Sequence values

I have a sequence whose max value with the help of a trigger is inserted in a table column. I've noticed that sometimes the consecutive values of the sequence differ not by one but by variable number.
I have Increment by 1 and Cache 20 in the sequence.
It's not making me major problems, but I's wondering whats the deal?
thanks

Hello,
Take a look at the following AskTom thread which explains what you're seeing -
http://asktom.oracle.com/pls/asktom/f?p=100:11:0::::P11_QUESTION_ID:530735152441
In short, nothing to worry about, the way they're working is to maximise scalability.
BTW, if your application has frequent simultaneous updates to that table, then you will benefit from creating the sequence with a larger cache (rather than just 20).
Hope this helps,
John.

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
Ali

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"
public void setSeq(Number value)
// 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)
/* throw new OAAttrValException(OAException.TYP_ENTITY_OBJECT,
getEntityDef().getFullName(), //getSeq(), // EO name
getPrimarykey(), // EO PK
"Seq", // Attribute Name
value, // Attribute value
"AK", // Message product short name
"FWK_TBX_T_EMP_ID_NO_UPDATE"); // Message name */
if (value != null)
// Seq ID must be unique. To verify this, check both the
// entity cache and the database. In this case, it's appropriate
// to use findByPrimaryKey() because you're unlikely to get a match, and
// and are therefore unlikely to pull a bunch of large objects into memory.
// Note that findByPrimaryKey() is guaranteed to check all employees.
// First it checks the entity cache, then it checks the database.
OADBTransaction transaction = getOADBTransaction();
Object[] employeeKey = {value};
EntityDefImpl empDefinition = jobperfEOImpl.getDefinitionObject();
jobperfEOImpl Seq =
(jobperfEOImpl) empDefinition.findByPrimaryKey(transaction, new Key(employeeKey));
if (Seq != null)
/* throw new OAAttrValException(OAException.TYP_ENTITY_OBJECT,
getEntityDef().getFullName(), // .getSeq(), // EO name
getPrimaryKey(), // EO PK
"Seq", // Attribute Name
value, // Attribute value
"AK", // Message product short name
"FWK_TBX_T_EMP_ID_UNIQUE"); // Message name */
// 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.
setAttributeInternal(SEQ, value);
} // end SetSeq
I am sorry if I have confused you. I really did not mean to do it.
Thanks,

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.

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:
Example
No     Transfer Date     Bank Reference Number
(DDMMYY_999)
1     24-Oct-2010     241010_001
2     24-Oct-2010     241010_002
3     25-Oct-2010     251010_001
means every day sequence should start with the date initials.
Kindly give your valuable input.
Thanks
Sims

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.

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');

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);

How to get sequence value?

hi,
i'm trying to store sequence's value into a variable... smth like this:
create or replace function my_funct() as integer
is
begin
return my_sequence.currval;
end;
and "return my_sequence.currvalue" doesn't seem to work...
also i'would like to store that value into a variable, like:
is
i integer;
begin
i := my_sequence.currval;
end;
this also doesn't seem to work
regards

Hi,
You will using this method to store sequence value to variable
declare
i number;
begin
select sq.currval into i from dual;
dbms_output.put_line(i);
end;

Prevent skipping sequence value?

We created a sequenential PK populated from a another database table. We take value from this table and update last sequence value.
( IN ADF faces 11g app)
But if an error in commit processing of page, sequence is populated on the screeen. Error can be formatting error, validation error or etc
Then we correct format mistakes a new number is popolated at PK field.
So some values are skipped.
How can we prevent skipping sequence value? it is very important issue in our bussiness case.
Thanks...

We write code in doDML metdod of entity object as following mypackage.getmaxno().
We can posponed getting max no formatting till commit time. Where we need to write code to prevent the gap ?

if(operation==DML_INSERT){
String sql="{?= call mypackage.getmaxno()}";
CallableStatement cs=getDBTransaction().createCallableStatement(sql,0);
try {
cs.registerOutParameter(1,OracleTypes.VARCHAR);
cs.execute();
String MaxNo=cs.getString(1);
setMaxNo(evrakNo);
createDoc();
} catch (SQLException f) {f.printStackTrace();}

Last identity \ sequence value

Hello,
I have a little problem in some code I have written.
I have a database trigger that sequences rows for me on a transaction being entered into the database table.
However, as the return value of the procedure I have written I want this value to be returned.
How do I get the PK (eg sequence number) of the last record that was placed into the database table.
I am guessing that there is some form of sequence.last construct but I can't help being concerned by concurency issues (eg will the last sequence value always be the sequence that my trigger used)
Any advice will be gratefully recieved.
Regards

You can just use ROWNUM Pseudocolumn
select rownum id, header_id,order_number from oe_order_headers_all

Inserting oracle sequence values

hI
Do i need to do a select sequence.nextval from dual
before i insert the next sequence value into the table
For eg i tried using the foll insert statement but i get an invalid number exception
insert into parts(PARTS'DATABASE.PARTNOSEQ.NEXTVAL',"+PARTNO+")
But i get the above exception.I dont do a select now.
Thanks
Arn

Hi
I tried doing the following trying to insert sequence values but I still get an invalid get Column error.
sql4 = "select PART_SEQ.NEXTVAL FROM DUAL";
ResultSet rs3 = stmt2.executeQuery(sql4);
while (rs3.next())
seqVal = rs.getInt("PART_SEQ");
rs3.close();
for(int i=0; i<=count; i++)
{ // for loop
     sql3 = "Update part " +
     " SET part_mfr = '"+mfgcodeStr+"' ,
     " part_id = "+seqVal+"," +
     " WHERE invoiceno = '"+invoicenoStr+"' ";
Thanks

Insert multiple rows in on table and retreive sequence values

Hello,
I'm searching a way to insert several rows in a table that needs a sequence and retreive its.
For one row i use ExecuteScalar method with the following SQL is :
INSERT INTO MY_TABLE(MY_PK)
VALUES(SEQ_MY_TABLE.NEXTVAL) RETURNING MY_PK INTO :MY_PARAMETER
The aim is to insert several rows at one time. Currently I execute this SQL :
INSERT INTO MY_TABLE(MY_PK, MY_VALUE)
SELECT SEQ_MY_TABLE.NEXTVAL, MY_VALUE
FROM (
SELECT 0 MY_VALUE FROM DUAL UNION ALL
SELECT 1 MY_VALUE FROM DUAL
This query works well but i'm wondering how to retreive all sequence values generated by this query.
Is it possible and how ?
Thank you.
Sebastien

I tried this :
string sql = "INSERT INTO MY_TABLE(MY_PK, MY_VALUE) " +
"SELECT SEQ_MY_TABLE.NEXTVAL MY_PK, MY_VALUE FROM ( " +
"SELECT 0 MY_VALUE UNION ALL " +
"SELECT 1 MY_VALUE) " +
"RETURNING MY_PK BULL COLLECT INTO : RETURN_IDS";
using(var manager = myFactory.CreateDbManager()) // Initializes the connection and encapsulates ADO objects
manager.SetCommand(sql);
var cmd = (OracleCommand)manager.Command;
cmd.ArrayBindCount = 2;
var p = new OracleParameter();
p.DbType = DbType.Int64;
p.ParameterName = "RETURN_IDS";
p.Direction = ParameterDirection.Output;
p.CollectionType = OracleCollectionType.PLSQLAssociativeArray;
p.Size = 2*sizeof (long);
cmd.Parameters.Add(p);
cmd.ExecuteNonQuery();
var result = (Oracle.DataAccess.Types.OracleDecimal[])p.Value;
But I have an error ORA-00933 that indicates that the query is wrong at "RETURNING MY_PK".

Inserting sequence value from JDBC and getting the same value back

Hi: Gurus I have a table whose primary key is a sequence. I wonder how to make sure I get the same sequence value back for current transaction so I update the other table whose foreign key is the sequence value from first table.
E.g lets say I do this
String query_insert = INSERT INTO table1 (column1, ....) VALUES (HIGHLIGHT_ID_SEQ.nextval, ...);
pstmt = con.prepareStatement(query_insert);
pstmt.executeUpdate();
How I make sure no other transaction update the sequence value so I can read the last inserted sequence value and update the second table with this value
String query_select = "SELECT HIGHLIGHT_ID_SEQ.currval FROM DUAL";
pstmt = con.prepareStatement(query_select);
Regards,
Rashid.

<rant>No version again. I wonder why people requiring help want to stay anonymous and never want to type their version, only 4 digits. In this case, jdbc, not only the version of the driver is important, but also it's type. Waving a magic wand again? </rant>
Look up the returning into clause of the insert statement in the sql reference manual for your version.

Sequence value

Hi all,
I want to see current sequence value other than issuing sequence.currval. Although first time you can't see the current value of sequence without issuing sequence.nextval. only after issuing sequence.nextval you can see the current value of it. So how I can see the current value of sequence for the first time after start the database instance. Is it possible or not.

select * from dba_sequences where sequence_name = 'YOUR_SEQUENCE_NAME'
This will not work if sequence has CACHE (default is CACHE 20).

OGG Bidirectional Sequence value replication - HELP

Hi OGG Experts,
I have a Bi_Directional config in my systems and as per the OGG Doc, Sequence value replication is not Possible in Bi-Directional Config.
1) Why is it, I can't do sequence value replication in Bi-Directional config.
2) If I can do, what are all the ways?
3) I found odd and even sequence method but is it preferable to use this method. IF not, what are other ways to accomplish it.
~ Lother

On the source, the sequence value is in the redo stream. When it gets sent to the target, why generate another sequence value for something that is already present in what replicat is going to apply on the target?
Odd/even or a staggered order (start with 1,2,3 and increment by 3) for more than two is the way to go.
