SQL & PL/SQL :: Sequence Number In A Trigger
Oct 15, 2010
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 have the following select query that works perfectly fine. Returns 25 rows based on the descending order of the price.But, I want add one more expression to this list of columns in this query (apart from customer_id).
the expression should look like Cust-01 for the first customer from the below query all the way to Cust-25 for the last customer.But how can I can generate 01 to 25 in oracle?
select customer_id from
(select customer_id from capitalPLAN
where member_status = 'MEMBER' AND customer_id NOT in ('156','201','1385','2125','3906','165')
order by price desc
)
where rownum <= 25

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.

I have 3 tables whose structure is as follows:
1) Invoice
Invoice_no number(8),
Debtor varchar2(35),
Invoice Date Date,
Print Date Date,
Currency varchar2(3),
Total Amount Ex Number(11,2),
Total Amount Vat Number(11,2),
Total Amount Number(11,2),
Status Varchar2(15),
2) Invoice Line
Invoice_no number(8),
Invoice_Line_No number(8),
Description_1 varchar2(35),
Description_2 varchar2(35),
Line_Quantity Number(11,2),
Currency varchar2(3),
Line_Amount Number(11,2),
Vat Code number(1),
Status Varchar2(15),
3) vat code
vat code number(1),
Description varchar2(35),
Vat Percentage number(11,2)
Here invoice no and invoice line no are automatically generated fields?
How to generate invoice line no corresponding to invoice no and how to satisfy the following conditions:
1) total vat amount in invoice table should be automatically filled . total vat amount=(line_quantity* line_amount*vat percentage)/100
2) invoice cannot be printed, changed when status is 'closed'.
3) invoice lines cannot be added,changed or removed when status of invoice is closed
4) when any of invoice line no is changed,added, removed or invoice is changed the status of invoice should be changed to 'new'.
5) invoice date of a new invoice cannot be of the past

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:
item , refwo , sivnum
1234 , 55555 , 00001
6352 , 77777 , 00002
i want to achieve :
item , refwo , sivnum
1234 , 55555 , 00001
6352 , 77777 , 00001
CREATE OR REPLACE TRIGGER siv_mat_insert
BEFORE INSERT
ON MATUSETRANS
REFERENCING OLD AS old NEW AS new
for each row

trigger created sucessfully.And i try to delete data from the test
delete from test where id=5;
Output:

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 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.
3.Complete deferred integrity constraint checking.
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?

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"

Is there any way to get the last Sequence Number generated regardless the Sequence name? Something like dbinfo('sqlca.sqlerrd1') within Informix?
Imagine I have 2 sequences. Imagine that I run both several times until 20:00 hours. Imagine that at 21:00 hours I would like to know what was the last generated number created by any of the sequences. I don't wann know wich sequence generated the last NEXTVAL, I only want to know the value of the last NEXTVAL used.
Is it possible without mentionating the Sequence name?

I am facing issue with my sequence number about sequence number generated..I want it to follow the sequence all the time, i.e. it should take next incremental number to last generated seauence, but it generates random one all the time, i.e
s.nextval() = 4
s.nextval() = 5
s.nextval() = 10
s.nextval() = 543
s.nextval() = 544
My sequence defination is as below
CREATE SEQUENCE s
START WITH 1
MAXVALUE 999999999999999999999999999
MINVALUE 1

the first 2 record are same Pras CTI and Pras CTI so i want my sequence generate value once as below
1 Pras CTI
1 Pras CTI
2 Shariq Witness
3 Kate CTI
4 Shariq Assisted
2 Shariq Witness
Shariq and witness are repeating so same sequence number but Kate CTI occured once so nextval of sequence
How can i acivee it
CREATE TABLE EMP_INV
(

EMP_INV VARCHAR2(100 BYTE)
)
Insert into EMP_INV
(EMP_NAME, EMP_INV)

I have a result set with three columns as 'Product Category', 'Product' & 'QtySales' and 10 rows, sorted in the order Product Category, Product. This means, a product category will have one or more products under it.
Now i want to add a fourth column to my result set, which should display a incremental number sequence from starting from 1, 2, 3.. for each row. Also when the value of the Product Category (1st column) changes, this sequence should be restarted again from 1.
Col1 Col2 Col3 Col4
PC1 P1 10 1
PC1 P2 20 2
PC2 P3 30 1
PC2 P4 10 2
PC2 P5 15 3
PC3 P6 25 1

I have a table ABC with two columns NAME and SEQUENCE. The valid values of sequence are from 1..50. The table may not have all the Sequence number. For example following is the data in my table..
Quote:NAME SEQUENCE
------------------------
Jonh| 5
Amy| 1
Suresh| 3
I need a SQL to get the data like
Quote:NAME SEQUENCE
------------------------
Amy| 1
| 2
Suresh| 3
| 4
Jonh | 5
|6
|7
..
..
..
|50
Basically I want to have rows for the sequence numbers which are not present i my table. I thought of using the following query to generate a sequence and then join, but does not work.
select rownum from dual connect by rownum <=50
I tried something like
with temp as (select name, sequence from abc where supp_ref_order is not null order by sequence )
select rownum as num, temp.name from dual, temp connect by rownum <=50 where temp.sequence =num

insert into tb_test
(select case when idSeq is null then 1 else max(idSeq)+1 end, 3, 'Main street');

I have a table:
Name
_____
Smith Street
Smith Street
John Street
Ed Street
Ed Street
Ed Street
and need to assign sequence numbers only when the record (Name) changes, e.g. :
Name Seq
_____ ____
Smith Street 1
Smith Street 1
John Street 2
Ed Street 3
Ed Street 3
Ed Street 3
I have experimented with row_number partition but then i just get the sequence returning to 1 when the name value changes.
If I grouped the records by Name I would like to have unique, sequential numbers: 1, 2, 3 but where there is the same name I would like the sequence to stop and the number to replicate?

My problem, I have the query which works correctly. However as you can see there is always a sequence number in the end of variables and I am not sure the total number of cases, so I have to create a loop for the same query.
I am doing the same things on BREINV1 BREINV2 BREINV3 BREINV4... AND BRENUMINV1 BRENUMINV2... so the sequence should add a number in the end of variables...

I have a table called table 1 and I am trying to insert a few values in this table and i am constantly getting bogged down by a primary key error. Strange thing is this primary key called "ID" on the table is a system generated sequence value number. The error is
"ORA-00001: unique constraint (Schema1.LICN_PK) violated"
Table structure:
*****************************************
CREATE TABLE schema1.table1

LITM_ID NUMBER(12),
PROG_PROGRAM_CD VARCHAR2(2 BYTE),
SCHED_NBR VARCHAR2(3 BYTE),

[code]........
****************Insert statement*************
insert into table1
(id,
litm_id,
prog_program_cd,
sched_nbr,
schd_version_yr,
[code].......
why the error is coming up and any way to resolve it. I checked the max sequence number value and kept running it for a while and then tried to run my insert statement but no luck yet.
