I have created a trigger for after insert which updates a table when there is a row inserted in that table. The update is on a column which stores the application description along with the sequence number. Now my requirement is that sequence number should be unique only with in an application but not with in the table.Say the row entry can be as follows:
App_Desc Request_ID ----------------------- DEV 100 1 DEV 101 2 STG 100 3 STG 101 4
Here Request_ID is unique But the sequqnce thats created for DEV (100,101) should take an entry of 102 for the next entry for DEV and same applies for STG. So I have to use the same sequqnce for all the application.
The below trigger is running fine without any error ,but i wasn't able to perform the exact logic by the below trigger.IF, inserting multiple row then the SIVNUM field gets the same sequence number for each row , without incrementing the value for the next row.
Only the sequence value increases on the next set of row ow's inserted
Example (inserting 2 rows ) based on the below trigger:
i would like to create a sequence inside a dml trigger. Is it possible? I created a trigger and it is compiled sucessfully.
create or replace trigger tri_update_test after delete on test declare pragma autonomous_transaction;
[code]...
trigger created sucessfully.And i try to delete data from the test
delete from test where id=5;
Output:
ERROR at line 1: ORA-01031: insufficient privileges ORA-06512: at "SCOTT.TRI_UPDATE_TEST", line 4 ORA-04088: error during execution of trigger 'SCOTT.TRI_UPDATE_TEST'
CREATE OR REPLACE TRIGGER audit_emp AFTER INSERT OR UPDATE OR DELETE ON Employee FOR EACH ROW declare my emp_audit%ROWTYPE; begin if inserting then my.action := 'I'; [code].......
It works alright but i need to enter a sequenced value to a column audit_id which is a column in the emp_audit table when a change takes place, but when i define the variable it gives be an error as bad bind variable so where can i define this column in this trigger so get a sequenced value every time i d or u occurs .

I am switching database from access to oracle 11g. I have create all the required tables, but I am stuck at one point. The previous person who created access database had auto increment with SG0101, SG0102,........ In oracle I know we can auto increment primary keys but only with the numbers not with characters.
So I have customerid which is a primary key and it automatically increments the number, but I have one more column with memberid where I am inserting all the ids that start with SG0101 bla bla.....
I already have 800 member ID's that start with SG, but that value doesnt automatically increment because I dont have any sequence or trigger to do that.
So how do I create a sequence and trigger that will automatically start value with SG and keeps auto incrementing?
I am using Oracle 10G version. I need a code base for new Sequence Trigger.
Requirement : As per the request, before INSERT trigger will generate the sequence ID from AA001 to AA999 value. But once the sequence is reached to AA999, the next sequence value will be generated normal (start from AB001 etc..).
i have an understanding about Integrity constraint checking and the trigger execution sequence, which i decsribe below.
Integrity constraint are restiction on DML operation performed by the user. When a user deletes or updates or inserts a rows in a table then oracle performs certain checking to see that the data which is effecting the row abide certain rules. There are certain per-defined set or rules that can be applied on a table such as PRIMARY KEY, FORIEGN KEY, UNIQUE, CHECK, NOT NULL etc, user-defined rules can be applied on tables by using Triggers.
In both the cases the Integrity Constraint Checking is deferred until the complete execution of the statement. All rows are inserted first, then all rows are checked for constraint violations.
So when i see the trigger execution model the following steps are performed by oracle, Oracle uses the following execution model to maintain the proper firing sequence of multiple triggers and constraint checking..This is what the Oracle Documentation Library says [extract from Oracle Database Concepts 10g Release 1 (10.1)].
1. Run all BEFORE statement triggers that apply to the statement.
2. Loop for each row affected by the SQL statement. a.Run all BEFORE row triggers that apply to the statement. b.Lock and change row, and perform integrity constraint checking. (The lock is not released until the transaction is committed.) c.Run all AFTER row triggers that apply to the statement.
4.Run all AFTER statement triggers that apply to the statement.
As for step 3 here the checking of the constraints for the statement is performed which where defered till the complete execution of the statement, then what is done in step 2b? what constraints are checked there?
is it possible to change the forms trigger sequence.
for example, i am writing 'when_validate_item' in item level,block level,form level.First item level will fires and then block level and at last form level. But i want to fire the trigger first at form level then block level and at last item level.
For some reason Oracle Sequence is skipping the first value. Here is an example of script.
drop sequence tseq; drop table xyz; create table xyz (sno integer); create sequence tseq start with 1; insert into xyz values (tseq.nextval); select * from xyz;
Now the runtime of the script in SQL Developer:
drop sequence tseq succeeded. drop table xyz succeeded. create table succeeded. create sequence succeeded. 1 rows inserted SNO ---------------------- 2
Why is it skipping the starting value 1. Is there something new in 11g that is causing it to skip the first value. I have many scripts and they all are having errors due to this issue.
I have round about 100 sequences in a schema. How can i identify that which sequences are not used for a long time. Or How can i identify the last date when that sequence is used.
In our production, we have two nodes in the cluster. We use the sequence for one of the main table for primary key. Our application is expecting sequence number increments along with created date time stamp. Right now sequences are cached for each node and it creates problem for the application. We would not like to use NOCACHE option because it causes performance issue.
This is the current scenario -
Transaction #1 on Node 1 - Seq ID 1 - Time Stamp 12:01 Transaction #2 on Node 2 - Seq ID 51 - Time Stamp 12:02 Transaction #3 on Node 1 - Seq ID 2 - Time Stamp 12:03
When I try to query based on the time stamp, primary should also go up. To be very clear on what I would like to have, please consider the following example.Without using NOCACHE option, I need to have the data in the following order.
Transaction #1 on Node 1 - Seq ID 1 - Time Stamp 12:01 Transaction #2 on Node 2 - Seq ID 2 - Time Stamp 12:02 Transaction #3 on Node 1 - Seq ID 3 - Time Stamp 12:03
In other words, sequence number should always increment along with the time.
I have Created sequence in oracle 10G and its working fine. its showing THE NUMBER IS 2
SQL> DECLARE NUM NUMBER; 2 BEGIN 3 select SERIAL_NO.NEXTVAL into num from dual; 4 DBMS_OUTPUT.PUT_LINE('THE NUMBER IS ' ||NUM); 5 END; 6 / THE NUMBER IS 2
PL/SQL procedure successfully completed.When i execute this code in oracle 11G then it does not show output.
SQL> DECLARE NUM NUMBER; 2 BEGIN 3 NUM :=SERIAL_NO.NEXTVAL; 4 DBMS_OUTPUT.PUT_LINE('THE NUMBER IS ' ||NUM); 5 END; 6 /
PL/SQL procedure successfully completed. SQL> Why this is not showing output as THE NUMBER IS .
I created a Table with a single column varchar2.. in which I wanted to insert value like 'BBBBAB1'... till 'BBBBAB100'
Created a sequence starting with 1...
and inserted single row, and multiple rows using loop also; by using below code -
insert into Trans SELECT CONCAT('BBBBAB', Trans1.NEXTVAL) from dual;
but whenever I see the values they are not as required ... 'BBBBAB1' but one character 'B' is missing, and the values populating are 'BBBAB1'.. 'BBBAB100'
I have a table called "Subjects" which lists subjects to match with notations in another table I have created a simple sequence (CREATE sequence subjectid) to created the subject id for the table. But I notice that if there is a skip in the date, the sequence increments automatically when I am not even using it. It even appears to be incrementing even when I am not doing any database activity.
This is not an issue of data integrity, because the values in the subject_id column do not need to be sequential, they just need to be unique. But it really has me curious. I created another table called "keep_track" to keep track of what is happening:
Can we use the sequence.nextval,sequence.currval inside case block.
CREATE TABLE EQUALITY_TEST(NUM1 NUMBER, NUM2 NUMBER, SEQ NUMBER); INSERT INTO EQUALITY_TEST VALUES ( 2 ,0 , NULL); INSERT INTO EQUALITY_TEST VALUES ( 2 ,2 , NULL); INSERT INTO EQUALITY_TEST VALUES ( 2 ,2 , NULL); INSERT INTO EQUALITY_TEST VALUES ( 12 ,2 , NULL); INSERT INTO EQUALITY_TEST VALUES ( 12 ,12 , NULL); INSERT INTO EQUALITY_TEST VALUES ( 12 ,12 , NULL); CREATE SEQUENCE SEQ_TEMP START WITH 100 INCREMENT BY 1;
Now i need to update SEQ column with SEQ_TEMP sequence. When NUM1,NUM2 values are unequal sequence should be incremented otherwise need to use the same sequence number(CURRVAL)
I have tried like this
UPDATE EQUALITY_TEST SET SEQ= CASE WHEN NUM1=NUM2 THEN SEQ_TEMP.NEXTVAL ELSE SEQ_TEMP.CURRVAL END ; SELECT * FROM EQUALITY_TEST;
I'm having some difficulty getting a simple SQL statement to work. It uses bind variables, but has a problem when I introduce a sequence:
INSERT INTO AE_MASTER.STAGE_USAGE (STAGE_USAGE_ID, ANIMAL_USAGE_ID_FK) VALUES (AE_MASTER.AE_GENERIC_SEQ.NEXTVAL, :dummy)
==> ORA-00942: table or view does not exist
But if I remove the sequence, it works:
INSERT INTO AE_MASTER.STAGE_USAGE (STAGE_USAGE_ID, ANIMAL_USAGE_ID_FK) VALUES (1, :dummy)
==> Success
So you might think there is a problem with the sequence, but if I use a name that doesn't exist, it tells me so:
INSERT INTO AE_MASTER.STAGE_USAGE (STAGE_USAGE_ID, ANIMAL_USAGE_ID_FK) VALUES (xxxAE_MASTER.AE_GENERIC_SEQ.NEXTVAL, :dummy)
==> ORA-02289: sequence does not exist
So I'm a bit stumped as to why it's not working! Is it not possible to use sequences with bind variables?
In the past I have gotten around this by using a SELECT statement to get the sequence number then following it with the INSERT statement, but this time I'd really like to get it all done in the same statement if possible.
I have a following select statement where I am not generating a sequence in any of these WHERE clause, GROUP BY or ORDER BY clause, DISTINCT clause, along with a UNION or INTERSECT or MINUS or sub-query.
I have query like this
"SELECT AER_ID_TEMP.AER_ID, AER_ID_TEMP.D__PRNO, AER_ID_TEMP.D__PCNT, CAST((select char_value from aris_param_data where param_id = 101)||seq_record_id.nextval AS INT) as RECORD_ID FROM AER_ID_TEMP"
but still encountering a error "ORA-02287 sequence number not allowed"
