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));
Table created.
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.

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:

Use of sequence in trigger

I need to ensure that a unique key value is stored in a column. Values must be persistent across DB restores. A Sequence is fine to initially populate the column, but I must also ensure a key is applied to records inserted later (by third-party code unaware of the key column).
If I try to plant a trigger to set the column value to sequence.nextval, compilation error occurs: "PLS-00357: ... Sequence reference ... not allowed in this context."
Are special tactics needed to allow use of sequences in triggers? Can you suggest another approach to enforce key maintenance?

Log in as scott/tiger and do the following:
CREATE SEQUENCE deptno
START WITH 50
INCREMENT BY 10;
CREATE OR REPLACE FUNCTION next_dept
RETURN NUMBER AS
v_new_dept dept.deptno%TYPE;
BEGIN
SELECT deptno.NEXTVAL
INTO v_new_dept
FROM DUAL;
RETURN v_new_dept;
END;
CREATE OR REPLACE TRIGGER new_dept
BEFORE INSERT ON dept
FOR EACH ROW
BEGIN
:NEW.deptno := next_dept();
-- this will fail when next_dept
-- returns 100 because deptno is
-- only 2 digits.
END;
INSERT INTO dept
-- you must provide a dummy deptno
-- to satisfy the PK constraint
VALUES(0, 'SURFING', 'MAUI');

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 that's the case why did it work in the express application itself?No, DDL commands cause an explicit commit. As soon as you invoke them, the change is permanent. 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?

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.

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

Problem using a sequence in a trigger

I am creating a table, sequence and trigger as below. When I insert into the table I get the error message
'ORA-04098: trigger 'SIMS2.BEF_INS_MATERIAL_COST' is invalid and failed re-validation'
I am using TOAD rather than SQL Plus to do all this. Any idea what is causing the problem?
create table material_costs
material_id NUMBER(8) not null,
material_desc VARCHAR2(50),
material_rate NUMBER(8,2)
tablespace sims2data;
create index material_costs_1
ON material_costs (material_id)
tablespace sims2index;
create sequence material_costs_seq
increment by 1
start with 1
nomaxvalue
nocycle
noorder
cache 100;
create or replace trigger bef_ins_material_cost
before insert
on material_costs
for each row
begin
if inserting then
select material_costs_seq.nextval into new.material_id
from dual;
end if;
end;

Some older versions of Oracle do not allow the direct assignment of a sequence to the column, so you could try
CREATE OR REPLACE TRIGGER bef_ins_material_cost
BEFORE INSERT ON material_costs
FOR EACH ROW
DECLARE
l_seqval NUMBER;
BEGIN
   SELECT material_costs_seq.nextval INTO l_seqval
   FROM dual;
   :NEW.material_id := l_seqval;
END; The TOAD editor does not require the :new syntax because new.material_id is, at least potentially, a valid construct, and can only be resolved at compile time by Oracle. Oracle will certainly complain about new.material_id not being declared.

How to create an INSERT trigger which creates a "sequence number"

Imagine a table T_Q with columns C_1, C_2, C_3 and UN_123.
C_1, C_2 and C_3 are all numeric and given by the user.
UN_123 has to be a calculated sequence number starting by 1 and incremented by 1 for each combination of C_1, C_2 and C_3, i.e., the sequence number depends on the key values C_1, C_2 and C_3.
Could anybody provide a code sample on how to create a BEFORE INSERT trigger , which calculates the value of the column UN_123 based on the values of C_1, C_2 and C_3 ??
Premise: Rather than using any sequence, the trigger code should only be based on the table T_Q

The sequence and trigger compiled without problem. I just can't seem to insert that value into the query. Any help would be appreciated.

you are defeating the purpose of trigger which is before insert so just rewrite the query and remove the column for which value will be inserted using the created sequence and your code will work.

Sequence inside a Trigger ??

Is it possible to use a sequence inside trigger's definition ?
I don't understand why when i give a static value to my RowId in a trigger's definition it works, but when get a value from a sequence, the trigger become invalid.

Trigger/Sequence not in ddl preview when comparing models

Hi,
I've a problem with incremental DDL generation and trigger/sequence (auto-increment).
First case :
I've created a table and generated it in my Oracle database.
Then, I've defined on my primary key column the "Auto-increment" and "Identity column" to Yes (and of course sequence and trigger names filled).
If I generate DDL (File/Export or Generate DDL button), no problem. The DDL script contains the sequence and trigger defined in auto-increment properties.
But if I compare my model and the database (Import data dictionnary, swap target...), the sequence and the trigger are not in the DDL preview.
Second case :
If I create a new table in my relational model, with filled auto-increment properties, and then I compare model and db, the new table is created, with associated sequence and trigger. This is completely normal.
Last case :
A trigger manually defined in physical model is not in DDL preview if the table already exists in database. If the table doesn't already exist in db, all statements (table, sequence, trigger) are generated.
my conclusion : auto-increment properties are not taken into account in the incremental DDL generation if the table already exists.
Can you confirm this ?
thanks
regards
Fabrice
(Data modeler 3.1.4)

Hi Fabrice,
A trigger manually defined in physical model is not in DDL preview if the table already exists in database.Yes. This is true.
my conclusion : auto-increment properties are not taken into account in the incremental DDL generation if the table already exists.The actual situation is that auto-increment properties are not taken into account in the incremental DDL generation if the column already exists.
