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-request & sequence values

Trying to employ a seq value (not null, key field) along with insert-request causes ORA-01400. Current transform produces:
<field1>sequencename.NEXTVAL</field1>
<field2>fieldvalue1</field2>
<fieldn>fieldvaluen</fieldn>
Since I don't know how many rows will be inserted, I can't really select sequencename.NEXTVAL from dual.
Any suggestions?
JV

ok, we figured it out. make certain your before-insert trigger is properly established, and make no reference whatsoever to that column in your transform.xsl that is used in conjunction with the insert-request.
As the insert-request performs the insert (presumably the same for update-request), the trigger will obtain the next seqval, and the transform, if properly formed in canonical format, will pass the xml tree to the insert-request and the fields will be inserted "clean as a whistle".!

Bind variable with Oracle sequence

can we insert oracle sequence with the bind varaible
some thing like
seq       number(5);
begin
select myseq.nextval
        into seq        from dual;
dbms_sql.parse( l_cursor,insert into mytable (c1,c2,c3) values (seq,:1,:2),dbms_sql.native );
dbms_sql.bind_variable( l_cursor, :1,58);
dbms_sql.bind_variable( l_cursor, :2,9);
l_status := dbms_sql.execute( l_cursor );
end;
Thanks!

What are you trying there..
Why dynamic SQL?
Where is the exception block?
you have to use 'using ' to work with these kind of dynamic variables. Something like this (ugly code below)
CREATE SEQUENCE myseq;
create table mytable (c1 number,c2 number, c3 number;
DECLARE
   seq   NUMBER (5);
   A number;
   b NUMBER;
BEGIN
   SELECT myseq.NEXTVAL INTO seq FROM DUAL;
   a := 1;
   b := 58;
   EXECUTE IMMEDIATE 'insert into mytable (c1,c2,c3) values (:seq,:1,:2)'
      USING seq, a, b;
   a := 1;
   b := 100;
   EXECUTE IMMEDIATE 'insert into mytable (c1,c2,c3) values (:seq,:1,:2)'
      USING seq, a, b;
   COMMIT;
END; --- Check you need to have proper exception block.

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:

How can i achieve this?
Thanks,

looks like you might be looking for a custom sequence manager.
you might want to consider using a trigger to do this.
unfortunately if you use just one trigger you will probably get a mutating exception.
so you may need to do a multiple trigger approach
make a place to hold the rows you want to look at
i called mine tad_mgr
CREATE OR REPLACE PACKAGE TAD_MGR IS
* This package spec holds the row ids of the tad table to be used in the 3 trigger approach
type ridArray is table of tab.ID%type index by binary_integer;
newRows ridArray;
empty ridArray;
END;
/your 1st trigger clears out any left over rows you have.
CREATE OR REPLACE TRIGGER TAB_1ST
    before INSERT of ID ON TAB
declare
* This is the 1st trigger in 3 trigger approach to manage seq cds on the tad table
begin
                TAD_MGR.newRows := TAD_MGR.empty;
end;
/your second triggers puts your new or updated row into the container
CREATE OR REPLACE TRIGGER TAB_2ND
BEFORE INSERT
OF ID ON TAB REFERENCING NEW AS NEW OLD AS OLD
FOR EACH ROW
declare
This is the 2nd trigger in 3 trigger approach to manage seq cds on the tad table
begin
             TAD_MGR.newRows( TAD_MGR.newRows.count+1 ) := :new.id;
end;
/finally your last trigger does the updates.
CREATE OR REPLACE TRIGGER TAB_3RD
AFTER INSERT OF ID ON TAB
declare
This is the 3RD trigger in 3 trigger approach to manage seq cds on the tad table
aSEQ tab.seq%type;
aId   tab.id%type;
begin
for i in 1 ..TAD_mgr.newRows.count loop
    select ID, SEQ into aId, aSeq from tab where id = taD_mgr.newRows(i);
    for c in (select id, seq FROM tab where seq >= aSeq and id != aid ) loop
        update tab
        set seq = c.seq + 1
        where id = c.id;
    end loop;
end loop;
           taD_mgr.newRows := taD_mgr.empty;
   end;
/I just did this for the insert just as an example but you can change the triggers to insert or update and change the logic accordingly

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.

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);

Need to get sequence value in another column in oracle

Hi ALL,
I have sql query as below
select header_id,order_number from oe_order_headers_all.
and data it is displaying as
heder_id     order_number
111            500001
121            500400
I need to display another field with some sequence value like as below
id     heder_id     order_number
1      111                    500001
2      121                    500400
so how to get sequence value in another column please help me on this.

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

Mixing sun-database-binding with Oracle sequences

Hello,
I wish to insert rows inside the database, for instance rows representing persons, and rows representing their addresses. Primary keys for both person and address are Oracle sequence based.
My question is, if I insert a person, then one of her address, how can I retrieve the person ID for the address row to reference it.
The insert statement for the person is (for the moment) as follow
insert into Person (PERSON_ID, FIRST_NAME, LAST_NAME) values (PERSON_SEQ.nextval, ?, ?)The problem with this approach is that I never know the person ID, and am unable to make any references to it in the address row.
I tried to add an operation in the NetBeans generated person table WSDL. This operation would execute this statement:
select PERSON_SEQ.nextval from dualBut, for the moment, it's a failure.
Could you provide me with some hints?

Hi,
First I would advise you to register and post on the [email protected] alias - you can find the details of how to do this on the OpenESB site..... you'll reach a larger audience this way.
Second, you need a Stored Procedure in Oracle to do this, then use this from the DB BC, here's one I created which does something similar, i.e. returns a value I'm interested in after an "Update" statement....
CREATE OR REPLACE PROCEDURE "NEXTAPPNUMFINDER" (nextAppNum OUT NUMBER)
IS
BEGIN
UPDATE ACTIVE_APPLICATION_NUMBER
SET APPLICATION_NUMBER_NEXT = APPLICATION_NUMBER_NEXT + 1
RETURNING APPLICATION_NUMBER_NEXT
INTO nextAppNum;
END;
Hope this helps

Using oracle sequence in SQL Loader

I'm using oracle sequence in control file of sql loader to load data from .csv file.
Controlfile:
LOAD DATA APPEND
INTO TABLE PHONE_LIST
FIELDS TERMINATED BY "," TRAILING NULLCOLS
PHONE_LIST_ID "seqId.NEXTVAL",
COUNTRY_CODE CHAR,
CITY_CODE CHAR,
BEGIN_RANGE CHAR,
END_RANGE CHAR ,
BLOCKED_FREE_FLAG CHAR
Datafile:
1516,8,9,9,B
1517,1,1,2,B
1518,8,9,9,B
1519,8,9,9,B
1520,8,9,9,B
1521,8,9,9,B
1) As first column uses oracle sequence, we have not defined that in datafile.
This gives me error "Can not insert NULL value for last column"
Is it mandatory to specify first column in datafile, even though we are using sequence?
2) Another table is referencing PHONE_LIST_ID column (the one for which we using sequence) of this table as a foreign key.
So is it possible to insert this column values in other table simultaneously? Sequence no. should be same as it is in first table...
Kindly reply this on urgent basis....

use BEFORE INSERT trigger
with
select your_seq.nextval into :new.id from dual;

JPA: Oracle Sequence Generator not up to date

Hi,
I'm using the JPA Oracle Sequence Generator in one of my JPA classes:
@Entity
@Table(name = "DACC_COST_TYPE")
public class JPACostType implements Serializable {
@SequenceGenerator(name = "CostTypeGenerator", sequenceName = "DACC_COST_TYPE_SEQ")
    @Column(name = "ID_COST_TYPE")
    @Id @GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "CostTypeGenerator")
    private Integer idCostType;
In order to persist a new object I perform the following code:
@PersistenceContext
private EntityManager em;
JPACostType myJPA = new JPACostType();
myJPA.setIdCostType = null;
em.merge(myJPA);
em.flush();
Normally this works fine. But after deploying the app there sometimes happens an error:
Caused by: javax.persistence.PersistenceException: SQLException while inserting entity {com.karmann.dacc.ejb.busilog.jpa.JPACostType(idCostType=4)}.
at com.sap.engine.services.orpersistence.core.PersistenceContextImpl.flush(PersistenceContextImpl.java:278)

... 52 more
Caused by: java.sql.SQLException: ORA-00001: unique constraint (AEMA.DACC_COST_TYPE_PK) violated
Obviously JPA does not fetch the new key by accessing the Oracle sequence. This documents "next value = 5". Does JPA fetch the new key from its cache? Is there any possibility to avoid this?
Thanks for each hint,
Christoph

Hello Christoph Schäfer ,
I am stuck with a similar issue. I was able to save mutiple entries and there has not been much change to my JPA. I added new entities and new sequences.
Now, I get the error Caused by: javax.persistence.PersistenceException: java.sql.SQLException: ORA-02289: Sequence ist nicht vorhanden.
I have checked the name of sequence and sequence next val on the DB. It works on DB but when i execute it from ejb, it gives me thsi error. Now, it gives the error for all previously working JPA entities.
I have also provided allocationSize = 1 for all entities.
Please let me know, possible cause/solution to this issue.
thank you.

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');

Back numbers in Oracle sequences

We are using a J2EE based tool that uses Oracle as backend. For several purposes the tool use the oracle sequences. As per general rule the every time the sequence is referred, it generates a next higher number and returns the same for any kind of storage purposes like primary key, etc. But in rare cases we have got a previous number of the sequence instead of a next higher value. We aren't sure if that previous number was ever used before or not. But the problem is how does the oracle sequence return a previous number? e.g. we have a sequence running as 220, 221, 222, etc. then suddenly instead of returning 223 the next time, it may give the number 214 (or basically any previous number).
Does anybody know why does that happen? What could be the possible reasons and how it can be avoided? It creates confusion amongst users and does not seem just right to get a previous number. Any help is appreciated. Thanks.

Connection pooling should have no effect on this issue since the Oracle sequences should be cached in Oracle and not in the pooled session.
RAC as mentioned would since each instance would have its own sequence cache: instance A values 1 - 5, instance B values 6 - 10, instance C 11 - 15.
Then depending on which instance the user session was connected to the ticket numbers would appear to be selected from an earlier point in the sequence.
On a non-RAC instance you can see this apparent behavior where the application gets the sequence number on the first screen and passes the value to later screens but the number is not inserted into a database table until the final screen that creates the ticket. If it takes the user longer to create the ticket than other users who started later then the ticket number would appear earlier than the earlier created tickets.
The solution to this "problem" for non-RAC or RAC is to insert a timestamp at the time of ticket creation (or start) and to process the tickets in timestamp rather than ticket number order. After all the ticket number is just an identifier and there is really no logical reason that tickets have to be processed in ticket number order.
If it is a political issue then you could use a dual key system. Assign one key at creation time, transaction key, and then assign the ticket number via batch based on either the timestamp of when ticket entry started or was submitted. Now the ticket numbers represent whatever order you need. You can notify the users of the ticket number via email.
