SQL & PL/SQL :: Create Trigger Not Working For Auto-increment
Jun 16, 2010
Step1
CREATE TABLE test
(id NUMBER PRIMARY KEY,
name VARCHAR2(30));
Step2
CREATE SEQUENCE test_sequence
START WITH 1
INCREMENT BY 1;
Method1 Follow Step1 and Step2 and create a Trigger as below :
CREATE OR REPLACE TRIGGER test_trigger
BEFORE INSERT
ON test
REFERENCING NEW AS NEW
FOR EACH ROW
BEGIN
SELECT test_sequence.nextval INTO :NEW.ID FROM dual;
END;
/
Method 2 Follow Step1 and Step2 and directly have an insert statement as below:
INSERT INTO test (id, name) VALUES (test_sequence.nextval , 'Jon343');
Method 1, the Trigger is not getting created, however by following Method 2, I am able to generate auto-increment number.
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'm trying to create a sequence for a primary key to simply auto-increment by the default of 1. I have a sql script written to generate mt tables, and I'm not sure how to modify the script to include the sequence. I also just want the sequence for a specific column, ie, PK, not the PK in all tables.
Here's a snippet from my script:
create table image ( image_id int NOT NULL, source_id int NOT NULL, CONSTRAINT image_id_pk PRIMARY KEY (image_id), CONSTRAINT fk_source_id FOREIGN KEY (source_id) REFERENCES source(source_id) );
Would I add the create sequence statement right after the create table, and if so, how do I apply the sequence to only 1 table and a single column?
I have a table abc with name and phone_number columns in it,and this table contains 100 records. Now I want to add a column say ID as primary key for this and it should be auto incremented and should have primary key for the first 100 records as well.
I have already done auto increment by making sequence and trigger. but now the problem is when i am trying to retrieve data from that table it returns all data perfectly but the primary key that is my auto increment value shows blank.I am facing this problem with join query, there 4 table left joined in my query. But when I remove join from my query then it shows that value.
But i need that value in my join query.So, what is the problem and what can I do?And other thing is when I apply this query in Oracle SQL Developer, it works perfect.
My Query: return $this->db->query("select * from TBL_EMPLOYEE_BASIC left join TBL_EMPLOYEE_DETAILS on TBL_EMPLOYEE_BASIC.EMPL_ID = TBL_EMPLOYEE_DETAILS.EMPL_ID left join TBL_EMPLOYEE_EDUCATION on TBL_EMPLOYEE_BASIC.EMPL_ID = TBL_EMPLOYEE_EDUCATION.EMPL_ID left join TBL_EMPLOYEE_EXPERIENCE on TBL_EMPLOYEE_BASIC.EMPL_ID = TBL_EMPLOYEE_EXPERIENCE.EMPL_ID where
I have three tables. One for projects, one for volunteers, and a bridge entity for the many to many relationship between the Project and Volunteer.
In Project table, I have a field called, Volunteers_currently_signed_up, which means the number of volunteers currently signed up to participate in a project.
When I add an entry to my bridge entity which is composed of Volunteer_ID and Project_ID, I want the Volunteers_currently_signed_up to increment by 1, where the Project_ID in the bridge entity corresponds to that in Project.
I have very very little PL/SQL, and this is my amateur attempt so far:
CREATE OR REPLACE trigger "BI_Volunteers_currently_signed_up" BEFORE INSERT OR UPDATE ON Volunteers_in_project for each row WHERE Volunteers_in_project.Project_ID=Project.Project_ID; begin Project.Volunteers_currently_signed_up += 1; end; /
I am trying to create a table that will increment my ID by one using the following commands:
/*Creates the log needed to increment ID*/ create sequence seq_log; CREATE TABLE MESSAGE_LOG_TABLE ( IDNUMBER(10)NOT NULLPRIMARY KEY,
[code]...
When I run the above my create sequence completes successfully but I get a ORA-00955: name is already used by an existing object error message on the create table. I have dropped all tables and sequences before running my command but I still get the same error message.
After it bombs out it appears that SQL+ want's more information for it begins to give me line numbers as if it is looking for a ";" to end the above command. I have to exit SQL+ and log back in to continue working.
I have 2 tables where the data is related.table ot_pack_list,ot_delv .ot_pack_list contains details of items information that are packed to be delivered sometimes what happens user may remove some items from this, and the summary column of dl_wt and dl_qty in ot_delv must get automatically changed whenever there is addition in ot_pack.
I have a trigger to automate grants to a Role whenever a table is created in my schema.I have dba rights.
CREATE OR REPLACE PROCEDURE deepa.myddl (p_ddl IN VARCHAR2) IS BEGIN EXECUTE IMMEDIATE p_ddl;
[Code].....
This works perfectly when i create a table as deepa user. But say when another User creates a table in my schema
like create table deepa.test1 ( a number) This trigger is not fired. Whenever a table is created by me or by any other user in my Schema, i need the trigger to be fired.
CODEcreate or replace trigger admin after insert on admin for each row declare bang varchar2(250):='ADMIN';
[code]...
i will try with select :new.i.column_name from dual, but not run (because i can't determination exactly column name thus i must use column_name variable)
I have created a materialized view in schema SchemaBB of Server B with a trigger
CREATE MATERIALIZED VIEW WORKAREA.TABLA_TEST70 BUILD IMMEDIATE REFRESH FAST ON DEMAND WITH PRIMARY KEY AS SELECT TEST_PK, TEST_TEXTO [code].........
All schemas have the appropriate grants.
When inserting in TABLA_TEST (SchemaAA) and refreshing MView TABLA_TEST70 things go nicely.
But, when updating a record in the original TABLA_TEST and refreshing the MView the results in TABLA_TEST in SchemaBA are as if I have deleted the record (FECHA_DELETE is set to SYSDATE).
I am trying to write a trigger on a new table. (dest_test) This is the first trigger that I have ever attempted (fairly new DBA) and I am having some trouble with the trigger body.It is a before insert trigger that will need to select from another table (dest) for a particular value being inserted (destination).
create table dest_test ( destination varchar2(4) not null, db_name varchar2(10) not null )
desc dest
[code]...
I am getting the exact opposite results than I want, though. If the value appears in dest, it is inserting into dest_test... NOT whatI want it to do!If the value doesn't appear in dest, it is throwing ora-6512 and ora-4088 errors. Is there a way to suppress these errors, or to graceful exit from the block so that the trigger completes without throwing these errors?
how to create the trigger that count the last 7 day about from sale table if the last 7 day amount is greater then 10000 then update the commission 2% other wise do nothing
I cant create a trigger for the following problem "write a trigger to change the "hiredate"(in emp tale) in the default format even if the user enters it in some other format, say year/mon/date..."
How do I create a trigger for the age. I want an alert to appear when the date of birth field is less than the age of 17. The formula is age=sysdate-dateofbirth
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:

I'm trying to create a trigger and procedure to go along with my DDL. Everything is created just fine, but when I try to execute an update on the table monitored by the trigger I get the following error:
update housing set group_num = 1 where room_num = 10
ERROR at line 1: ORA-00937: not a single-group group function ORA-06512: at "YANKEEFAN146.VIOLATION_CHK", line 6 ORA-04088: error during execution of trigger 'YANKEEFAN146.VIOLATION_CHK'

I'm looking to create an after logon trigger... my question is - can this trigger be created by any user (i.e. other than sys) and - if so - what's required to ensure it fires for EVERY other user that log's on to the database?
CREATE OR REPLACE TRIGGER tri1 AFTER UPDATE ON dept FOR EACH ROW declare pragma AUTONOMOUS_TRANSACTION; BEGIN execute immediate 'create table dept_dum as select * from dept'; END; /
SQL> update dept set deptno=23 where deptno=10; update dept set deptno=23 where deptno=10 * ERROR at line 1: ORA-01031: insufficient privileges ORA-06512: at "SCOTT.TRI1", line 6 ORA-04088: error during execution of trigger 'SCOTT.TRI1'
I am running this as scott user
My requirement is to
create table as select * from table_name where flag=1
This has to be done parallel for all the tables for which this flag is enabled and by that trigger delete all those rows which were backed up as table.
We have an application is must be connected to our database for specific requirements in our company but this application has a very bug thing as we must write the super DB password "Like HR password as example" clear in some files and these files must be shared so developers can use the HR password to do any action !!! I know that this application is a problem but we have to install
I can do this by creating trigger on each table will restrict DML. As example: if the operating system user is XXX, the trigger restrict the action. But not logic at all to create more than 1000 triggers on schema (This will impact badly on DB performance).
So, i need to create one trigger to fire before doing any DML on all schema tables. As example: If "MMM" the administrator operating system user trying to do insert action, he can do the action. BUT If "DEV" the developer operating system user trying to do insert action, the trigger must fire here to restrict this action.
Be noted also, i need this trigger not depend on any specific tool like Toad as any user can simply rename the exe file for toad then he can pass the trigger. At least, trigger must depend on (Operating system user & Action_type)
i want to give privilege of create trigger,procedures and functions privileges to a user "A"on the schema "B". how can i do it. i've already given select,insert,update,delete privilege to user "A"
how can user "A" create trigger(etc.) on tables of user "B".
I Created a form just for testing purpose [Which is i attached]
My Table is TEST0
Structure of table : --------------------------- NOVARCHAR2(5) NAME VARCHAR2(10) FLG VARCHAR2(1)
My Task is When i added a record, e.g if on form, i add name - AAD But its must save on TEST0 Table like this way EMPAAD...means always concate with 'EMP'||:Block.name while saving on database..
I know how to do with front end application, but i want to achieve this task by using trigger on backend databse...how to create a Trigger on backend....i try a one trigger but it give me error- Unable to insert Record...
I have make a new trigger.Create a trigger that inserting a new job_id MAX_SALARY assigned as the employee's salary more than 80 departmental charges
I have that code, is that correct?
CREATE OR REPLACE TRIGGER TR27 AFTER INSERT ON JOBS FOR EACH ROW BEGIN (SELECT MAX(SALARY) FROM EMPLOYEES WHERE DEPARMENT_ID=80); :NEW.MAX_SALARY := :OLD.MAX_SALARY; END;
3.CREATE OR REPLACE TRIGGER login_audit_prod_schemas AFTER CREATE OR ALTER OR DROP ON SCOTT.SCHEMA [code]....
But it don't fulfill my requirement. trigger is fired when scott perform any action. but my requirment is that trigger should be fired when create action is performed on scott by hr,sh or scott. i also want a single trigger which fulfill the requirement.
i have created a trigger on a table after update. i am using if condition if the condition is true i am passing a value and then inserting into audit table.
if(condtion) L_change_type='value' end if; if(condtion) L_change_type='value' end if; if(condtion) L_change_type='value' end if; if(condtion) L_change_type='value' end if;
Then i am inserting
Insert into audit_table(change_type.....) values(..L_change_type)...)
If i want to skip the insert statement for particular condition wt i have to do.
