Sequence and trigger

Hello,
Ia have created a Sequence and a trigger
The Sequence ïs:
CREATE SEQUENCE "WABO"."WABO_VERG_SEQ" MINVALUE 1 MAXVALUE 9999999999999999999999999999 INCREMENT BY 1 START WITH 1 CACHE 20 ORDER NOCYCLE;
The trigger is:
create or replace
TRIGGER WABO.WABO_VERGUNNING_TRIC
BEFORE INSERT ON WABO.WABO_VERGUNNING FOR EACH ROW
WHEN (new.WABO_ID IS NULL) BEGIN
SELECT WABO_VERG_SEQ.NEXTVAL INTO :new.WABO_ID FROM dual;
END;
When I insert a row in the table the sequence counter is 21 and it's stay's 21 even when I insert a new row
When I cal the DDL it's showes me this
CREATE SEQUENCE "WABO"."WABO_VERG_SEQ" MINVALUE 1 MAXVALUE 9999999999999999999999999999 INCREMENT BY 1 START WITH 21 CACHE 20 ORDER NOCYCLE;
What am I doning wrong.
Thanks

Creation of sequence and trigger for each table!!!!!!!1

Hi
I am new to trigger and Sequence field. In one of my database we have many tables with fields for specifing ID numbers. Iam planning to insert the ID field with help of a Sequence and trigger...that trigger fires by adding the sequence value from the dual table. Now the point is here we r having around *60* table with ID field. And i am planning use the above process for each table by creating sequences and trigger for each table.
Will this affects the performance of database.
Is there any other option other than the above process, I mean other than creating sequences and trigger for each table.
PLzz help to resolve this issuee......

Tiger, I didn't mind about your comment, but the point is try to use
select NVL(max(a) + 1,1) into i from p1_temp;This line in your trigger code and see what is happening. The problem is with your trigger. You are using group by function and you will not get no_data_found !
For more help, this is some modification of your code.
SQL> create table p1_temp (a number(10) primary key, b number(10));

SQL> create or replace trigger trg_p1_temp

Suppress auto sequence and trigger DDL for surrogate keys?

Is there a way to suppress trigger and sequence creation for surrogate keys when export to DDL file?
I know most of the time the automatic sequence and trigger creation is welcome and very handy.
However I'm migrating from an old Designer model and there only the needed sequences are created.
They have a different name and trigger logic is custom (and generated outside designer).
There is a lot of package code depending on this. So I prefer to create and use different sequences.
Is there a way to achieve this? Any tips are welcome.Create

Hi,
Note that generating the DDL for Oracle 12c means that it will attempt to use your Oracle 12c Physical model. So if you normally use Oracle 10g or 11g, you will find that any details from your Oracle 10g or 11g Physical Model will not be included. So this approach may have other implications for you.
If you are not using Oracle 12c, there are some relevant properties on the Auto Increment tab of the Relational Model properties dialog for the Column which may help:
Sequence Name - allows you to specify the name of the Sequence (which can be the name of a Sequence defined in the relevant Physical Model).
Trigger Name - allows you to specify the name of a Trigger (which can be the name of a Trigger that is defined for the Table in the Physical Model).
Generate Trigger - unsetting this will stop the Trigger being generated.

Oracle jdbc creating a table, sequence and trigger

I'm trying to create a table with a sequence and with a trigger for that sequence. When I do this within Oracle Express edition I have the following SQL statements. Which DO run correctly inside Oracle Express using the same user I log in with JDBC.
CREATE table "TEST" (
"ID" NUMBER(10) NOT NULL,
"NAME" VARCHAR2(20),
constraint "TEST_PK" primary key ("ID")
CREATE sequence "TEST_SEQ"
CREATE trigger "BI_TEST"
before insert on "TEST"
for each row
begin
if :NEW."ID" is null then
select "TEST_SEQ".nextval into :NEW."ID" from dual;
end if;
end;
So now what I do is put each of these into a List of Strings and execute 1 by one like this:
List<String> commands = new ArrayList<String>(4);
commands.add("Create table ...");
commands.add("Create sequence ...");
commands.add("Create trigger...");
st = con.createStatement();
for (String command : commands) {
st.execute(command);
etc...
But I get an error with the trigger statement. "Error with Oracle command: ORA-00942: table or view does not exist"
It seems to me that Oracle has not yet seen the new table at this point. or maybe my user can create tables but not triggers? If that's the case why did it work in the express application itself?
TIA

If it was a rights problem, you'd get a different ORA error stating that, it won't silently fail.
Lets not assume it is anything difficult, perhaps there is simply a typo in a name somewhere?

Sequencing and Trigger on Oracle 9i lite database

We created a schema (TESTSCHEMA) on Oracle 8.1.7 Enterprise edition and have a created a trigger which will use the sequence object to generate primary key for the table (TEST_TABLE)
Sequence creation:
CREATE SEQUENCE TESTSCHEMA.TEST_TABLE_SEQUENCE START WITH 6000 INCREMENT BY 1 MINVALUE 6000 MAXVALUE 6999 NOCACHE NOCYCLE NOORDER ;
Trigger creation:
CREATE OR REPLACE TRIGGER TEST_TABLE INSERT BEFORE INSERT ON TEST_TABLE FOR EACH ROW
DECLARE
pkValue NUMBER;
BEGIN
pkValue := 0;
Select TEST_TABLE_SEQUENCE.NextVal into pkValue from dual;
:NEW.TEST_KEY := pkValue;
END TEST_TABLE_INSERT;
We have created a snapshot of the schema on mobile server, synchronized the data with the client (Win32 for testing purpose).
The trigger works fine on the server, but when I run the same query on the lite database with msql it gives me an error:
[POL-3221] null key in primary index
I was wondering if Sequence generation and Triggers are supported on Oracle 9i lite database ? Or am I missing out something ??
Any information/ help is appreaciated
Thanks
Neeraj

You can't use SAVEPOINT / ROLLBACK TO SAVEPOINT statements in the database trigger:
ORA-04092: cannot SET SAVEPOINT in a trigger
ORA-04092: cannot ROLLBACK in a trigger
I am not sure what you need exactly, but you can try this:

I just copy pasted your code.
Works just fine.
I believe you issue is realed to TOAD rather than pl/sql.
Would have loved to help you but i use pl/sql developer.
However if possible send a screen shot.

Help on Sequence and Procedure

Hi all,
I have a situation like this
I have 10 different tables like a,b,c,d,e,f
But i have same columns in all tables
like
id
Created_date,
Current_user,
updated_by,
updated_date
I created a sequence and triggers on a table like below
CREATE SEQUENCE x_SEQUENCE START WITH
150001 INCREMENT BY 1 MAXVALUE 999999
CYCLE;
CREATE TRIGGER xi_trigger
BEFORE INSERT ON x_table FOR EACH ROW
BEGIN
SELECT x_SEQUENCE.NextVal,USER,SYSDATE INTO :NEW.CTUT_ID,
:NEW.CURRT_USER_ID,:NEW.CREATED_DATE FROM DUAL;
:NEW.CREATED_BY := :NEW.CTUT_ID;
END;
CREATE TRIGGER xU_trigger
BEFORE UPDATE ON x_table FOR EACH ROW
BEGIN
SELECT USER,SYSDATE INTO :NEW.CURRT_USER_ID,:NEW.UPDATED_DATE FROM DUAL;
:NEW.UPDATED_BY := :NEW.CTUT_ID;
END;
everything is working fine for one table
1) Can anybody help me how to create a procedure with Trigger code
so that i can call that procedure in all tables
like
CREATE TRIGGER xi_trigger
BEFORE INSERT ON x_table FOR EACH ROW
BEGIN
x_procedure;
end;
2) When sequence is completed i mean when it reach max value how to display message
Thanks for your help

Here's one way of doing it:
CREATE PROCEDURE audit_action
( pn_id OUT NUMBER
    , pv_by OUT VARCHAR2
    , pd_on OUT DATE )
IS
   ln_seq NUMBER;
   ld_on DATE;
   lv_by VARCHAR2(30);
   x_seq exception;
   pragma exception_init(x_seq, -8004);
BEGIN
   SELECT my_seq.NEXTVAL, USER, SYSDATE
   INTO   ln_seq, lv_by, ld_on
   FROM   dual;
   pn_id := ln_seq;
   pv_by := lv_by;
   pd_on := ld_on;
EXCEPTION
   WHEN x_seq
   THEN
      RAISE_APPLICATION_ERROR(-8004, 'MY_SEQ has run out of numbers!');
END audit_action;
/and here's how you call it:
CREATE TRIGGER xi_trigger
BEFORE INSERT ON x_table FOR EACH ROW
BEGIN
    audit_action (:NEW.ctut_id, :NEW.currt_user, :NEW.created_date);
END xi_trigger; Warning: I have not run this code (can't be bothered with the set-up) but it is logically correct, so it should work with (at worst) minor syntactical tweaking.
Cheers, APC
P.S. CURRENT_USER is a misleading column name, it ought to be called CREATED_BY.
P.P.S. It is very bad practice to have sequences run out at all. Unless you have a very good reason I strongly urge you not to set MAXVALUE when you create your sequences.

Sequence and Integrity

as developer which is newly use oracle.. I have confusion
It is sequence.
in contrast with MySQL or SQL Server, db system I had work in, oracle didn't have auto increment column instead oracle has sequence
I think sequence and id column have link, but I get confused cause there no link between both
someone could insert id without sequence
after that I search this forum and found out
remedy of this is trigger. place trigger for insert operation
What is the best pratice for sequence? particulary when I create table
thanks & regards

Hi Hemanth,
One Question on the below descriptive
A Sequence can be shared across multiple sessions and sessions do not have to "wait" on each other to increment sequence values.
A Trigger is one way to implement a Sequence to set a Column Value.
{code}
Looking into the above statements and usage, we might get Gap Sequence (no exactly gap but a failing issue with primary key if we handle sequence with triggers) - When handling with multiple Sessions with triggers.
Let me know your inputs on that.

Want to record my voice in GB and trigger it through my keyboard?

want to record my voice in GB and trigger it through my keyboard and record it in my song as midi data?
anybody know if I can do this??
thanks, technoreid
imac intel Mac OS X (10.4.6)

thanks for welcoming me to the forum. this is awesome! thanks!
back in the day (1995) i used to have a program called Studiovision Pro with digidesign Session 8 and Digidesign SampleCell. and used to map my voice over the keyboard in different pitches for play back as a midi instrument in the Studiovision sequencer....
I am not looking for pitch changes this time- just trying to see if GB can at least record my voice (without pitch changing via the music keyboard) ...
just want to record my voice and trigger it several times in a song at the same pitch.
I think you answered my ?..... I think what you said will work.. sounds logical....
thanks, technoreid

Greetings, I am working in Final Cut Pro 7. In the timeline some clips show as offline. I tried going to sequence and reconnecting to media but it does not work. I can still see the video in the timeline and work with it. It just has the red box.

If the clips are not actually missing, you could try to refresh the timeline by using cmd-0 and then going to the timeline options tab. Then select name only where it says "thumbnail display". Press ok to accept the change, then repeat the process to add thumbnails back to your timeline.

What is the correct way to use Version Information from the sequence and from the deployment tool

I seem to be missing something in how the various version numbers are supposed to be used. My end goal is to log and possibly display in the UI the version of the sequence and which installer version was used to inspect a UUT. I have gotten most of the way there using:
How Can I Programmatically Query the Sequence File Version of My TestStand Sequence?
and logging this into the report with a function which contains:
Parameters.UUT.AdditionalData.SetValString("Test Version",1,RunState.SequenceFile.Data.Version),
Parameters.UUT.AdditionalData.SetFlags("",0,PropFlags_IncludeInReport)
The "Deployment Version" in the TestStand Deployment Utility auto incrementing the 3rd position of a version number while the sequence auto increment is working on the 4th.
My first question is are these 2 version numbers in anyway supposed to be related to each other? As it seems to me you would want those 2 reversed, I can make several installers based on sequence version X, making changes to what supporting files are also installed.
If they are not related as I suspect that they are not. How do I programatically grabed the installer version and also log that into the result report?
is there an option to perform a custom deployment build step to log the deployment version before it builds and then reference that log at runtime of the test?

Hi,
The sequence file version and deployment versions are not related.
You can build the installer with whatever version you want using the command line :

Hope this helps,

Project renames sequence and all clips in the sequence when a clip is added

My project is renaming my sequences and the clips in those sequences whenever I add a clip. For example, I have a sequence called "dance section 2", which contains 20 some-odd clips with various names. When I add a clip named "drop from above", the name of the sequence is changed to "drop from above", and the name of every other clip in the sequence is also changed to "drop from above" (video, audio, stills, everything). When I add a clip named "spins", all the names are changed to "spins".
The name of the sequence is changed in both the timeline and the browser, but the names of the other clips are changed only in the timeline. In the browser, they keep their old names. The exception to this is the last clip added before the name changer. For example, if I add "drop from above" to the sequence, and then add "spins", the clip named "drop from above" is renamed "spins" in the browser as well as in the timeline, but the other clips are renamed only in the timeline.
The clips in the sequence also keep their original content - so the sequence looks the same as it did before, but all the names of the clips are changed.
This is only happening in one project. All of my other projects are working fine.
I've tried restarting and deleting preferences. I've also looked at the autosave vault for the project. The backup projects saved after a certain time all behave the same way, and the projects before that time all behave normally. I can't imagine what would have caused this, though, since I've been working on this project all day and nothing's happened to my computer or hard drive or anything.
Also, there are no freeze frames at the beginnings of my sequences (I read another thread with a somewhat similar issue and getting rid of freeze frames seemed to help that person).
I'm in FCP 7.0 on a Macbook Pro.
Thanks in advance for your help!

Welcome to the discussions...
I've had this happen. My guess is that it's related to round-tripping to/from Color, but I can't be sure. IMHO, the sequence is corrupted. I just dealt with it for a while, then rebuilt it by making changes from an earlier version.
Sorry I don't have a better solution, but at least you know you're not alone.
