I know it is very common issue and have read multiple resources on the same but could not fix it.
I'm using Query Window within Visual Studio
Trigger:
TRIGGER "CERTCATID_TRIG"
BEFORE
INSERT
ON "CertCategoryValues"
FOR EACH ROW
BEGIN -- executable part starts here
SELECT SEQ_CERTCAT.NEXTVAL
INTO :new.id
FROM dual;
END;
Table
CertCategoryValues table with id column but still getting same error.
ERROR .CERTCATID_TRIG' is invalid and failed re-validation
Answer by #GriffeyDog in comments Hope this helps someone
"If you use lowercase for Oracle objects, you'll have to surround object names with quotes (") and match the case exactly to get it to work."
It worked.
TRIGGER "CERTCATID_TRIG"
BEFORE
INSERT
ON "CertCategoryValues"
FOR EACH ROW
BEGIN -- executable part starts here
SELECT SEQ_CERTCAT.NEXTVAL
INTO :new."id"
FROM dual;
END;

So, I'm trying to use JDBC to access my Oracle DB, and I found out that, for the functions in JDBC to return results correctly, I need to make an iterator for my tables. So, after searching around and figuring out what that means, I came up with the following code snippet to get that done:
--create a sequence for use in the trigger
CREATE SEQUENCE accounts_seq;
--make the trigger on insert or update
CREATE OR REPLACE TRIGGER account_pk_trig
BEFORE INSERT OR UPDATE ON accounts
FOR EACH ROW
BEGIN
IF inserting THEN
SELECT : accounts_seq.NEXTVAL INTO : NEW.accountnumber FROM dual;
ELSE IF updating THEN
SELECT : OLD.accountnumber INTO : NEW.accountnumber FROM dual;
END IF;
END IF;
END;

And, not only is Oracle SQL Developer putting the dreaded red underline of doom in the space after the semicolon put after end, but also on the forward slash to end the code block. As far as I've seen, this appears to be correct to the Oracle SQL examples of trigger definitions that I've seen... and I'm not sure if this is due to the Oracle SQL Developer not recognizing NEXTVAL as a keyword... because it isn't highlighted like the others are.
After some fiddling around, I realized that the "ELSE IF" opened a new IF statement that I didn't close. But, still getting Bad Bind variable error.
For those of you who would want to make sure that the "accountnumber" field exists in the table "accounts", here's my definition for the "accounts" table.
CREATE TABLE accounts (
accountnumber NUMBER NOT NULL,
routingnumber NUMBER NOT NULL,
acctype VARCHAR2(20),
balance NUMBER (*,2),
ownerid NUMBER,
CONSTRAINT accountnumber_pk PRIMARY KEY (accountnumber)
);
You have two major errors in your PL/SQL code:
First the select : is wrong. You can't just throw in a colon like that. The NEW and OLD records do need a colon, but without a space. :new, not : new.
To store the result of a query in a variable you need:
select accounts_seq.NEXTVAL
INTO :NEW.accountnumber
FROM dual;
But you don't need a SELECT for that, you can use a simple variable assignment:
:NEW.accountnumber := accounts_seq.NEXTVAL;
You also have two END IFs although you only have a single IF
And as documented in the manual it needs to be ELSIF, not ELSE IF
Putting all that together, your trigger should be:
CREATE OR REPLACE TRIGGER account_pk_trig
BEFORE INSERT OR UPDATE ON accounts
FOR EACH ROW
BEGIN
IF inserting THEN
:NEW.accountnumber := accounts_seq.NEXTVAL;
ELSIF updating THEN
:NEW.accountnumber := :OLD.accountnumber;
END IF;
END;
/
As the trigger is declared as BEFORE INSERT OR UPDATE the ELSIF is actually useless, because it can only be insert or updating nothing else. So instead of ELSIF updating THEN you could simply write ELSE
Am trying to write a trigger which has to restrict for zero salary before insertion.
I have written but its not working. I am getting an error as trigger is invalid and failed re validation.
Code:
create or replace trigger emp_sal
before insert or update on employee
referencing new as new old as old
for each row
begin
if :new.salary<=0 then
raise_application_error (-20999,’salary is zero’);
end if;
end;
/
Please let me know where the problem is. Thank you
Your code is okay. The only problem I can imagine is that you were using the wrong character for the single quotes in ’salary is zero’.
Run show errors right after you created the trigger (assuming you're uning sqlplus)
But I agree with zerkms. This is a case for a check constraint.
I'm having the following problem with an old database. We migrated from sql to oracle recently and I'm having trouble with an insert statement where the column name is "default". Any ideas (I'm not allowed to change the column name, that would be by far the best solution!)?
It looks somehow like this, only with a billion more columns and it's inside a large if-when-else construction for validating issues, so I can't drop the execute immediate.
EXECUTE IMMEDIATE 'INSERT INTO trytable (ID, "DEFAULT") VALUES (''monkey1'', 0)'
I don't think the problem comes from your column name, as shown in this working example:
SQL> CREATE TABLE trytable (ID VARCHAR2(10), "DEFAULT" NUMBER);
Table created
SQL> BEGIN
2 EXECUTE IMMEDIATE
3 'INSERT INTO trytable (ID, "DEFAULT") VALUES (''monkey1'', 0)';
4 END;
5 /
PL/SQL procedure successfully completed
Technically, you can have a table column name named DEFAULT, even if it's generally a bad idea that will lead to confusion. You will only be able to interact with it through the double-quote " syntax because DEFAULT is a reserved word.
If you specify double quotes around identifiers, Oracle will treat them as case-sensitive, so you have to make sure that they match the table specs.
In your case, it would help to have the specific error message.
The below will executes if your column name is "DEFAULT":
BEGIN
EXECUTE IMMEDIATE 'INSERT INTO TRYTABLE(ID, "DEFAULT")VALUES(''monkey1'',0)';
END;
"DEFAULT" and "default" makes difference.
I am new to the sql. I want to create a trigger for copying values between tables.
basically, the task I want to finish is forwarding students' message table values to specific staff_maibox
here is the code.
drop trigger forward_msg_to_staff;
create or replace trigger forward_msg_to_staff
update on message
for each row
declare
message_id VARCHAR2(10);
client_id NUMBER(10);
staff_id NUMBER(5);
message_date DATE;
message_title VARCHAR2(20);
staff_mailbox VARCHAR2(255);
begin
insert into staff_mailbox(message_id, client_id, staff_id, message_date, message_title, staff_mailbox)
values(:new.message_id, :new.client_id, :new.staff_id, :sysdate, :new.message_title, :old.staff_mailbox)
end;
/
is this code correct?
Please advise. thanks in advance.
You're getting an error because you're missing either the BEFORE or AFTER keyword from the CREATE TRIGGER statement.
These are required as indicated in the documentation:
Additionally:
There's no need to declare all the variables, you're not using them
:sysdate is incorrect, you're not binding it. You can just use sysdate instead as you would in standard SQL or PL/SQL.
You're missing a semi-colon after the VALUES clause of the INSERT statement.
Putting this together your trigger may look like this
create or replace trigger forward_msg_to_staff
after update on message
for each row
begin
insert into staff_mailbox( message_id, client_id, staff_id, message_date
, message_title, staff_mailbox )
values ( :new.message_id, :new.client_id, :new.staff_id, sysdate
, :new.message_title, :old.staff_mailbox );
end forward_msg_to_staff;
/
Note that I've used the trigger name in the END as well. This is for convenience only, it makes it obvious where the trigger ends...
If you want to see what errors your're getting when you're creating a trigger use show errors as a_horse_with_no_name suggests. This shows any compilation errors, which is invaluable for tracking them down.
I am writing the below queries in oracle:
DBMS_OUTPUT.....'Ashish'
Select col1 into val1 from tab_1
DBMS_OUTPUT.....'Ubale'
when I run this procedure I get the output as "Ashish" only why?
also what will be the value of v_val1 variable
Note: the table does not contain any records
Since the table is empty, the "select into" statement will raise the NO_DATA_FOUND exception. That's why you don't get the second message. val1 will have the same value as before the select - i.e. null if you didn't previously assign a value.
The fact that you don't know you got the NO_DATA_FOUND exception suggests that you have made one of the biggest errors PL/SQL developers ever make:
EXCEPTION
-- Never do this in real code!!!
WHEN OTHERS THEN NULL;
END;
Did you get error? If the table doesn't have rows in it. You might get no_data_found exception.
By the way, where is your entire code?
