I want to update field data_aktualizacji when some row in the same table is updated. I created the following compound trigger.
CREATE OR REPLACE TRIGGER oferta_update_trigger
FOR UPDATE ON oferty
compound TRIGGER
id_oferty number(10);
AFTER EACH ROW IS
BEGIN
id_oferty := :new.idk;
END AFTER EACH ROW;
AFTER STATEMENT IS
BEGIN
UPDATE oferty SET data_aktualizacji = SYSDATE WHERE idk = id_oferty;
END AFTER STATEMENT;
END;
/
When I want to update some record, I get the following error.
SQL Error: ORA-00036: maximum number of recursive SQL levels (50) exceeded.
How to solve this problem? I this that some loop is created, but I don't know, how to workaround this.
Update oracle to alter the column to default to sysdate
Alter table oferty alter column data_aktualizacji set default sysdate
No need for trigger at all
As Ctznkane525 wrote, you definitively should use default-value to perform this action.
If you don't want to use default you can modify new.data_aktualizacji:
CREATE OR REPLACE TRIGGER oferty_update_aktualizacji
BEFORE INSERT OR UPDATE
ON oferty
FOR EACH ROW
DECLARE
BEGIN
:new.data_aktualizacji:= sysdate;
END;
I checked all my fields and everything is fine but i keep on getting this error
When i write this trigger on sql command it says trigger has been created but when i checked on the trigger it showed invalid
This is my trigger
create or replace trigger "Max_Crew_T1"
Before insert or update on "CREW"
for each row
declare
v_count number;
Begin
select count(*) into v_count from CREW where AirPlaneID=:NEW.AirPlaneID;
if
v_count > 5
then
Raise_Application_ERROR(-20343,'Crew number exceeded');
END IF;
END;
HERE IS THE ERROR MESSAGE;
PLS-00049: bad bind variable 'NEW.AIRPLANEID'
click on the link below for table desc
The error is because you defined the airplane id while creating the table in quotes. I.e "AirPlaneID" hence you need to do the same in the trigger.
It is not a good practice to define case-sensitive columns with quotes as it causes all these issues, its much better to define without quotes eg. create table crew (airplaneid number(6))..etc. Anyway..
Please use below:
create or replace trigger "Max_Crew_T1"
Before insert or update on "CREW"
for each row
declare
v_count number;
Begin
select count(*) into v_count from CREW where "AirPlaneID"=:NEW."AirPlaneID";
if
v_count > 5
then
Raise_Application_ERROR(-20343,'Crew number exceeded');
END IF;
END;
I am having an issue when creating the auto increment trigger in Oracle 11g. If someone can point out what I am doing wrong, I would really appreciate it. My script for the sequence is this :
CREATE SEQUENCE SPSS_QUOTE_LINE_ITEMS_SEQ start with 1
increment by 1
minvalue 1;
The script for trigger:
CREATE OR REPLACE TRIGGER SPSSQUOTELINEITEMS_ON_INSERT
BEFORE INSERT ON SPSS_QUOTE_LINE_ITEMS
FOR EACH ROW
BEGIN
SELECT SPSS_QUOTE_LINE_ITEMS_SEQ.NEXTVAL
INTO :new.line_num
FROM dual;
END;
The error I am getting:
[Code: 900, SQL State: 42000] ORA-00900: invalid SQL statement
Thanks a lot.
The correct way of doing this to modify your trigger as below:
CREATE OR REPLACE TRIGGER SPSSQUOTELINEITEMS_ON_INSERT
BEFORE INSERT ON SPSS_QUOTE_LINE_ITEMS
FOR EACH ROW
BEGIN
:new.line_num := SPSS_QUOTE_LINE_ITEMS_SEQ.NEXTVAL;
--No need to write any Select Into statement here.
END;
Or if i follow your way then it goes like
CREATE OR REPLACE TRIGGER SPSSQUOTELINEITEMS_ON_INSERT
BEFORE INSERT ON SPSS_QUOTE_LINE_ITEMS
FOR EACH ROW
declare
var number;
BEGIN
SELECT SPSS_QUOTE_LINE_ITEMS_SEQ.NEXTVAL
INTO var
FROM dual;
:new.line_num :=var;
END;
You normally use the terms in a trigger using :old to reference the old value of the column and :new to reference the new value.
I'm trying to create a trigger that will fire if the Prog_Type = 'EPISODE'. I am receiving a bad binding error - PLS - 000049. I believe there is something wrong with my DECLARE state
CREATE OR REPLACE TRIGGER Seas_Pk_Trigger
BEFORE INSERT OR UPDATE OF Seas_ID ON Season_Table
FOR EACH ROW
DECLARE
Prog_Type VARCHAR2(7);
BEGIN
IF (:OLD.Prog_Type <> 'EPISODE')
THEN SELECT Seas_ID_Seq.nextval into :new.Seas_ID from dual;
END IF;
END Seas_Pk_Trigger;
/
If you are referencing a column in your table, you do not need to declare the column Prog_Type to reference it with a :OLD or :NEW pseudo-record. If Prog_Type is in your table (which I assume it is), then just omit the declaration:
CREATE OR REPLACE TRIGGER Seas_Pk_Trigger
BEFORE INSERT OR UPDATE OF Seas_ID ON Season_Table
FOR EACH ROW
BEGIN
IF (:OLD.Prog_Type <> 'EPISODE')
THEN SELECT Seas_ID_Seq.nextval into :new.Seas_ID from dual;
END IF;
END Seas_Pk_Trigger;
/
I'm not sure how to interpret your statement that you only want this to fire when Prog_Type = 'EPISODE' as your trigger has a <> to EPISODE clause?
This trigger will pass on inserted values to a procedure which will insert those values in another table. I'm getting a mutating table error. How can i fix this?
CREATE OR REPLACE TRIGGER ADD_INVOICE
BEFORE INSERT OR UPDATE OF APP_NO,C_NO ON APPOINTMENT
FOR EACH ROW
DECLARE
BEGIN
POP_INVOICE(:NEW.APP_NO,:NEW.C_NO,:NEW.APP_DATE);
END;
/
CREATE OR REPLACE PROCEDURE POP_INVOICE(
I_APP_NO IN INVOICE.APP_NO%TYPE,
I_C_NO IN INVOICE.C_NO%TYPE,
I_INV_DATE IN INVOICE.INV_DATE%TYPE)
AS
CURSOR C_POP IS SELECT PRICE FROM TREATMENT T,APPOINTMENT A
WHERE T.TRT_NO=A.TRT_NO
AND A.APP_NO=I_APP_NO;
V_BILL INVOICE.BILL%TYPE;
BEGIN
OPEN C_POP;
FETCH C_POP INTO V_BILL;
UPDATE INVOICE
SET INV_NO=INV_IDSEQ.NEXTVAL,
APP_NO=I_APP_NO,
C_NO=I_C_NO,
BILL=V_BILL,
INV_DATE=I_INV_DATE;
END;
/
The problem is caused by referencing the table with the trigger on it within the trigger itself. Changing the procedure to accept the TRT_NO as a parameter removes the need to include APPOINTMENT in the query, and so will avoid the mutating table exception. Depending on how many records there are for each treatment, you could even incorporate the cursor into your UPDATE statement.
I think this should do it, although I haven't been able to check against a database.
CREATE OR REPLACE TRIGGER ADD_INVOICE
BEFORE INSERT OR UPDATE OF APP_NO,C_NO ON APPOINTMENT
FOR EACH ROW
DECLARE
BEGIN
POP_INVOICE(:NEW.APP_NO,:NEW.C_NO,:NEW.APP_DATE,:NEW.TRT_NO);
END;
/
The revised procedure:
CREATE OR REPLACE PROCEDURE POP_INVOICE(
I_APP_NO IN INVOICE.APP_NO%TYPE,
I_C_NO IN INVOICE.C_NO%TYPE,
I_INV_DATE IN INVOICE.INV_DATE%TYPE,
I_TRT_NO IN APPOINTMENT.TRT_NO%TYPE
)
AS
CURSOR C_POP IS SELECT PRICE
FROM TREATMENT T
WHERE T.TRT_NO = I_TRT_NO;
V_BILL INVOICE.BILL%TYPE;
BEGIN
OPEN C_POP;
FETCH C_POP INTO V_BILL;
CLOSE C_POP;
INSERT INVOICE
(inv_no, app_no, c_no, bill, inv_date)
VALUES
(INV_IDSEQ.NEXTVAL, I_APP_NO, I_C_NO, V_BILL, I_INV_DATE);
END;
