SQL & PL/SQL :: Update Table In After Insert Trigger
Feb 1, 2011
I am calling an after insert Trigger on table1.
In the trigger I am calling a procedure that returns an error if there is any error returned from procedure. I have to update the table table1's column error_desc (for the same new inserted record for which the trigger was called) with the error received by OUT parameter of procedure called in trigger. I have to update the same record on whose insert this trigger was called.
I have a base table (Table A) block with multiple records displayed. I need to track audits to this underlying table in the following way:
If user updates a field in the block I want the pre-changed record's audit fields to be set and I need to create a copy of the record with the changed values. Basically any changes will result in the record being logically deleted, and a copy record created with the newly changed values.
Tried to implement in the block's pre-update trigger which will call a package to directly update Table A then Insert into Table A, then requery the block. Is there a clean and efficient way to do this?
i want to create a trigger that will update a table when there is an insert or update.i can't across this error that i don't even know what it means "table %s.%s is mutating, trigger/function may not see it".
*Cause: A trigger (or a user defined plsql function that is referenced in this statement) attempted to look at (or modify) a table that was in the middle of being modified by the statement which fired it.
*Action: Rewrite the trigger (or function) so it does not read that table.
CREATE OR REPLACE TRIGGER set_date_end BEFORE INSERT OR UPDATE OF issued ON shares_amount FOR EACH ROW DECLARE BEGIN INSERT INTO shares_amount(date_end) VALUES(SYSDATE); END set_date_end; /
We would like to create functions to insert and update our tables and would like to make it not possible to update and insert the table directly outside of the function. Is there a way to do that in the trigger?
I have to write a trigger where when the table is updated then one column named 'Status' should be updated as 'U' and if arow is inserted in the table then the column 'Status' needs to be inserted with value 'I'.
New to triggers....how to go with both insert and update conditions together.
Can we write a trigger which takes care of both insert and update. I have used Merge statement where I can write conditions based on insert/update done.
I am trying to write a trigger that will do an insert/delete/update into a audit table when a change has occurred on the primary table. The change will be recorded in the audit table by a incemental sequence number and the updated data.
there will be an extra column in the audit table
how to get a simplified version of this trigger.
the primary table will look like so Id_num varchar (20) code Integer desc varchar(20) sequence_num Integer
SQL> CREATE OR REPLACE TRIGGER TRI_COMPL_FEATURES 2 AFTER INSERT OR UPDATE ON COMPLEMENTS FOR EACH ROW 3 DECLARE 4 v_fno NUMBER; 5 v_tab VARCHAR2(30); 6 v_unique_id VARCHAR2(40); [code]....
Trigger created.When I am trying to insert into complements table it is throwing error as follows:
SQL> insert into complements values(19,NULL,'5',6,7,NULL,'W2023648',NULL,NULL); insert into complements values(19,NULL,'5',6,7,NULL,'W2023648',NULL,NULL) * ERROR at line 1: ORA-20010: ORA-04091: table TEEMNGWS.COMPLEMENTS is mutating, trigger/function may not see it ORA-06512: at "TEEMNGWS.TRI_COMPL_FEATURES", line 19 ORA-04088: error during execution of trigger 'TEEMNGWS.TRI_COMPL_FEATURES'
I can understand that I am trying to perform DML operation(i.e select) on table which trigger is fired.But how can I implement the same logic when AFTER INSERT OR UPDATE trigger is written.
I am ceating a trigger to...when I update or insert a record in table and if salary of that record is less than 1600 than it should be updated to 2000. My trigger is
CREATE or REPLACE TRIGGER myTrigger BEFORE UPDATE OR INSERT ON newemp FOR EACH ROW BEGIN
[code]...
There are no errors with trigger while compiling, but when I update or insert a record, it does not update the table. It looks like the trigger is being ignored.
writing a trigger body. My requirement is i need to insert a new record in a task table when ever a new record is inserted into employee table.Here in the trigger i need to select the name of the employee in the last inserted row in employee table and insert the name in task table.I tried to write the code as below
insert into task(name, date, type) values ((select name from employee where emp_id=(select max(emp_id) from employee), sysdate, 'document'));
When i am trying to insert record using trigger, it is taking last but one record from the employee table.
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.
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 have 2 identical tables....the trick is with regards to one column say column A,the first table TableA is constantly having data inserted and data updated, what im trying to do is create a before insert or update trigger that looks at column A and if column A=20 it changes this to 5 and inserts this into the tableB, everything else with the exception of Column A will be the same:-
this trigger i have done works but doesnt change the value of column A (INPUT_NADI) as i dont know how to do this:-
CREATE OR REPLACE TRIGGER UPDATE_TRG_NP_NE1_T0 BEFORE INSERT ON TESTNSS.NP_NE1_T1 REFERENCING NEW AS NEW OLD AS OLD FOR EACH ROW DECLARE BEGIN INSERT INTO NP_NE1_T0 VALUES [code]....
My scenario is I need to insert into History table when a record is been updated into a tabular form(insert the updated record along with the additional columns Action_by,Action_type(Like Update or delete) and Action Date Into History table i.e History table contains all the records as the main table which is been visible in tabular form along with these additional columns ...Action_by,action_type and action_date.
So now i dont want to create a befor/after update trigger on base table rather i would like to create a generic procedure which will insert the updated record into history table taking the page alias and pade ID as the parameters(GENERIC procedure is nothing but whcih applies to all the tabular forms(Tables) contained int he application ).
I have table t1 and t1 , I want a procedure that will insert all records from t1 into table t2 and after successfull insert table t1 should be truncated .
If their is any problem in insert in to table t2 , the truncate command should not work .
Truncate command should work only after successfully insert command .
I need to take a snapshot of a table before insert or update happens to that table.... in oracle 10g. I am reading the MV docs from oracle and below link..
[URL].......
how MV should be written for this and how to schedule it in dbms_jobs for auto refresh?
assuming that t1 is the table where DML operation are goin to happen so before any insert or update, snapshot has to be taken, and I am assuming that to do this it would look something like this?
create materialized view my_view refresh fast as select * from t1;
In a trigger(on update of a table t1) I am trying to write, I am doing an insert on t2 accessing ':new' values of the update on t1.
But in my Insert statement, I am having get one of the column values from another table. How can I write my insert statement in such a way as to insert values contained in ':new' pseudo columns and a select from another table. Below is my insert statement in the trigger : -------
IF (:old.GROUP_YELLOW <> :new.GROUP_YELLOW) THEN INSERT INTO TEST.W_THRESHOLD_LOG (THRESHOLD_LOG_WID, CHANGE_DATE, MEASURE_TYPE_WID, MEASURE_NAME, CUSTOMER_WID, CUSTOMER_NAME, USER_ID, CHANGED_ITEM, PREV_VALUE, NEW_VALUE) VALUES(TEST.W_THRESHOLD_LOG_SEQ.NEXTVAL, SYSDATE, :new.MEASURE_TYPE_WID, 'Rolling Stabilty' , :new.CUSTOMER_WID, 'Customer1', 'User1', 'GROUP_YELLOW', :old.GROUP_YELLOW , :new.GROUP_YELLOW); END IF; -------
In the above code if the hardcoded value 'Customer1' need to be picked from another table, i.e .
SELECT NAME FROM W_CUSTOMER_DIM WHERE CUSTOMER_WID = THRESHOLD.CUSTOMER_WID
how can I rewrite my query to the above value from the select into my insert statement..?
I've a one history table in which I'm putting approval history data.
For any transaction id you may have more than one record with approval status APPROVED,REJECTED,ERRORED,OVERLIMIT etc
Another program selects records from this table by passing transaction_id. For transaction id, it needs to check the most recent approved record exist or not ? If it's there then updating the record by adding comments to comments field of the same record and then delete all other records for the same transaction id.
If it does not exist then delete all other records and create one with approved status?
What's the simple and best approach to do this (sql or pl/sql)?
I know this is an old thread and I just started working with triggers. I want to check if the data being inserted is already in the table and if not insert it:
create or replace trigger t_triggername before insert on tbl_tablename for each row begin if(:new.user_id <> :old.user_id) then insert into tbl_tablename(user_id, location) values (:new.user_id, :new.location); end if; end;
what if I wanted to keep the user but only update location if the user is already in the table. I've tried doing it this way:
create or replace trigger t_triggername before insert on tbl_tablename for each row begin if(:new.user_id <> :old.user_id) then insert into tbl_tablename(user_id, location)
I am trying to insert rec into target table if those rec are not existing and trying to update those rec if they already exists from three source tables.I had seen in posts that merge cannot be used with cursor.

Create table rqst_list(id Number, --(PK) pkg_name varchar2(100), status varchar2(100))
When a record is inserted into this table(rqst_list), a trigger is fired which calls the package which is there in pkg_name.The function does some function.If there are no exceptions while executing the package, then SUCCESS needs to be updated in the table for the id for which the trigger got fired.I have used AFTER INSERT ROW level trigger.
But,the final UPDATE (UPDATE the rqst_list table to SUCCES/FAILURE)to the base table inside the package is not happening.

I would like to UPDATE the columns p1 and p2 of my table student (studentid:pk,name,p1,p2,...) for a given studentid.and I have a when-button-pressed trigger with this

when I run my form with a correct studentid, I got this error: FRM-40508: ORACLE error: UNABLE to INSERT record
but it is cworking correctly in sqlplus; and I have all priveligies.
