
source_highwater_value + (source_cache_size * source_increment_size * source_RAC_nodes) <= target_highwater_value
Or...
source_highwater_value + (source_cache_size * source_increment_size * source_RAC_nodes) >= target_highwater_value
If the formula evaluates to FALSE, the target sequence is updated to be higher than the source value (if sequences are incremented) or lower than the source value (if sequences are decremented). The target must always be ahead of, or equal to, the expression in the parentheses in the formula. For example, if the source highwater value is 40, and CACHE is 20, and the source INCREMENTBY value is 1, and there are two source RAC nodes, the target highwater value should be at least 80:
40 + (20*1*2) <80
If the target highwater value is less than 80, GoldenGate updates the sequence to increase the highwater value, so that the target remains ahead of the source. To get the current highwater value, perform this query:
SELECT last_number FROM all_sequences WHERE sequence_owner=upper('SEQUENCEOWNER') AND sequence_name=upper('SEQUENCENAME');

Help on alter sequence

hi friends needed help immediately can we use the statement to alter a sequence value
ssss is a variable
EXECUTE IMMEDIATE 'ALTER SEQUENCE abcd_SEQ MAXVALUE '||ssss||'';
very urgently

EXECUTE IMMEDIATE 'ALTER SEQUENCE abcd_SEQ MAXVALUE
'||ssss||'';Why did you put quote after variable?
It'll work if you create statement like:
EXECUTE IMMEDIATE 'ALTER SEQUENCE abcd_SEQ MAXVALUE ' || ssss;

How to alter sequence next number

Can we alter sequence next number. I want to start it from minval.

To restart the sequence at a different number, you must drop and re-create it.
If you change the INCREMENT BY value before the first invocation of NEXTVAL, some sequence numbers will be skipped. Therefore, if you want to retain the original START WITH value, you must drop the sequence and re-create it with the original START WITH value and the new INCREMENT BY value.
Oracle Database performs some validations. For example, a new MAXVALUE cannot be imposed that is less than the current sequence number.

Altering sequence to start from 0

I have a sequence for auto-incrementing a value. Each day I want that sequence to restart, meaning to start from 0 again. So I did a job in which I tried deleting the sequence and re-creating it. Someone told me that instead of deleting-recreating a sequence I can use alter sequence to make the sequence start from 0 again but as I read, the alter sequence cannot do that. as I read:
ALTER SEQUENCE [schema.]sequence
[INCREMENT BY integer]
[MAXVALUE integer | NOMAXVALUE]
[MINVALUE integer | NOMINVALUE]
[CYCLE | NOCYCLE]
[CACHE integer | NOCACHE]
[ORDER | NOORDER]
there is no option to change start from.
Does anyone knows if that can be actually done?
As I figured it's not possible to alter the sequence to start from 0 again I can do a job in oracle to delete and create the sequence again. The thing it it's not working. If I do a job and say:
execute immediate 'drop sequence name_seq'; and execute it, it works, it deletes the squence but if I further write:
execute immediate 'create sequence name_seq ' ||
'start with 1 ' ||
'increment by 1 ' ||
'nomaxvalue ';
it doesn't do it anymore. I get no errors but the sequence is not created. can anyone give me a hand here? 10x a lot in advance

there is no option to change start from.
Does anyone knows if that can be actually done?ensure that noone other works with sequence and:
alter sequence seq increment by -(current_value);
select seq.nextval from dual;
alter sequence seq increment by 1;
execute immediate 'drop sequence name_seq'; and
execute it, it works, it deletes the squence but if I
further write:
execute immediate 'create sequence name_seq ' ||
'start with 1 ' ||
'increment by 1 ' ||
'nomaxvalue '; Looks OK, can you do that from jus SQL prompt?

Unable to save Sequence value to Database

Hi,
I am trying to pupulate a sequence value so that I can use it as primary key along with the combination of other columns later. My problem is that the sequence value is getting populated on the page with the right value, But is not getting saved to the database. The Column is there in the VO. The column is blank on the table. When I print it(System.out.println("Seq=" + xSeq.getText(pageContext));), the value is null. Can anyone please advice what I am doing wrong OR if I am missing anything here.
Thanks

Hi Tapash,
Thanks for all of you guys(Tapash/Sumit/user550094) help. The sequence is working and also populating the values in the table when I do not have any validation checks imposed on it.
If I add any validations as mentioned in the exercise for create page where it checks if the sequence can be updated while null and so on... and throws appropriate exception. I get error. That is the code that I mentioned above.
Here is the validation code for EOImpl:
As mentioned below in order for the code to compile and work I had to comment the "throw new OAAttrvalException". If I uncomment the
"throw new OAAttrvalException" part, it gives me the following error while compiling:
"Error(796,13): method getPrimarykey not found in class lac.oracle.apps.lac.jobperf.schema.server.jobperfEOImpl"

// Because of the declaritive validation that you specified for this attribute,
// BC4J validates that this can be updated only on a new line, and that this,
// mandatory attribute cannot be null. This code adds the additional check
// of only allowing an update if the value is null to prevent changes while
// the object is in memory.
if (getSeq() != null)

if (value != null)

OADBTransaction transaction = getOADBTransaction();
Object[] employeeKey = {value};
EntityDefImpl empDefinition = jobperfEOImpl.getDefinitionObject();
jobperfEOImpl Seq =
(jobperfEOImpl) empDefinition.findByPrimaryKey(transaction, new Key(employeeKey));

// Note that this is the point at which the value is actually set on the EO cache
// (during the scope of setAttributeInternal processing). If you don't make this
// call after you perform your validation, your value will not be set correctly.
// Also, any declarative validation that you define for this attribute is executed
// within this method.

I am sorry if I have confused you. I really did not mean to do it.

Using a single sequence value over multiple scripts (in a variable?)

Hi all...
I'm writing a number of scripts that insert rows into tables.
To better explain my point, I'll paste a simple breakdown of the scripts here as that will be easier to understand...
Script 1:
INSERT INTO WORKGROUP_DEPARTMENTS(ID, DEPT_NAME, DEPT_TYPE)
VALUES (SEQ_WGDPT.NEXTVAL, 'Staff', 3);
Script 2:
INSERT INTO WORKGROUP_SECTIONS(ID, SECT_NAME, WGDPT_ID)
VALUES (SEQ_WGSEC.NEXTVAL, 'Staff 1',
(SELECT ID FROM WORKGROUP_DEPARTMENTS
WHERE DEPT_NAME = 'Staff'
AND DEPT_TYPE = '3')
Script 3:
INSERT INTO WORKGROUPS(NAME, UNIT_TYPE, WGSEC_ID)
VALUES ('Staff Room', 3,
(SELECT ID FROM WORKGROUP_SECTIONS
WHERE SECT_NAME = 'Staff 1')
As you can see, in scripts 1 and 2 a new value is produced from a sequence (SEQ_WGDPT & SEQ_WGSEC respectively). Then, in scripts 2 & 3 (respectively) these values are inserted into another table.
What I'm trying to figure out is: can I do the same thing here without having to include the horrible SELECT statements in scripts 2 & 3 in order to find the ID, which was produced by the sequence in the previous script?
Unfortunately they do have to be separate scripts, and as such I can't call Sequence.CurrVal from a different script as other users may have used the sequence since it was used initially in the previous script. I could call it from the original calling script, and save it intop a variable, but I have no idea how to - even if it is the right idea!
I tried to insert the sequence value into a variable a la PL/SQL so that I could call this variable from the next script, but failed miserably as I'm rubbish!
Any help would be great. Thanks.

You can use PL/SQL, for example:
SQL> desc t
Name                                      Null?    Type
ID                                                 NUMBER
NAME                                               VARCHAR2(10)
SQL> desc t1
Name                                      Null?    Type
ID                                                 NUMBER
NAME                                               VARCHAR2(10)
ID1                                                NUMBER
SQL> desc t2
Name                                      Null?    Type
ID                                                 NUMBER

ID2                                                NUMBER
SQL> create sequence seq_1;

How to get sequence value on click of button in OAF Page

Hi all,
I have a requirement to get a field called Bankrefernece number populated with sequence value on click of apply button ; i mean inserting new record in database for new transaction.
Sequence Value should be something like this:

(DDMMYY_999)
1     24-Oct-2010     241010_001

Hi Anil,
Its a standard page & i want it on click of apply button but my question is when i click apply button it navigates to other page..is it possible in such scenario to extend the controller.
Thnx for ur suggestion
SimsThat is not an issue, you can extend the controller of that page and get the value of sequence and set it to the VO attribute.
Thanks

Need to populate sequence value in a field after insert in oaf page

Hi All,
I have a custom OAF insert page in that i need to populate a sequence value to a field once the data inserted successfully to the table.
so for that i followed the below approach.
1>Created a sequence in database.
2>In the EOImpl java file in the setter method for the respective field have written below code.
    public void setContainid(Number value) {
        if (value == null) {
                OADBTransaction t = getOADBTransaction();
                value = t.getSequenceValue("XXXXX_CONTAIN_SEQ");
        setAttributeInternal(CONTAINID,value);
But still i am not able to populate the sequence value for the field in my oaf page,please help me out on thsi.
Thanks

Hi,
Write this logic in create method of EOImpl:
public void create(AttributeList attributeList)
    super.create(attributeList);
    OADBTransaction transaction = getOADBTransaction();
    Number contID = transaction.getSequenceValue("XXXXX_CONTAIN_SEQ");
    setContainId(contID);

Hi,
You will using this method to store sequence value to variable
declare

select sq.currval into i from dual;
