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.
I have an issue with the oracle forms trigger. This is the scenario. The form is a query only form . A user can only query on this form . No update or insert is allowed.
The base table say TABLE1 consists of these fields. 1) pro id, pro item, empno , fname, lname, deptno .
The user can query on all items except the fname and lname.
The issue is few records in the TABLE1 have null values for the empno.
When the user queries on proid, pro item , empno or deptno - when the empno on TABLE1 is not NULL , the fname and lname should be fetched from a different table say TABLE2. otherwise, if the empno on TABLE1 is null , the fname and lname from the same table i.e, TABLE1 are retrieved. I have tried with the post change trigger on empno . Also tried the When validate item trigger . But it doesnt work the way it is expected to. what is the appropriate trigger that must be used.
i want to get the x-pos of item at the radio-change trigger but it return the error
declare x_pos number; lnum_x_pos number; lnum_width number; begin
if :radio_group = 'E' then lnum_x_pos := Get_item_property('Remarks',x_pos); Message('Position of x...'||lnum_x_pos); lnum_width := get_item_property('Remarks',width); Message('width of remarks field..'||lnum_width);
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.
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),
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:
CREATE SEQUENCE hyd1_seq START WITH 2100000 INCREMENT BY 1 NOCACHE NOCYCLE;
this is how i created a sequence in database 10g.
if :SHIP_MSTR.PLACE_FROM = 'hyd1' then SELECT hyd1_seq.NEXTVAL INTO :SHIP_MSTR.BILL_ID FROM dual;
this is how iam calling sequence in form.my problem is once the sequence is generated in form and even if i am not saving a form its generating next value next time.what i want to do is if i am not saving the form that sequence number should again come in bill_id.
I know how to create sequence in the database.But I want to create this sequence from the form by giving the name of the sequence from a filed in the form.
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 want to get serial numbers in oracle forms. i have one data block with 10 rows and a non database display item with corresponding length as that of the original data block .
when ever i am executing the form i want to see the serial number generated in the display item and when i inserted a new item or row it should show the corresponding rownum.
eg:
empno name serialno 5 tom 1 4 tinil 2 6 sofy 3 7 john 4 1 albert 5 2 michel 6
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; begin execute immediate 'create sequence t_unqid start with 1 increment by 1 nocache '
end ;trigger created successfully. 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'
Is there any way could alter the sequence depending on specific condition to start with 1 in the form builder?
i wanna to reset the sequence to 1 whenever the month change.is there any way?
Could i make detail block invisible and whenever button pressed i will display the block? I want to put the where clause for that block in the button and if the button did not pressed i want to display nothing in the detail block?
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?
I'm in an environment with Weblogic Oracle Forms 11G (Oracle Fusion Middleware). I can not update a form that is in use. I can not change the fmx file.
I have been asked to support an application which was developed in Forms 4.5. I have experience in Oracle database but I'm almost zero in any front end development.
As a first task I have been asked to remove a couple of field from one of the screen and then change the value of one of the field.
